It’s the first day of school for the families. With all of the kids out of the house, Phil misreads how Claire is dealing with the empty house. Jay and Gloria have a disagreement over Manny’s choice of an outfit for his first day of school. Also, Mitchell and Cameron become very upset when they find out that Lily suffered her first bump to the head.

Dede, Claire and Mitchell’s mother, stops in for a surprise visit and wants to try to make up with everyone that she offended during “the incident” that she caused at Jay and Gloria’s wedding. No one is eager to see her, but everything comes into play when the whole family meets at Claire’s house for dinner.
