## Introduction

Episodes begin with a cold open, followed by the opening title sequence crediting the top four main actors and series creator. The show title and credits are accompanied by the Lost Girl Theme song. Over the top of the sequence and theme song is the voice-over monologue by the protagonist, Bo (Anna Silk), summarizing her story:
   Life is hard when you don't know who you are. It's harder when you don't know what you are. My love carries a death sentence. I was lost for years, searching while hiding; only to find that I belong to a world hidden from humans. I won't hide anymore. I will live the life I choose.
The Lost Girl Theme song was composed by Jody Colero, Marco DiFelice and Benjamin Pinkerton. Total episode running time is 44:00 minutes, including opening title sequence and closing credits roll. Episodes on Syfy in the United States are 90 seconds shorter to allow for more commercial advertisement time. Starting with Season 3, 30 seconds of story that would have otherwise been cut from the episodes for Syfy's advertising blocks were preserved by replacing the original opening title sequence with opening credits superimposed over the first scene of each episode.

## Plot
### Season 1 (2010)

Bo is a Succubus who grew up in an adopted human family, unaware of her non-human nature and of the Fae world she descended from. She began to feel "different" when she entered puberty and didn't know she was not normal until she accidentally killed her high school boyfriend by draining his life energy during her first sexual encounter. When she told her parents what had happened, they broke the news to Bo that she had been adopted (see "Raging Fae"). Not knowing what she was and what she had done, Bo hated herself and ran away from home, exchanging her previous life for one without family or friends, moving from place to place and assuming a false identity whenever she killed again.
In the first episode, Bo saves a young human woman, Kenzi, from a rapist who had surreptitiously drugged her with a "roofie" in her drink. The two quickly become friends and Kenzi decides they should team up to create a Fae/Human detective agency. Confronted by the Fae leaders of the local territory with a demand for her to choose a side – either "Light" or "Dark" – Bo declares herself neutral, deciding instead to side with humans after Kenzi risks her life to find out where Bo had been taken by force and what they were doing to her.
Most of the Fae considered Bo an unknown entity that should either be eliminated as a risk to their secret existence or exploited for their benefit. Throughout the season, Bo learns more about the Fae world and herself while she searches for information about her origins. Along the way, Bo also develops romantic relationships with both Dyson, a Light Fae wolf shapeshifter and police detective; and Lauren, a human doctor and scientist in servitude to the Light Fae.

### Season 2 (2011–12)

Bo faces personal challenges with Dyson after she finds out The Norn took his ability to feel passion for her in exchange for giving her the strength to defeat Aife in the season one finale; and with Lauren when their relationship became complicated after The Morrigan informed Bo in "It's Better to Burn Out Than Fae Away" that Lauren had a girlfriend. At the same time that she is coping with these turmoils, a villainous and evil ancient enemy of the Fae, the Garuda, is awakened and reappears with the intent to destroy the truce between Light and Dark Fae, and reignite the Great War between them. The new Ash, Lachlan, recruits Bo to be his champion in the battle against the Garuda and she agrees on the condition that he regard her as a partner, not as his servant. During this hectic time, Bo develops a no-strings-attached lustful relationship with Ryan Lambert, a Dark Fae Loki playboy that in "Fae-nted Love" became unwittingly thralled by her when, during energy-drawing healing sex, her blood came into contact with deep scratches she made on his back. Bo learns in "Into the Dark" that she is not only Trick's maternal granddaughter, but deduces that she has inherited some of his Blood Sage powers: if her blood comes into contact with someone's open wound, it can enslave and bind the recipient to her will (the same power that her mother, Aife, used to create male slaves). She uses her blood power to unite her team of Light and Dark in the final battle against the Garuda.

