Luke wants to tag along with them to try to get back together with Marissa, but she later changes her mind about him when she catches Luke making the moves on Holly Fischer. Back in Newport, Jimmy has plans of his own to get out of his financial and legal problems, which don't sit well with Marissa or Julie. Sandy gets a new job at a large prestigious law firm, which Kirsten can't understand why.
