Frankie insists that Brick ask Cindy to the prom, but her suggested "promposal" doesn't work. Brick's original idea to ask Cindy does work, and she accepts. Worried that Brick and Cindy will have no one to hang with at prom, Frankie organizes a pre-p... (more)rom party with Brick's old friends from the socially-challenged group, including Arlo and Zack. This backfires when it becomes apparent that those kids have outgrown their quirks while Brick still hasn't. Brick and Cindy enjoy a private prom at the Orson Public Library, while Mike tells Frankie he is happy to have a child who doesn't think like everyone else. Elsewhere, Lexie scolds Axl for not getting Sue a 21st birthday gift. He gets Sue excited by telling her he is planning something special, but when the day comes, Axl is completely stumped. Sue is angry, but Frankie later tells her about how Axl doted on her when they were toddlers, lifting Sue's spirits again.
