Here's a summary of the episode "Crush"
The Bronze has reopened (after the troll bashing from Triangle) and the gang are there dancing, except for Buffy who is alone. Spike sits with her, to her surprise. He feels since they fought Glory together (in Blood Ties), she could cut him a bit of slack. But nobody does and he walks away angry. Xander notices he stole Xander's change. Willow is still getting headaches from the teleportation spell she used in Blood Ties. Buffy sees Ben and goes to talk to him. She thanks him for helping Dawn, he clearly is worried what she may know. Xander confronts Spike who ignores him but is upset at seeing Buffy with Ben. At the train station, a train arrives but nobody gets off. The station master walks aboard and sees a car full of dead people. He flees but is caught by an unseen creature on the train and killed.
Buffy arrives home where she finds Joyce, Dawn, and Giles. Joyce says she wasn't feeling safe with Buffy gone, then backpedals and says of course she felt safe with Giles there. Giles goes to leave and Buffy speaks privately to him about Dawn. He says they should treat her normally and Buffy immediately yells at Dawn for stealing her sweater which Dawn denies. We cut to Spike fondling the missing sweater. Harmony walks in looking for sex, but he's not in the mood. She suggests a game. He has her dress like the slayer and pretend to be hunting him, this gets him sexually excited.
Willow, Tara, and Buffy are in school arguing over the Hunchback of Notre Dame. Buffy sees a headline in the paper about the incident on the train and realizes it was a vampire. At his crypt, Spike finds Dawn. She won't leave and soon Spike is pumping her for information about how Buffy feels about him. Buffy gets home to find Dawn missing and goes to look for her. Spike is telling Dawn a story about one of his killings of a family. Buffy bursts in just as he is about to describe how he killed a little girl. She was coming to get Spike to help her and is outraged to find Dawn there. Dawn wants to hear the rest of the story and Spike bowdlerizes it, saying he gave the girl to a good family who were really nice to her. On the way home, Buffy is lecturing Dawn and wonders whether she has a crush on Spike. Dawn says Spike is in love with Buffy.
Buffy and Xander search the train car for clues. Buffy asks him about Spike and he finds the whole thing funny. They don't find anything, but we see a doll suggesting Dru is in town. Buffy comes home to find Joyce telling a story to Dawn and Spike with Spike pretending to be amused. He came to apologize about the night before and he tells Buffy he has a lead on the vampires who killed the people on the train. She goes with him as they stake out the supposed vampire nest. She's uncomfortable in the car with him. They enter the vampire nest and the vampires just run away. Buffy realizes they aren't the killers she is looking for. As she leaves, Spike opens the door for her - shocking her. She asks if he thinks this is a date. He tries to tell her he loves her, but she cuts him off. She rejects him and leaves.
Spike returns to his crypt where he finds Dru waiting for him. She tells him about Darla and Angel and says she wants him back. He says he doesn't want to go to LA and she reveals she knows about the chip. She tries to convince him that the chip can't control him and he can still be evil. Harmony enters and thinks Spike has picked up some vampire and is hoping for a threesome. He tells her it is really Dru and throws her out. He says he's back.
At home, Buffy is telling Willow and Joyce about Spike. Willow says Buffy has to go to Spike and make it clear there is no chance of anything happening. Buffy asks Willow to do something for her while she's gone. At the Bronze, Dru kills a couple and Spike feeds from the woman.
Buffy goes to the crypt and finds the Buffy mannequin and a collage of drawings and photos of her. Spike and Dru arrive. Dru knocks her out with a stun gun and then Spike turns it on Dru. When Buffy awakes she is chained as is Dru. Spike tells Buffy he loves her. Dru says she knew. Buffy says you can't love without a soul, but Dru says they can. Spike says he's going to kill Dru for Buffy. He talks about all Dru means to him, but Buffy isn't impressed. He says if Buffy doesn't admit to something between them, he'll release Dru instead and let her kill Buffy. She still won't say anything. He goes crazy, talking about how women are ruining his life. He admits the whole thing with Buffy is crazy, but he's stuck with it. He starts talking about killing them both, but he's struck by an arrow in the back - it's Harmony. Spike starts fighting with Harmony while Dru and Buffy struggle to free themselves. Dru wins and attacks Buffy. She's starting to succeed but Spike finally frees himself from Harmony and pushes Dru aside and frees Buffy. Dru and Harmony leave. Buffy punches Spike in the face and knocks him down. He runs after her. She tells him she wants him to leave town and never come near her, her friends, or family. He tries to enter her house, but Willow has cast a spell uninviting him.
