When Clem and Nick run into Nick's ex-girlfriend at their hotel during a romantic weekend, Clem is upset to learn that Nick and his ex once lived together – in the same apartment they live in now. Also, Shannon's friend tries to persuade her to throw a big party while Clem and Nick are away.

Clem feels her former "fun" life slipping away after attending Shannon's school's Open House and joining the PTA, and decides to liven up the low-key bachelorette party she originally asked for.