### Season 3 (2013)

With Fae society in upheaval, Bo finds herself facing further changes and challenges as former ally Hale becomes the acting Ash – trying to forge a new balance between Light and Dark by appointing a Valkyrie aligned with the Dark Fae, Tamsin, as Dyson's new detective partner. Meantime, Tamsin is a secret agent working for two separate clients: The Morrigan, who wants to build a case against Bo so that she can execute her; and as a mercenary for someone who wants to entrap Bo. Matters become complicated when Kenzi is kidnapped by a crazed Kitsune who assumes her identity and deliberately sows distrust in the relationships between Bo and those closest to her, just as Bo must prepare for and go through an evolutionary Fae rite of passage that forces her to explore her past and future. Danger escalates when a human scientist convinces a despondent Lauren to join him in conducting scientific research in his private laboratory – all the while deceptively concealing his intent to harness Fae genetics for himself with the use of her expertise. The third season culminates with Bo being engulfed by black smoke and disappearing into thin air, presumably whisked away by her mysterious and powerful biological father (who may be "The Wanderer" that recurred throughout the season's story arc).

### Season 4 (2013–14)

While Kenzi, Hale, and Dyson, are all living their lives, Bo is nowhere to be found. It's later realized that they simply forgot Bo, as someone was forcing them to. Massimo has been giving Kenzi temporary powers to appear Fae. Bo finally awakens to find herself on a train, and later jumps off. A group of Fae called the "Una Mens" are introduced. When she arrives home, it is discovered that while Bo herself did not consciously choose a side, her blood has chosen Dark. Tamsin is found reborn, as a little girl, and grows up with Kenzi as her pseudo-mom. Massimo steals from Bo and Kenzi in an attempt to convince Kenzi to pay him, and Bo figures out that he is not Fae, but human. He also kidnaps Tamsin to acquire her Valkyrie hair, and after being defeated by Bo, chases after the hair into a pit of lava, where at that point he is presumed to be dead. Many of Trick's secrets and past actions are revealed, including a tie to a past life of Tamsin's, and the fact that he used his blood to "erase" someone from existence. Tamsin discovers that by not taking the soul of a man named Rainer to Valhalla, she is part of the reason "The Wanderer" was created. Bo is able to get back on the train, where she finally meets Rainer, and brings him back to the Dal. Hale and Kenzi admit their feelings for each other. Lauren, who has been working with the Dark, somehow turns the Morrigan human. Kenzi's mother is introduced, and Hale attempts to propose. Massimo returns, and protecting Kenzi, Hale is killed. Kenzi tries to get revenge, but is stopped by Vex, who mentions that he is Massimo's guardian. Evony is revealed to be Massimo's mother, and gave him to Vex years ago when he was a boy. Bo learns that not only is her father coming, but that to close the portal, she will need to give her heart. That is revealed to be Kenzi.

