Walking across the cemetery toward the exit, Angel ran up to Buffy. She looked at him, and started to speak, her voice sounding more pained than usual. "Shawn's dead. Spike killed him. I stake Spike. Come on, we have to tell the others what happened." She held his hand, and to an onlooker, they were a normal couple. In reality, they were a vampire and a Slayer about to deliver horrible news to the ones they loved.
When Buffy and Angel walked in to the library, they saw Willow holding a glass of water, and Giles sitting up. Buffy ran over and hugged him, remembering her slayer strength when Giles grunted. "Oh! Sorry!" She looked at everyone then settled on Willow. "But Will, he was dead, we saw it. Why is he alive?" Seeing the look on Giles face, she stammered out, "Not that I'm not happy about it, 'cause I am."
Giles stood up and looked around the room. "Well as glad as you all are to have me back, the answer to your question is that-."
"Just a side effect of the spell." Everyone looked toward Oz, surprised that he had spoken up and interrupted Giles.
"Thank you, Oz." Willow said, and looked nervously at Giles. "No offense, but you tend to act British, and never get around to the answer." Looking at everyone else she said, "You see, Giles had to die to be released, but now he's not dead anymore, which we're all happy about."
Angel walked up behind Buffy and tapped her on the shoulder. "Uh, Buffy? Maybe you should tell them about Spike now."
