When Mel and Joe discover Lennox is secretly dating her teaching assistant Emerson, Joe talks Mel into putting her foot down and forbidding the relationship. But things don't go as planned, and Lennox ends up moving out… and into Emerson's apartment. Meanwhile, Ryder is stuck at the Canadian border after leaving his passport somewhere in the house.

Mel is completely on Joe's side when he's involved in a hit and run, until she discovers the other driver is her beloved hairdresser Calista. Meanwhile, Ryder tries to win Stella back with a grand romantic gesture during class — much to the frustration of her teacher.
