Buffy the Vampire Slayer: What's My Line? Part 2 (1997)

Synopsis
Confused about how there could be another Slayer, Buffy (Sarah Michelle Gellar) figures out that when she briefly died (see "Prophecy Girl") -- Kendra was activated as Slayer. Buffy is jealous at first of Kendra's dedication to her duties, but soon discovers that Kendra really doesn't care about helping people as much as she does. Meanwhile, Angel (David Boreanaz) is rescued from his cage by Willy the Bartender (Saverio Guerra) only to be handed over to Spike (James Marsters). Apparently, Spike needs Drusilla's (Juliet Landau) sire -- Angel -- to complete the ritual to restore Drusilla's health. Realizing this, Kendra and Buffy beat the location of the ritual out of Willy. They manage to end the ceremony before Angel is dead, but not before all of Drusilla's powers have been restored. Spike is injured in the fight, and subsequently the couple switches roles, with Drusilla having to care for Spike. This episode marks the actual beginning of Xander (Nicholas Brendon) and Cordelia's (Charisma Carpenter) relationship, as they argue, and then kiss, while trapped in a basement. ~ Matt Collar, All Movie Guide
