Now that Buffy is dead and buried, what happens next? There apparently is going to be a sixth season of BtVS on UPN, so I assume that Joss Whedon will resurrect her or retitle the show, “The Scooby Gang.”
Looking back on the whole season, one can see that Buffy’s death was foreshadowed: in the episode where spike recounts killing two previous Slayers, he mentions that they both had a death wish; Buffy had mentioned in several episodes how hopeless her life was; and, of course, the First Slayer had said, “Death is your gift.”
In aditon, an interview with Marc Blucas I read said that Riley would be back for the season ender, so where was he?
