While treating a patient, J.D. realizes that he knows very little about Carla, her personal life and her feelings and asks her about it, but Carla tells him she doesn't usually open up to people because the would think she is crazy. Eventually she opens up to J.D., revealing all her insecurities, including that she thinks Turk and Bonnie Chang (Turk's rival surgeon) have something going on together when she watches them taunt each other. J.D. thinks that it is ridiculous and tells Turk about it, who accidentally lets slip to Carla that J.D. betrayed her and told him. Carla gets furious at J.D. and refuses to ever trust him again, as well as telling a hot nurse about J.D.'s secret (that he swaps her shifts to suit him).

Turk brags to Bonnie

Meanwhile, Bonnie is being picked for better and more surgeries that Turk and is taunting Turk about it. But then Dr. Kelso picks Turk over Bonnie to come on the "Doctors Without Borders" program with him and Turk gets his own back on Bonnie by taunting her. But his tauntings are cut short when Dr. Wen reveals that he was only picked over Bonnie (even though Dr. Wen recommended her) because she is a girl and Dr. Kelso is a sexist. When Dr. Kelso admits this, Turk allows Bonnie to go on the program instead but she refuses and makes fun of Turk further so he decides to let Todd go on the trip instead because he knows he would spend the whole trip thinking about Bonnie being better than him.

Elsewhere, Elliot tries to get noticed by and get more of a relationship with Dr. Cox and repetitively tries to have a conversation with him and he eventually allows her to help him: by giving all the patients the bad news on behalf of him, but Elliot soon finds the sadness to overwhelming for her and forgets about Dr. Cox and his new found respect for her, and puts her happiness first.
