When Dede drops in unexpectedly, Mitchell and Cam come to a realization about her effect on their lives; Phil, Luke, Alex and Haley all have different bad news to break to Claire and compete about when to do it, the tiny window of time after her monthly spa day when she's her most relaxed.

Mitchell sneaks out to "Hero-Con" with fanboy Phil, dressed as their favorite characters from the show "Clash of Swords." It's great until Phil commits the ultimate fan faux pas. In a clash of another kind, Gloria's dinosaur party for Joe is ruined when her nemesis, Dr. Donna Duncan, upstages her with a far bigger and better party right next door.
