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".
Forever (Buffy the Vampire Slayer)
The next day, a group of people gather at a cemetery for Joyce's funeral. Dawn leaves with Tara and Willow while Buffy remains at the grave. Hours later, after the sun has set, Angel appears beside her. Inconsolable regarding the loss of her mother, Dawn reveals to Tara and Willow her intent to perform a resurrection spell. After making love, Anya tells Xander how special it is to be able to create life, and how sex has become much more meaningful. Tara tries to convince Dawn that magic can't be used to alter the natural order of things, such as life and death, and tells her that Wiccans took an oath disallowing resurrection. In the graveyard, Angel does his best to comfort Buffy when she worries how she will continue without Joyce's strength, and if there was any chance she could have saved her mother. Angel offers to stay in town for as long as she needs him, and Buffy asks him to stay with her forever. The two kiss sweetly but pull away, knowing nothing more can happen. Buffy expresses her gratitude, and he stays with her until the sun rises. Ben encounters Jinx, saying that he will not help Glory and he is tired of her games, but accidentally makes a comment that leads Jinx to conclude that the Key is human. Not wanting Glory to learn this fact, Ben stabs the minion with his own knife.
