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.
Dede drops at Mitch and Cam's place revealing that she and Cam are friend and making a shock revelation to them.
And Phil and the kids try to deliver bad news to Claire because she is in an exceptionally good mood, only to disappoint her. Phil also has a role in Jay and Manny's movie but he is terrible and on the other side, Gloria sounds like the monster they created for the movie.
But Phil is the only one who saves the day by delivering a good speech about mothers.
