In the episode, "Strange Bed Fellows," Dr. Luka Kovač instructs Pratt to go to Darfur, Africa to join Dr. John Carter in a Doctors Without Borders program after Pratt helped a friend avoid a DUI by sending a vial of his own blood for the blood alcohol test, rather than his friend's; the friend later drove drunk and nearly killed a kid. To avoid legal repercussions and also to force him to think about his actions Dr. Kovač sends him away. When Pratt challenges Kovač and says he won't go, Kovač says he has two choices: leave for Darfur or have the DUI case info released and see his medical career come to an end. Pratt eventually decides to go, giving him the opportunity to move up to the position of attending physician, which Dr. Victor Clemente could not fulfill. Pratt becomes a better doctor for going to Darfur as he gets a sense of what it means to push himself under genuinely impossible and horrifying conditions. He sincerely thanks Luka for making him go, and the two doctors are back on good terms afterwards.
