Question: In what episode was the character in "Buffy the Vampire Slayer" who was also portrayed by the actor who played John Hawkes in "Underground" introduced?
Context: Faith is a fictional character created by Joss Whedon for the television series "Buffy the Vampire Slayer".  Played by actress Eliza Dushku, Faith was introduced in the third season of "Buffy" and was a focus of that season's overarching plot.  She returned for shorter story arcs on "Buffy" and its spin-off, "Angel".  The character's story is continued in the comic book series "Buffy the Vampire Slayer Season Eight", and she also appears in apocryphal material such as other comic books and novels.  Faith was set to receive her own spin-off television series after the final season of "Buffy", but Eliza Dushku declined the offer, and the series was never made.  The character later co-stars in the 25-issue comic book "Angel & Faith" beginning in August 2011 under the banner of "Buffy the Vampire Slayer Season Nine", the story taking place mostly in London and the surrounding area.  Seven years after the character's creation, Whedon granted her the surname Lehane for a role-playing game and subsequent material.  The last issue of "Season Eight" was the first source officially confirmed to be canon that referred to Faith by her full name. Buffy the Vampire Slayer is an American franchise which spans several media and genres.  It began in 1992 with the film "Buffy the Vampire Slayer", written by Joss Whedon and directed by Fran Rubel Kuzui, and was resurrected as the television series, "Buffy the Vampire Slayer" in 1997.  The show's popularity caused it to spawn a multitude of Expanded Universe tie-in material such as comic books, novels, and video games, as well as a spin-off program entitled "Angel".  In 2007, four years after the television series' seventh and final season, "Buffy the Vampire Slayer" was officially continued in the comic book "Season Eight".  The following is a list of minor recurring characters who appear in the franchise. Riley Finn is a fictional character created by Joss Whedon for the television series "Buffy the Vampire Slayer".  Portrayed by Marc Blucas, Riley was introduced in the 1999 season four premiere episode, "The Freshman", and Blucas was part of the series credited cast for the second part of season four and the first part of season five.  Most notably, Riley is one of three long-term romantic interests for series' heroine Buffy Summers (Sarah Michelle Gellar). Buffy Anne Summers is the titular character from the "Buffy the Vampire Slayer" franchise.  She first appeared in the 1992 film "Buffy the Vampire Slayer" before going on to appear in the television series and subsequent comic book of the same name.  The character has also appeared in the spin-off series "Angel", as well as numerous non-canon expanded universe material, such as novels, comics, and video games.  Buffy was portrayed by Kristy Swanson in the film, and later by Sarah Michelle Gellar in the television series.  Giselle Loren has lent her voice to the character in both the "Buffy" video games and an unproduced animated series, while Kelly Albanese lent her voice to the character in the "Buffy the Vampire Slayer Season Eight" motion comics. Dawn Summers is a fictional character created by Joss Whedon and introduced by Marti Noxon and David Fury on the television series "Buffy the Vampire Slayer", portrayed by Michelle Trachtenberg.  She made her debut in the premiere episode of the show's fifth season and subsequently appeared in every episode of its remaining three seasons.  Within the series, Dawn is the little sister of main character Buffy Summers (Sarah Michelle Gellar), a girl chosen by fate to be a vampire Slayer.  Whedon introduced Dawn to the series because he wanted to introduce a character with whom Buffy could have an intensely emotional non-romantic relationship. Angel is a fictional character created by Joss Whedon and David Greenwalt for the American television programs "Buffy the Vampire Slayer" and its spin-off series "Angel".  The character is portrayed by actor David Boreanaz.  As introduced in "Buffy" in 1997, Angel is a love interest for heroine Buffy Summers (Sarah Michelle Gellar), a young woman whose destiny as "the Slayer" is to fight the forces of evil, such as vampires and demons.  However, their relationship is complicated by the fact that Angel is himself a vampire cursed with remorse and a human soul, which motivates him to assist Buffy in her duties as Slayer.  The character's popularity led to the production of the spin-off "Angel", which follows the character's struggle towards redemption after moving to Los Angeles.  In addition to the two television series, the character appears in the comic book continuations of both series, as well as much other expanded universe literature.  Angel appears in the most television episodes of all the characters of both "Buffy the Vampire Slayer" and "Angel", appearing in 167 episodes (57 in "Buffy" and all 110 in "Angel"). Drusilla, or Dru, is a fictional character created by Joss Whedon and David Greenwalt for the American television series, "Buffy the Vampire Slayer" and "Angel".  The character is portrayed by American actress Juliet Landau.  Drusilla is introduced alongside her lover Spike (James Marsters) in the second season of "Buffy the Vampire Slayer" to serve as new antagonists to the series' heroine, vampire Slayer Buffy Summers (Sarah Michelle Gellar) and alongside Darla (Julie Benz) and Wolfram & Hart as the main antagonist of the second season of Angel.  In contrast to the series' previous central villain, the ancient and ceremonious Master (Mark Metcalf), Spike and Dru were introduced as a more unconventional but equally dangerous pair of vampires. Buffy the Vampire Slayer: Chaos Bleeds is a 2003 video game and the fourth of the "Buffy the Vampire Slayer" franchise, and the only multiplatform game.  It was the first to allow players to control characters other than Buffy Summers and feature a fully developed multiplayer mode; additional players had a limited ability to interact in a hidden debugging mode in the previous game, "Buffy the Vampire Slayer". Buffy the Vampire Slayer: Willow & Tara is a trade paperback anthology collection published by Dark Horse Comics in 2002 and based on the television series "Buffy the Vampire Slayer".  The volume collects three issues focusing on Willow Rosenberg and Tara Maclay: "Buffy the Vampire Slayer: Willow & Tara - Wannablessedbe", originally published in 2001 as a one issue special, and "Buffy the Vampire Slayer: Willow & Tara - Wilderness", originally published in 2002 as a two issue limited series.  It also adds a story from an "extra" issue.