### Season 5 (2014–15)
## Cast and characters
### Main cast

* Anna Silk as Bo Dennis: A Succubus, she can seduce and manipulate both humans and Fae with the touch of her skin; and has the power to absorb the life force (the "chi", or Qi) of humans and Fae by drawing it out through their mouths. She feeds and heals from oral chi intake, and chi absorbed from the sexual energy created with males or females. At first she could not feed without killing her sexual partners; but with Lauren's help Bo learned to control her sexual drive and chi-drawing powers so that she could have sex with both Fae and humans without injuring or killing them. She can only go a few days without feeding before the hunger overcomes her. Although Fae are stronger than humans and can better endure her feeding on them, they are not immune from being drained and Bo can render them comatose or kill them. She is best friends with Kenzi and is romantically involved with both Lauren and Dyson. When Lauren's life is threatened in "Death Didn't Become Him", a strange and extremely powerful alternate persona emerged from her, which drained the chi from multiple individuals at a distance of several meters, and she declared, "I can be more powerful than all other Fae. Everyone will kneel at my feet. There will be no more Dark and no more Light. There will be only me". In the first season, Bo finally met her birth mother, Aife, who is also a succubus. Towards the end of the second season, she learned that Trick is her maternal grandfather and that she is named after her grandmother, Isabeau. In the third season, Bo willingly entered into a monogamous relationship for the first time in her life when she asked Lauren to be with her. In the season five finale, she is finally reunited with Lauren as a couple.
* Kris Holden-Ried as Dyson: A wolf-shapeshifter and homicide detective in the human police force. He is 1,500 years old, very strong, possesses a sharp sense of smell, and is acutely knowledgeable about Fae politics. A member of the Light Fae, his true allegiance is to Trick rather than to the Ash. He fell in love with Bo while under orders from Trick to keep an eye on her, and is best friends with Hale, his Light Fae detective partner. In the Season 1 finale, he involuntarily sacrificed his love for Bo when he offered his wolf to the Norn in return for her giving Bo the strength to defeat her murderous and maniacal mother, Aife; but the Norn – who demanded his wolf the first time he asked a favor from her in "Brother Fae of the Wolves" – realized that his wolf is no longer what he valued most and took his love for Bo and his ability to love anyone else again instead, leaving him with the memory of their relationship but unable to feel passion for her. He made efforts to remain friends with Bo, which was initially awkward when Bo couldn't understand why he was distant (until Bo came to terms with his detachment and declared to Kenzi in "Can't See the Fae-Rest" that her relationship with Dyson is over). After reuniting with his old love, Ciara, their relationship was hampered by Dyson's reluctance to reveal his encounter with the Norn and what he had lost in the exchange; however, he eventually admitted to her that he offered his wolf but it had cost him his ability to love anyone. This ability is restored by the Norn after Kenzi threatened to mutilate and cut down her Sacred Tree in "Into the Dark". Although the idea that a wolf mates for life was ascribed to his relationship with Bo, in "End of a Line", the voodoo witch Laveau told Dyson that his "prison" (i.e. his love for Bo) was of his own making. In Season 5, it is revealed that Dyson has a son named Mark.
* Ksenia Solo as Mackenzie "Kenzi" Malikov: a human and Bo's best friend and sidekick, declared as Bo's "property" and "pet" to allow her to participate in Fae society. She suggested Bo use her neutrality and bewitching powers to her advantage to become a private investigator, with her as partner. Kenzi ran away from home at a young age and lived on the streets and underground for a long time before meeting Bo. A small-time criminal, somewhat compulsive pickpocket, and scam artist with a long rap sheet, she can speak Russian fluently and possesses excellent street-smarts. She prefers to be underestimated at first glance and tends to put up a facade of generic sidekick cowardice, silliness, and uselessness for camouflage and to keep herself out of harm's way. Her plentiful extended family, all local diaspora, provide a steady stream of shady connections, sources, services, and other "favors". She has a vast wardrobe of clothing and wigs to change her appearance at will. Despite their differences, she and Bo quickly became close friends, with Bo choosing humanity rather than Fae in "It's a Fae, Fae, Fae, Fae World", after Kenzi risked her life to find out where Bo had been taken by Dyson and Hale, and called out to Bo to help her break out of a spell she had been put under during the trial to determine her alignment with either the Light or Dark clan. Kenzi and Hale became friends, with her frequently teasing or assisting him; and by the third season she had also endeared herself to Vex. Her character is the show's comic relief and primary source of its trademark banter; and her thieving is one of the most regularly used special skillsets in the show.
