S5E7 — My Way Home

In a "Wizard of Oz" homage, J.D. 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. Meanwhile, Elliot doesn't believe, that she has the brains to lead a question and answer session. Also, the Janitor is painting color coded lines throughout the hospital for easier navigation.
