What happens in season 6 episode 1 of Buffy the vampire slayer?

Answer 1

SPOILER ALERT

Buffy's dead and they're using Buffybot to fool Vampires and demons. Willow, Xander, Anya, and Tara are planning to raise Buffy, which is doable because she was killed by a mystic force, not a natural one. Giles leaves hours before they attempt to raise her because he, Dawn, and Spike are completely clueless of the fact this is going to happen.

Buffybot screws up and gives a vamp the slip that she's a robot and the vamp escapes and tells his demon friends, who raid Sunnydale, causing a lot of destruction.

Willow can't be interrupted during the spell, but Buffybot automatically tracks Willow when she's injured. She gets injured by the demons who follow her to Willow, eventually disrupting Willow, and causing Buffy to be brought back, but in the same place they left her. In her coffin. She digs her way out and eventually goes to the tower where she'd died in the last episode of season 5. Dawn finds her there and she asks, "Is this hell?" right before she and Dawn get off the tower quickly before it collapses.

You later find she asks this, because compared to the Heaven she was in while she was dead, this world really seemed like hell.