* Zoie Palmer as Dr. Lauren Lewis (a.k.a. Karen Beattie): A Human owned by the Ash as his property, she serves as a doctor and scientist for the Light Fae. She was seduced by Bo during their first meeting and hence fell in love with her. She has extensive knowledge of the different types of Fae and their abilities. In the first season, she helped Bo learn how to control her powers so that she could have sex with both Fae and humans without hurting or killing them. It is later revealed that she had a human girlfriend, Nadia, who had fallen into a coma five years earlier after contracting a mysterious virus while in the Congo with her. In exchange for her servitude, the Ash offered Lauren access to the Light Fae's laboratory and resources to find a cure for Nadia's condition. Lauren learned from Lachlan in "Masks", that she was tricked by the previous Ash; he ordered a Dark Fae Shaman to curse Nadia into a coma to ensure that Lauren would do everything in her power to find an antidote to the fever that was killing Fae and then pulled her into the Light clan's fold. After Bo (unbeknownst to Lauren) removed the curse, Lauren and Nadia reunited; but their relationship was soon shattered when it was revealed that Nadia had been infected by the Garuda, and he could control her mind and body. Bo was forced to kill Nadia when she threatened Lauren's life. In "Caged Fae", Bo asked Lauren to be with her in a committed relationship; however, disappointed and feeling inadequate in satisfying Bo's succubus nature, Lauren told Bo that she needed a "break" from the relationship. Lauren walked away from servitude to The Ash and protection by the Light Fae afterwards. In "Adventures In Fae-bysitting", a part of Lauren's past is disclosed and we learned that her real name is Karen Beattie and that she is a fugitive wanted by the International Criminal Offences and Criminal Intelligence Bureau. In "Turn to Stone", Lauren revealed that she had a brother, they had been inseparable and decided together "to change the world", but their cause had turned into blowing up pipelines. She knew how to build pipe bombs and made them for her brother to position; however, one location was supposed to have been deserted but wasn't and eleven people were killed in the explosion. This led to her going on the run, changing her identity, and keep running ever since (by the details in the ICOCIB wanted poster, the incident occurred in 1998, when Lauren was 17 or 18 years old. She is also fluent in Spanish, French and Swahili). In "Those Who Wander", Lauren sabotaged Dr. Isaac Taft's plan to extract Dyson's DNA and transfer the cells into him so as to become a Wolf-Shapeshifter and turned Taft into a human/Cabbit hybrid instead, making him an easy kill for Dyson. She went missing thereafter. In "Let the Dark Times Roll", Bo and Lauren were reunited at a Dark Fae party. Lauren told Bo that she had fled for her life after the Una Mens began to kill humans. The Dark Fae (i.e. the Morrigan) came looking for her, offering refuge, protection, and freedom to come and go as she pleased in exchange for working for the clan. They remained friends, putting behind them their previous tensions. In "End of Faes", Bo asked Lauren to be together again, as a couple. In the season five finale, she is reunited with Bo as a couple.
* Rick Howland as Fitzpatrick "Trick" McCorrigan: The Bartender and owner of the only Fae pub in town, the Dal Riata, which is neutral ground where members of the Light and Dark Fae clans, can freely socialize and find sanctuary. Trick is very powerful; he is a Blood Sage and can alter fate by writing it with his blood. Once known as the Blood King, he forced the truce, and wrote the decrees that ended the war between the Light and Dark Fae, and is on equal terms with the Fae Elders. Compared to other Fae who have contempt for humans, he is tolerant and often fond of humans, even trading away his most prized possession to help save Kenzi's life in "Food for Thought". He respects Lauren and when necessary seeks her opinion and expertise with matters involving Fae. Trick is extremely reluctant to use his blood powers as it can have unforeseen consequences: in "Blood Lines", his writing a culmination where Aife's maternal instincts emerged and stopped her from hurting and killing Bo not only left him weakened and wounded from the loss of blood, but in "Lachlan's Gambit" he told Lachlan that it had awakened the Garuda. Near the end of the second season, he revealed to Bo that he is her maternal grandfather.
* K. C. Collins as Hale Santiago: A Siren and Dyson's colleague as another Light Fae detective secretly working in the human police force. He can pacify, control, and kill humans and Fae alike with his whistling; in addition, he can cure pain and heal wounds with it. He is the son of the leader of one of the three most powerful and wealthiest Light Fae families, the Clan Zamora, but despite his family's social status he makes his own way in life, preferring to create his own connections and leverage (although he allows Bo and Kenzi to use his high-class social contacts when they need to infiltrate an upper-crust Fae event). Hale became good friends with Kenzi, with an undercurrent of mutual attraction gradually developing between them. He helped save Kenzi's life using his siren's whistle to cauterize her wound in the Season 2 finale. In the third season, he became the acting Ash after Lachlan's death. After proposing to Kenzi in "End Of A Line", Hale died protecting her from Massimo.

