CHIN's

Claire does some online snooping that causes drama with the rest of the family.

Cameron is in charge of the school’s big spring dance, but when a popular teacher returns from sabbatical, a bit of not-so-friendly competition blooms. And with Claire on chaperone duty at the dance, Phil gets Haley to accompany him to his annual realtor’s banquet and is looking forward to impressing his little girl. Elsewhere, Mitch starts a new job and can’t seem to get a good read on the new boss or the work environment. Jay and Gloria babysit Lily and an accident with Gloria’s purse ignites a case of whodunit and it’s Lily’s word against baby Joe’s.

Things get awkward when Phil shows up at Claire's college reunion. Jay is fixated on winning a big bowling tournament. A wig malfunction during an elaborate photo shoot with Joe leads to unfortunate results.

It's a day of disturbing realizations when Mitchell manages to ruin one of Jay's proudest golf moments, Phil overhears something that may forever change how he sees his little girl, and Gloria stumbles upon Claire's dangerous little secret.

Phil and Claire have a huge fight and Phil hasn't a clue as to what it was over, so Gloria steps in to counsel Phil while Jay counsels Claire. Meanwhile, Jay has some regret in buying Gloria a karaoke machine, and Cameron is in full prep mode for a huge fund-raising event and asks Mitchell and Luke for help.

When Phil and Luke embark on a discovery expedition underneath the house, Phil tries not to let his fear of the dark and of creepy crawlies get the best of him. Meanwhile, Claire takes a nervous Haley to the DMV for her driver's test, Manny's sudden illness before a friend's amusement park birthday party makes Gloria suspicious, and Cameron and Mitchell invite Lily's pediatrician over for what turns out to be an anxiety-ridden brunch.
