Molly goes to the final fitting of her dress and is upset to learn the dress doesn't fit. She starts spinning out of control, trying to lose the last 6 pounds, making everyone a little crazy. She drags Mike to the gym to take a spinning class and they run into an old friend from OA. The old friend has lost over 50 lbs and Molly is so discouraged she runs out. While waiting for Mike in the parking lot, another woman makes a snarky remark and Molly kicks off her side mirror. Molly gets arrested and Mike bails her out and tells her she's perfect the way she is and though she appreciates that he feels that way, she's still determined to fit into the dress.