## Development and production

On October 16, 2008, Canwest (Canwest Global Communications Corp.) announced that it had commissioned a pilot for Lost Girl from Prodigy Pictures. The script was to be written by Michelle Lovretta, who had previously been a writer for the Canadian television series Mutant X. Principal photography was completed in February 2009.
Canwest issued a press release on August 13, 2009, announcing that it had given the green-light for 13 episodes of Lost Girl to air on its specialty channel Showcase: "A drama loaded with mystery, romance and intrigue, Lost Girl focuses on the gorgeous and charismatic Bo – a Succubus with heart. While Succubi are inhuman women who seduce and feed off their human partner's sexual energy, Bo is not your average Succubus. Raised in secret by humans, Bo tries to survive in the human, modern world without giving in to her instinctive urge to kill. Refusing to embrace her supernatural clan and its strict regimes, Bo uses her feminine wiles – along with some help from her friends – to fight for the underdog. All the while, she is on a very personal mission to unlock the secrets of her origin and find her birth mother...Leading the Lost Girl cast is Anna Silk (Billable Hours, Being Erica) as Bo.

### Creator

In a 2011 interview for The Watercooler, Michelle Lovretta described her reaction to being asked to create Lost Girl:
   When Prodigy (our studio) asked me to create a show about some kind of bisexual superhero who uses sex as part of her arsenal, my first thought was "hell, yes!"...The challenge was to create a fun, sex-positive world that celebrates provocative cheesecake for everyone, without falling into base stereotypes or misogynistic (or misandristic) exploitation along the way...Bo has lots of sex, with men, women, humans, Fae, threesomes... and she's still our hero, still a good person worthy (and capable) of love, and that's a rare portrayal of female sexuality...It's also rare to have a female lead who is so honestly sexual, without judgment...I think the single element I will remain proudest of is just that we've been able to create and put out into the world a sex positive universe where a person's sexual orientation is unapologetically present and yet neither defines them as a character, nor the show as a whole...I felt it was crucial to also demonstrate that sex and romance aren't the only ways that Bo measures a relationship's worth, to give the show balance...Fans may have noticed that Kenzi clarified her hetero orientation at the end of ep 101...That line was necessary because...I was determined to protect their platonic-yet-epic BFF-ness, so I made sure it was written in as canon. Partly, this was to debunk the gay-panic cliche that bisexual people sexualize everyone, and are incapable of platonic friendship. But there was another, simpler and more personal reason: I think friendship is the fifth element...So, hidden in amongst all the romance and cleavage and threesomes, the Lost Girl Bo and Kenzi relationship is my own little love poem to all the BFFs out there who do it right.

### Showrunner

Series creator Michelle Lovretta teamed with industry veteran Peter Mohan to co-showrun Season 1. Lovretta and Mohan left (on good terms) after the first season to pursue other opportunities, and the Season 2 showrunner role was split between Lost Girl writer Jeremy Boxen and another industry veteran, Grant Rosenberg.
Emily Andras, who had been involved with the series as a writer and consulting producer since Season 1, became showrunner effective Season 3. In an interview for The Huffington Post after the announcement by Syfy that it had renewed the show for a third season, Andras described what direction she would like to see Lost Girl go in the future:
   Into a world where a bisexual protagonist is non-news. I'm so proud of the comedic ambitions of Lost Girl, that it's dedicated genre [fare] that doesn't take itself too seriously, but I also love exploring the shades of gray; the moral ambiguity of characters who may live forever and their relationships with mortals who will not.
In a December 2012 interview with the Writers Guild of Canada, Andras detailed the flow of the Lost Girl showrunner title, followed with a second interview in the guild's magazine, Canadian Screenwriter. In an interview with SpoilerTV, she addressed the fervor of the show's fandom. On March 10, 2013, after the Showcase broadcast of Fae-ge Against The Machine, Emily Andras participated in a special live question and answer session on Doccubus.com with fans of the show and of Bo & Lauren. In the Q&A, Andras also discussed the selection of Zoie Palmer for the role of Dr. Lauren Lewis, the theme of death, and the love triangle between "the wolf" and "the doctor". Starting with the premiere episode of Season 4, In Memoriam, Andras held a series of exclusive post-episode weekly interviews with The Loop (TV Guide.CA). She discussed the process of writing Lost Girl and her involvement with the series in an interview with the popular podcast fan site, Drinks at The Dal.
Michael Grassi, who joined the show as a writer and consulting producer for the fourth season, succeeded Emily Andras as showrunner for Season 5. (Andras moved into the position of executive consulting producer on the series.)

