Jay recently married Gloria. Now Jay is trying hard to keep up with his much younger and hotter Colombian wife, along with her passionate pre-teen son, Manny. Claire is having a hard time raising her own family. Her husband Phil is great, except that he thinks he's "down" with their three kids, much to all their embarrassment. And, Mitchell and his enthusiastic partner Cameron have just made a major life change by adopting a Vietnamese baby named Lily.
Jay has problems trying to bond with Manny, but takes advantage of Manny's father not showing up in an effort to make peace with him, even though Gloria believes there's real peace in the household. Phil goes behind Claire's back and gets a bike for Luke, then really ends up lying about it when the bike gets stolen. Mitchell and Cameron begin daycare classes with Lily.
Claire and Phil have mixed feelings regarding the first day of school for the kids. Jay and Gloria argue about an outfit for Manny, and a minor problem with Lily gets blown out of proportion by Mitchell and Cameron.
The whole family comes out to support Manny's newfound interest - fencing. It turns out he's quite masterful in the sport, but Jay's proud enthusiasm triggers an old childhood wound for Mitchell. Meanwhile Phil is determined to find where Luke's hidden talents lie.
Jay has a sleepover for his grandkids, but Haley is looking for a way out. Claire tries to get a perfect anniversary gift for Phil, and Mitchell and Cameron discover that their ladyfriend is crazy and jealous of their daughter.
Phil and Claire cancel Christmas for their kids until they confess to wrongdoings at the house. Jay is hesitant to celebrate Gloria and Manny's holiday traditions. Mitchell and Cameron take Lily to meet Santa.
