Matt is edgy, telling only his sibling he found an out of state summer job so he'll leave home in days, not months. Simon finds a brilliant trick to train happy for a TV pet food commercial, but there's a stage-fright complication. Mary rudely scolds Matt, unlike Wilson who leaves diplomatically, for getting physical at home, but her doctor notifies she's pregnant. Lucy cruelly keeps suitors Jimmy and Rod, who both chose Eric as career day model, dangling, but Wilson, who appreciates her help with Billie, arranges a date with Kenny, whom she may really want.

Matt worries now he's about to leave home, as self-absorbed, phone-glued Mary hasn't even got a clue what's happening with their younger siblings, nor is any use for either. Simon is heart-broken when Happy's original family head Jack Martin turns up and returns with a lawyer to claim the dog back. Eric considers his parents's surprise visit awkward and pointless as Matt won't be around to hold his valedictorian speech. The colonel however takes charge of an operation dog rescue inspired by Jimmy and Rod. Those two also undo Lucy's idiotic dumping of Kenny for being 'too perfect to be interested in her' and hold a remarkable church sermon. Matt changes his plans after a call from the colonel, learning about it and Annie's confession that Mary's pregnancy diagnosis got mixed up with her real one.