## Sexuality

The sexuality presented in Lost Girl is an important element of the show's narrative. The lead character, Bo, is a bisexual succubus that survives, thrives, and heals by feeding on the chi (life force) of male and female humans, and Fae — either by drawing it out through their mouths, or by absorbing the energy created from sexual contact with them. Casual sex is intrinsic and depictions of sexual encounters have also included threesomes.
Throughout the series, Bo has two primary romantic relationships: Dyson, a heterosexual shapeshifter Light Fae that transforms from wolf to human-like form; and Lauren, a lesbian human doctor and medical researcher who is a pledged servant of the leader of the Light clan. The relationships of Bo with Dyson and Bo with Lauren is referred to as the "Love Triangle".
As a succubus, however, Bo is unable to prevent the fundamental requirements of her nature from hindering emotional want. In Season 3, Bo asked Lauren to join her in a physically monogamous relationship, but her feeding needs ultimately made it unsustainable.
Other main characters in Lost Girl are heterosexual (Kenzi, Trick, Hale), while the sexual range of recurring characters varies. For example, the leader of the Dark Fae clan, The Morrigan, was seduced by Bo in Season 2, and Lauren in Season 4; the Dark mesmer, Vex, was shown initially as a BDSM submissive with a dominatrix and the first explicitly sexual disclosure about him was in a bisexual fantasy in Season 5. The Dark valkyrie, Tamsin, seduced Dyson in Season 4; and in Season 5 offered Bo her random one-night stand male after she had sex with him, followed by her commencing a sexual affair with Bo.
In the Lost Girl universe, sexuality is a natural, judgement-free affirmation of life. The sex-positive series has been praised by critics and fans for its seamless portrayal of amorous desire and groundbreaking representation of bisexuality — and for not labeling sexual orientations shown in episodes as straight, bisexual, lesbian, or gay.
In an interview with GayCalgary Magazine, Rachel Skarsten expressed what distinguished Lost Girl in its treatment of romantic relations:
   One of the things we pride ourselves in with Lost Girl is, it's not about this heterosexual couple, this homosexual couple – it's just about the relationship; about two people who love each other, and I think that is one of the things that makes our show really special.
A character's sexual identity in Lost Girl is precisely what audiences see without needing explanations in the storyline.

As of July 31, 2014, Lost Girl's Facebook page had 370,310 likes and its official Twitter had 66,000 followers, giving the series a large social media presence.

