His brother Dan decides to stay with JD for a while after their mum's new fiancé kicked him out, but after spending some quality time with him, Dan isn't sure if he likes the cynical person his little brother has become.

In a `Wizard of Oz' homage, JD is trying to go home, Turk searches for a heart donor and Carla worries that she doesn't have the courage to become a parent.

JD becomes annoyed that his new girlfriend Julie doesn't laugh, but rather tells him when things are funny. Afraid that he is going to screw up yet another relationship, Elliot encourages JD to start saying his feelings out loud.
