Louise Gilbert

Louise "Lou" Gilbert-Salvatore is one of the main female protagonist of The Tangled Diaries. At the beginning of the series, Louise appears to be not exactly human, then it was later revealed she is a seer and a Petrova doppelgänger. In Before Sunset, she becomes a vampire.
Louise had been struggling to live a normal life ever since her adoptive parents, Miranda and Grayson Gilbert, died in a car accident when she was seventeen years old. Her life changed drastically as she and her friends get caught up in the supernatural world that surrounds them and are forced to face powerful supernatural enemies.
Louise is described as a star student. She is popular, sporty, smart, compassionate, empathetic, caring and friendly.
Louise is best friends with Bonnie Bennett; her sister, Elena Gilbert; Caroline Forbes; her husband, Damon Salvatore; and her brother-in-law, Stefan Salvatore. Her actions and beliefs throughout the series have been most influenced by her on-and-off romantic relationship with Damon Salvatore as well as by her antagonistic relationship with Viviana Petrova.
In Season One, Louise is still coping with her parents' death when she meets the Salvatore brothers. However, not long after that, Louise discovers that both Damon and his brother, Stefan, are vampires. Louise and Damon formed a complicated friendship and she found herself growing attracted to him, despite his dangerous side. And then when she found out about his obsession with Vivienne - the woman who turned the Damon into a vampire in 1864, and to whom Louise bears a striking physical resemblance - it makes her even more worried about her growing feelings. In the process, Louise discovers a shocking truth - she was adopted, and her real parents are John Gilbert, her "uncle", and Isobel Flemming, Alaric's wife.
In Season Two, Louise learns that she is Vivienne's doppelgänger, which explains their identical appearance. She also finds out she is a seer. Because of this, an Original Vampire, Klaus, wants to use her in a sacrifice to break an ancient curse. Her biological father, John, sacrificed his own life to keep Louise alive and human. However, Klaus killed Louise's aunt Jenna, after turning her into a vampire, leaving Elena and Jeremy her only last two blood relative left alive. In this season Damon and Louise become an official couple.

== Personality ==
=== Seer ===
As a human, she's the sociable and outgoing girl. She's compassionate, nice, caring, beautiful but she can be mean, fierce, and deadly when she needs to be. She is also athletic and a cheerleader. She is brave and self-sacrificing, though much of her willingness to save others seems to come from survivor's guilt over her parent's death. Louise is fiercely loyal to her loved ones. She has a heartfelt respect for the basic concept of one's free will.
=== Vampire ===
<tabber>
|-|With Humanity=
As a vampire, Louise's personality is amplified. Louise wants to live on blood bags, in an attempt to avoid hurting someone. However, she is unable to keep down human blood from a blood bag or vampire blood. Due to her overwhelming hunger she kills someone, in The Rager. It is discovered that her inability to consume other sources of blood was unintentionally due to her sire bond to Klaus, and eventually begins to live on a diet of blood bags from a human blood bank. Now that Louise is a vampire, her feelings are magnified, including her feelings for Klaus, and they're much harder for her to ignore and push aside.
She also struggles with magnified grief from the loss of so many family members, and anger towards those who put her remaining friends and family in danger. Louise has now accepted being a vampire, she fairly happy with the fact she gets to spend forever with her boyfriend Damon. 
|-|Without Humanity=
When her brother Jeremy dies during their failed attempt at obtaining the cure, Louise doesn't show much reaction, distracting herself by helping Damon find Bonnie on the island. While Elena's having a break down with coming to the terms that Jeremy is gone, Louise runs off in tears. Klaus later finds her, trying to calm her down and he eventually telling her to "turn it off." to which she complies.
As well as losing her humanity, she's lost her modesty. She doesn't care about the rules. Louise always lived by her set of rules, what she thought was right and wrong, and now it's like she's thrown all the rules to the wind and she just does whatever she wants to do. She warns Stefan that he tries to ruin her fun, shell make him regret it. This she does when she later forces her sister, Elena to turn off her emotions as well, therefore leaving Stefan to deal with his emotionless girlfriend and Louise is free to have more fun.
</tabber>
== Physical Appearance ==
Being fraternal twins, Louise and Elena although not identical do share a similar resemblance. Physically, Louise is very beautiful and attractive young woman with an oval face, light olive complexion, almond-shaped brown eyes which are often described as doe-eyes and dark brown hair. . Her height is 5'6"(168 cm), and she has a slim, slightly athletic physique. Louise has a uncanny resemblance to her ancestor and doppelganger, Vivienne Pierce, who often poses as Louise in order to trick others. However, even though Louise and Vivienne look exactly the same in terms of physical appearance, there are some slight differences between the two in terms of fashion and style, and especially personality. 
In terms of fashion sense she's much more casual, sporty and "girl next door" and
doesn't wear a lot of make up or favour fashionable clothing unless attending a formal event. Louise favours wearing dark blue jeans with t-shirts of various colours and Converse sneakers. Louise primarily wears fashionable clothing or dresses up for special occasions or formal events. Vivienne's fashion sense or style, on the other hand, is much more high maintenance, expensive and trendy. Another distinct difference between Louise and Vivienne physical appearance is that Louise always wears her hair straight with a middle part in which Vivienne doesn't like, while she wears her hair curly. Louise wears a necklace containing the herb vervain in it ; it was given to her by Stefan to protect her from compulsion.
As a newly turned vampire, Louise wears a daylight ring picked out by Damon in order to protect her from the sunlight. She has a slightly more grown up look, while she still wears her usual jeans and t-shirts, she usually trades them for dresses and boots. She also dips into her jewellery box more often. After she abandons her humanity, she becomes more womanly in the way she looks. While in New York, she cuts her hair shorter to her shoulders for two reasons; one, she wanted a changed and two, so there was a more clearer way to tell her and Vivienne apart.
In later seasons, Louise starts to experiment more with her wardrobe. She wears more skinny jeans, boots, more blouses, leather jackers and short skirts/shorts, dresses and more revealing tops. She plunges more into her jewellery box.
As usual she wears her hair straight in a middle part but wears it curly more often than she usually did.
== Powers and Abilities ==
<tabber>
|-|Seer=Louise has shown to use these powers:
* Precognition: The power to perceive information about future places or events before they happen. This ability is usually used subconsciously or in a dream as a nightmare but they don't usually occur that often and are usually quite vague.
* Retrocognition: The power to discern events of the past. Louise has had this power from as early as 2010. It is usually triggered when she touches something or someone or is in a place with psychic energy.
* Clairvoyance: The power to gain direct visual information of the present. Louise mostly used this in season three when she spent the summer with Klaus locating werewolves.
* Astral Premonition: The power to receive visions of the past or future by astral projection. This allows the user to experience the vision first hand. Louise first experienced this in 'Let the Right One In' while looking for Stefan. She describes it as feeling 'real'.
* Intuition: Louise seemed to know when something bad is about to happen and sometimes predicts things, like when she predicted Caroline was going to win Miss Mystic Falls.
She possesses fighting abilities to defend herself against vampires. Louise is also a Doppelgänger/Seer which means her blood in an unlimited (while she's alive) source of power for witches and siphoners as well. 
|-|Vampire=Louise possessed all the standard powers and abilities of a non-original vampire.

