Plot
It is Christmas in Sunnydale and Angel is haunted with dreams of the people he murdered over the years as Angelus. Visions of his past victims, including Jenny Calendar, appear to him. When Buffy starts getting dragged into his memory-nightmares, experiencing Angel's dreams also, they realize something unnatural is happening. Angel's visions develop and try to get him to kill Buffy, saying that he will be released from the pain if he does so. Angel cannot bring himself to do this, so instead he opts to kill himself by standing on a hill and waiting for the sun to come up.
Buffy and Giles figure out that the First Evil has been driving Angel insane. Buffy finds the Bringers and pummels them. After the First appears to her, informing her that she cannot possibly fight it, and that Angel is about to be destroyed by the dawn's light, she runs to his mansion to stop him. Buffy, who invited and ordered Faith to watch Joyce, finds Angel atop the hill behind the mansion, awaiting sunrise. However, the heatwave from which Sunnydale has been suffering abruptly ends and the first flakes of snow start to fall, which Angel takes as a sign he was brought back for a purpose. With the weather report saying the sun should not be expected to be seen at all that day, Buffy and Angel take a walk through the town.
Meanwhile, Oz tells Willow that he is willing to give their relationship another chance while Cordelia is not as forgiving and resumes her previously hostile ways towards the Scooby gang. Oz goes to Willow's house to watch videos only to find her dressed up and playing Barry White's music, intending to sleep with him. Oz appreciates the gesture, but explains to Willow that he wants their first time to be special rather than just a way for her to try to make things up to him.
