Xander says to himself he's had enough excitement for one evening. How wacky that he says that now! Groan. Nearby, Faith is fighting one of the Sisterhood. They seem well matched. The demon throws Faith into a fence. Xander comes along and hits the demon with his car. Unfazed, the demon gets up. Xander yells at Faith to get in, which she does. They escape to her motel. She says the demon dislocated her shoulder. "Hold me," she says to Xander. He doesn't know quite what to make of that. He tries to embrace her, but she moves his hand to her shoulder and pushes against him, snapping her shoulder back into place. She says she's wound up, and she starts to rub her hand over Xander's chest. "A fight like that, and no kill. I'm about ready to pop." Mrow. She asks if he's up for it, and he predictably says he's "up," but that he's never been "up with people" before. Heh. They mack. She throws him on the bed, and promises she'll "steer him around the curves." Okay, that was really cheesy. She's still hot, though. Xander: "Did I mention that I'm having a very strange night?" Faith pounces.
Reflected in the TV, we see them going at it, covered by a sheet. Afterward, they lie in bed, and he caresses her. Cut to Faith shoving him, half-clothed, out the door. With a smile, she says, "That was great. I gotta shower." That was a little over the top, but I've done similar things, so I can't really say anything. Xander looks appropriately shell-shocked.
Library. Short version: Giles and Willow tranquilize Oz so they can move him to a safer location.
Xander, now dressed, gets in his car. He inspects the supplies the Deadas left in the car, and realizes that "baking a cake" is a euphemism for building a bomb. He drives back to the hardware store, but they're gone. He decides to find Buffy, but not before saying to himself: "I can't believe I had sex." You and me both, brother. He says, "Buffy'll know what to do."
