INTERESTING LIFE LESSONS —INDIE ROCK BAND “AMERICAN AUTHORS” PERFORM —Carrie (AnnaSophia Robb) and Walt (Brendan Dooling) are faced with kicking out their new roommate when she makes herself too comfortable. Walt summons the courage to tell Bennet (guest star Jake Robinson) how he feels about him at his eighteenth birthday bash – at a VIP Z100 concert – but things go horribly awry before Bennet can respond. Samantha (Lindsey Gort) and Mouse (Ellen Wong) meet, and Samantha wastes no time giving Mouse sex tips. Back in Castlebury, Sebastian (Austin Butler) and Maggie (Katie Findlay) run into each other; and the evening doesn’t go exactly as planned when Tom (Matt Letscher) invites girlfriend Deb (guest star Nadia Dajani) to spend the weekend with him. Chloe Bridges also stars. Amy Heckerling directed the episode written by Jessica O’Toole and Amy Rardin.