## Reception

Ratings for the 9 p.m. series premiere on September 12, 2010, was over "400,000 viewers (2+)" and "another 184,000 (2+)" for the episode rerun at 10:40 p.m., making Lost Girl the "highest-rated Canadian scripted series premiere of all time on Showcase."
In Canada, Rob Salem of the Toronto Star described the show as one that "definitely bears watching". Vladislav Tinchev, writer for the German site Serienjunkies wrote that the series would benefit from "revealing more background information about the represented world," rather than spend time on "clumsy action scenes". But Tinchev pointed out that "Lost Girl is not lost at all, and has immediately won the audience and entertains them well. And there is nothing wrong with that, because TV series need not be world-shaking events."
In anticipation of its United States premiere, Brian Lowry of Variety wrote: "At first glance, Lost Girl looks like another one of those Canadian imports picked up mostly for financial reasons. The pilot, however, proves unexpectedly fun—a sort of diluted version of True Blood... but the show has wit, style and an enticing lead in the leather-clad Anna Silk." Writing for The New York Times, Mike Hale said: "Like other fantasy-tinged shows on Syfy and USA, it offers the minor pleasures of formulaic fantasy and weekly puzzle solving, though in a cheaper-looking and less original package than usual...." In a post-premiere review for The Huffington Post, Mauren Ryan wrote: "No one can say there's been a dearth of genre-tinged programs on television in recent years. The vampire boom of the mid-aughts was followed by the zombie bonanza of the last couple of years; all in all, we're awash in various undead and otherworldly creatures...But one of the reasons Lost Girl has made such a big impression on me...is because the Syfy show does what so many genre programs fail to do these days: It has fun with its premise...But don't expect Lost Girl to be perfect: Bo's universe can seem constricted at times, the weekly clients and monsters aren't always interesting and occasionally the storytelling has abrupt moments. But my occasional complaints have been overwhelmed by my growing appreciation of what creator Michelle Lovretta has done with this light drama: She's created a Hero's Journey with a self-confident woman — a succubus, no less — at the center of it...Lovretta has done something subversively impressive with Lost Girl. She's built a whole show around the idea of a woman who is learning just how much she can or should take from others, and how much she can rely on herself."
The relationship between Bo and Lauren became popularly referred to as "Doccubus" after fans of the couple combined "Doctor" Lauren Lewis with Bo's "Succubus" species (i.e. Doc+cubus) to create the alias. The term was used with the show's publicity and by entertainment media and bloggers when referring to the pairing.
Episodes broadcast by Syfy in the United States have :90 seconds cut from their original 44:00 minutes to allow more time for commercial advertisements. In Season 2, the decision to edit an emotive scene between Bo and Lauren from "Scream a Little Dream" created controversy among LGBT fans of the show, resulting in the network being accused of insensitivity and censorship. Lost Girl producers responded to the backlash by issuing a public statement on the show's Facebook page explaining that the edits were done in-house, and not by Syfy, for "timing and not content." As noted by Dorothy Snarker writing for AfterEllen: "With so little representation of gay relationships on TV, every little touch matters." After this experience, beginning with Season 3, the original opening title sequence accompanied by the Lost Girl Theme song was replaced with opening credits superimposed over footage of the first scene, sparing :30 seconds from being cut from the episodes for Syfy (U.S.).
In a 2012 report by TiVo of television programs watched at bedtime, Lost Girl was rated one of the top ten, most watched shows.
In a Slate magazine 2012 year-end list of 15 favorite television shows that are a pleasure to watch, Lost Girl (on Syfy) was named "Number 1" on the list, and hailed as "Sexy, snarky, and Canadian."
"Bo and Lauren" was chosen Top TV Couple of 2013 by E! Online (E! Entertainment Television), with its competition in the annual popularity contest compared to a "David versus Goliath".
On February 14, 2013, a CNN (Cable News Network) segment of its 35 favorite television couples, past and present, named "Bo and Lauren" couple "Number 9" in the list.
"Lauren Lewis" was chosen "Number 1" by AfterEllen in its November 2013 survey of The Top 25 Lesbian/Bi Characters on TV (Right Now). "Bo" was named "Number 7" in the list.
In an exclusive selection of the best Canadian television shows of 2013, Lost Girl was rated "Number 6" by some of Canada's top critics and television editors in Canada's Best in Show by TV Guide (Canada).
HuffPost Canada TV ranked Lost Girl as the "Number 4" television show in its Best Canadian TV Of 2013.
In the annual AfterEllen Visibility Awards, Lost Girl, Lauren Lewis, and Zoie Palmer won the categories in which they were candidates for year 2013.
At the 2014 Canadian Screen Awards, Lost Girl won the Fan Choice Award for Favourite Canadian Show and Zoie Palmer won the Fan Choice Award for Favourite Canadian Screen Star. In 2015, Anna Silk received the Fan Choice Award for Favourite Canadian Screen Star by the Academy of Canadian Cinema & Television.
"Bo Dennis" was named "Number 92" in the list of the top 100 Best Sci-Fi Characters of All Time by the British Film Institute.
