Jimmy's waiting for Louise at the next hotel, with the money transfer.
Intrigued by Louise's standoffishness, Jimmy came here in order to figure out what's going on…and maybe sneak in a kiss or two and top it off with a proposal.
Jimmy rents a separate room for Thelma.
Louise passes off the envelope of money to Thelma for safekeeping.
J. D. pops out of nowhere as soon as Louise leaves, and Thelma invites him in all his chiseled glory into her room.
After a passionate encounter, J.D. 'fesses up that he's a pretty darn good thief who politely holds up corner stores for a living. Wielding a hair dryer as a gun, J. D. recites his gentleman outlaw speech, which includes the punny line, "If nobody loses their head, then nobody loses their head."
