Plot
Tara and Dawn wake on the couch and find that neither Buffy nor Willow returned home the night before. Buffy wakes up naked with Spike to find that the building around them fell down as she remembers what they did. Spike tempts Buffy as she tries to leave and reminds her of everything they did the night before. Disgusted by their actions, Buffy leaves, threatening to kill Spike if he tells anyone about what happened.
Amy returns home with Willow and rambles about Willow's amazing magic – in front of Tara and Dawn. Tara leaves as Buffy returns, and after a chat, Amy leaves and Buffy and Willow go to bed after their long nights. Willow tries to shut the drapes of her room with magic, but she is too exhausted to manage it. Anya reads bridal magazines instead of researching the freezing demon. Xander gets frustrated, finding bridal magazines in every research book he checks. At the magic shop, Xander, Anya and Buffy discuss Willow's behavior and Buffy comes to Willow's defense.
Amy suggests that she and Willow visit a warlock, Rack, who can give them great spells that last without any recovery time. The house is cloaked and filled with the magically addicted, seeking a fix. Rack takes a "tour" of Willow's mind before giving her what she came for. Amy spins about the room wildly as Willow hangs out on the ceiling, seeing spots and weird images. The next morning, Willow wakes in her own room and cries in the shower. She manipulates some of Tara's clothes to form an invisible body and curls up against it.
