Buffy's request, takes Dawn out of Sunnydale to safety. Also, Principal Wood returns to join the cause and finally accepts Spike. In the series finale, Dawn adamantly returns to help fight against the First. As she does so, Angel leaves Los Angeles and returns to Sunnydale with an amulet (given to him by Wolfram & Hart), which Buffy gives to Spike. Buffy finally kills Caleb by cutting him in half with the scythe. While Caleb is dead, they make their move to thwart The First's plans once and for all. The Potentials descend into the Hellmouth to fight an army of Turok-Han, while the other Scoobies hold off the few Turok-Han that escape into the halls of Sunnydale High. Willow uses a spell that activates all the Potential Slayers, granting them some Slayer powers. Anya is killed in the fight, along with some of the new Slayers. Fearing she is done for, The First returns to taunt Buffy, saying her fight is in vain. Refusing to let the world be destroyed, Buffy and her allies dig deep and begin to gain the upper hand. Spike's amulet channels the power of the sun and kills all of the Turok-Han in the Hellmouth, but Spike himself is also consumed and he sacrifices himself to defeat the enemy. Buffy tells Spike she loves him; he tells her to run. The Hellmouth collapses, and the resulting crater swallows all of Sunnydale. The survivors of the battle escape on a school bus, which Buffy catches up to after saying goodbye to Spike. In the last scene of the series, the survivors gather on the rim of Sunnydale's crater. The Scoobies and new Slayers tend to the wounded. Xander mourns Anya's death and is consoled by Andrew. Dawn asks what their next move is and Buffy smiles.
