Angel (season 1)
At the end of the third season of "Buffy", the 242-year-old, re-ensouled vampire Angel left Sunnydale to give teenage Slayer Buffy Summers the chance to live a normal life. Angel is now living in the big city of Los Angeles. With Buffy gone Angel is now completely cut off from society, every day getting closer and closer to giving in to his vampiric hunger. It's not until he befriends the half demon and fellow Irishman Doyle, who is sent visions of people in trouble by The Powers That Be, and fellow Sunnydale resident Cordelia Chase, who grounds Angel's life in the humanity around him, that he truly begins to take charge of his life and seek atonement for his past sins. He sets up his own detective agency, Angel Investigations and begins to "help the helpless".
Cordelia Chase
After three seasons on "Buffy", Cordelia left the series to move over to star in "Angel", a spin-off series focusing on Buffy's vampire ex-lover Angel (David Boreanaz). The first season of "Angel" sees Cordelia move to Los Angeles, in the hopes of escaping her new-found poverty by becoming an actress. After Angel saves her life in the series pilot, Cordelia helps him found the supernatural detective agency Angel Investigations, working in an administrative position. She also becomes close to half-demon co-worker Doyle (Glenn Quinn), but their budding romance is ended by his death nine episodes into the series. Before dying in the episode "Hero", Doyle passes his ability to see people in distress over to Cordelia when he kisses her. Although she initially views the visions as a curse, in the season one finale, a demon causes Cordelia's visions to overwhelm her—causing her to experience worldwide pain—and upon her recovery she vows to help those in need. In season two's "Reunion", Cordelia and the other staff at Angel Investigations are fired by Angel, who is becoming increasingly obsessed with bringing down the evil law firm Wolfram & Hart. Cordelia joins Wesley and Charles Gunn (J. August Richards) in re-forming the agency on their own. Angel and Cordelia eventually reconcile in the episode "Epiphany". As her acting career continues to flounder, Cordelia is sucked into and made princess of a medieval hell dimension called Pylea in the season two episode "Over the Rainbow". When presented with the opportunity to pass her visions over to a champion named the Groosalugg (Mark Lutz), Cordelia refuses and returns to L.A. with her friends in the season two finale.
