Buffy was The WB's first double hitter — a breakout and a cult hit, teen-centric and adult-oriented. Crucial Buffy-mythos events occurred in this 1998 episode, ''Becoming, Part 2,'' as Sarah Michelle Gellar's vamp killer was compelled to slay her great love, Angel, to save the world. At that point, Angel (David Boreanaz) was switching in and out of his evil alter ego, Angelus, representing death and destruction as much as he did allure and romance. At the operatic climax, Buffy and Angel kissed, and then she stabbed him in the chest. Also in this Joss Whedon-written masterwork: Buffy's mother first discovered her daughter is a slayer, and Xander told a pre-gay Willow that he loves her. This season ender concluded with Buffy leaving Sunnydale on a bus. You know you're in bad shape when you're a supernatural hero using the most depressing form of cross-continental transportation.
