At the steakhouse, everything's coming up Tom. He's got a dame with great bazungas and a "jazzercise ass" into him, and Harlan declares it Tom's night. He urges Tom to keep the party going.
Donna intends to keep the party going at the lock-in, and her first move is to break down the new object of her desire so she can re-build him. No matter how she rebuilds Walt, though, all those parts are gay and into Jake Ryan in Sixteen Candles. She prepares to tell Walt about Maggie cheating on him.
Sebastian and Mouse pull up outside the club and manage to find parking right outside, where there is no longer a line, nor anyone watching the door and checking IDs. Carrie is lifted up onto a pedestal to keep dancing and enjoying her freedom. From the pedestal, she sees Tom dancing nerdily up on Jazzercise Ass. This sight is distressing for many reasons, and so distressing that she freezes. The cameras catch her, and she is backlit by dozens of distraught-looking Carries. Tom looks up, and in that moment they are both busted.
Carrie is in much more trouble than Tom, though. Tom tries to get Carrie out of the club, Larissa intervenes with, "You didn't tell me you were bringing your hot dad." She may be one-dimensional but she's a fun dimension. Tom says he's allowed to treat her like a child because she's only 16. Larissa is so stunned to hear this, and just high enough on coke that she blurts out the information about Carrie's internship, which she didn't know was a secret. She doesn't even care that Carrie is 16. Larissa and Harlan flirt, and the only one still angry is Tom.
Things are also going pretty inconsequentially at the lock-in. Maggie finds Walt, who is upset. Maggie admits it's true, and that it's all her fault. Walt breaks up with Maggie once and for all, and Maggie is crushed to learn that just talking about it won't help.
Sebastian and Mouse fail to find Carrie at Limelight, since Tom has pulled her away. Maggie gets a nerd to unlock the doors and let her out of the high school, which she now hates and says has nothing for her. Sebastian and Mouse give up, and his car is being towed since there are no legal, available parking spots outside clubs.
Donna and Walt have a connection, sitting against the lockers, discussing their heartbreak. Is this when Walt will realize Donna is the perfect Hag? No, it is when Walt will make out with Donna.
Tom yells at Carrie at his car, and it's a pretty good/realistic scene until Tom goes off on a speech about "what happened to the girl who..." In the end, Tom is pulling Carrie from New York and her internship, to prove that some actions have consequences. I don't know, Tom, Carrie has a pretty sweet deal going at Interview. I hope his date is OK...
