In part two of the Buffy/Angel crossover, "Past Lives," Cordelia and Wesley are both in the hospital and Angel is on the run. And the mysterious demon hunter continues her vendetta against him. Meanwhile, monsters are fleeing the carnage in L.A. and seeking refuge in Sunnydale, where they're being dealt with by the Slayer. Buffy, Giles, and the gang learn about the havoc, and Buffy determines that she must go to Angel's side to lend a hand; a decision that does not sit at all well with Buffy's vampire-hunting boyfriend, Riley.
