Buffy the Vampire Slayer

Buffy notices that Dawn is spending a lot of time around Spike and assumes that Dawn has a crush on him. Dawn surprises her, however, by telling her that Spike is in love with Buffy. Meanwhile, a train pulls into the Sunnydale station with every passenger slaughtered by a ravening vampire, and Buffy is finding it hard to concentrate on the investigation while simultaneously fending off Spike's advances.
