Lover's Leap - S1.E6

After their illicit kiss, Laurel tells Mark she can't be with him when he's still with Jen. Mark tells Laurel he will break up with Jen. While feeling she may be losing Mark, Jen contemplates having sex with him in order to keep him. Scott throws an Equinox party. Craig leads a one-man protest at the Cafe Java but when he chains himself to the table and insults Maggie, she leaves him there overnight. When Anika hears the ""torrid affair"" rumours going around about her, Erin tells her it was Laurel who started them (when really it was a jealous Erin). Laurel and Jen work uncomfortably on a school project together. Mark goes over to Jen's to end things with her but they end up having sex. When Mark falls asleep, Jen is left looking very unsure of herself.
