After a month of dating, J.D. is a bit frustrated that Kylie still doesn't want him to spend the night. That frustration leads to temptation when kooky psychiatrist Dr. Molly Clock returns to Sacred Heart to check on a patient. While J.D. struggles with whether or not to act on his residual feelings for Molly, Carla tries to hold back her true feelings when she learns that Turk is still talking to his ex-girlfriend. Meanwhile, Dr. Cox and the Janitor enter into a friendly wager over whether or not the Janitor can get Elliot to go out with him.
