Buffy: Angel was cured.
Giles: I'm sorry?
Buffy: When I killed him, Angel was cured. [to Willow] Your spell worked at the last minute, Will. I was about to take him out, and, um, something went through him, and he was Angel again. He-he didn't remember anything that he'd done. He just held me. Um, but i-it was, it was too late, and I, I had to. So I-I told him that I loved him, I kissed him, and I killed him.