== Weaknesses ==
== Relationships ==
===Miranda Salvatore===
Main Article: Miranda and Louise
:"I love you more than life itself."
: — Louise to her daughter, Miranda
Miranda is Louise's only daughter and child with her husband, Damon Salvatore.
===Damon Salvatore===
Main Article: Damon and Louise
:"I love you too. I don't know or even sure when I started loving you - you crept up on me. I was never suppose to fall in love with you, but I couldn't stop and that scared me. I'm sorry I didn't say it sooner."
: — Louise to Damon in Katerina & Viviana
Their close relationship isn't one of the most shocking things in the world. She's the doppelgänger of his old love Vivienne Pierce, so it isn't odd that he immediately felt a close relationship with her. Although Damon and Louise often bicker and don't get along, Louise began to slowly warm up to him as she got to know him, befriending him in the process. Due to Damon's constant immoral and impulsive behaviour, Louise tried to keep her distance with failure. They soon fall for each other. Damon is seen to be extremely selfish when it comes to Louise, willing to put the life of Louise's before anyone else's, including Louise's loved ones.

During Season Two, Damon tells Louise he's inlove with her and Louise, no longer fighting the feelings she has for Damon, admits she loves him too. That night, Damon and Louise made love for the first time and became a real couple.  During their romance, Damon has never given any indication that Louise would "lose" him, under any circumstances really. Quite the opposite, he promised never to leave her. The passion they share is hard to define. Damon once again had the opportunity to prove his worth and show Louise his humanity. She brings out the good side of him — that he doesn't have to kill for fun and drink blood from innocent people. Throughout, Season Three and Four, due to Klaus, they maintain a rocky relationship but they manage to overcome anything. At the start of Season Five, having had the perfect summer together they were determined to make their long distance relationship work while she attended college. Their happiness was short-lived, however, as Louise and Damon's relationship was repeatedly assailed by a seemingly endless number of difficulties. Despite all this and having numerous arguments, separations, breakups and reconciliations, they never denied their love for each other. At the end of Season Five, Damon proposes to Louise to assure her of his promise to return to her from the other side.
