Unable to shake his grief, Carter decided to join Dr. Kovač in Congo without Abby's support. While there, he mended his previous rift with Kovač (due to their feelings for Abby) and they began to understand one another better. When the clinic is overrun by militia, Carter is threatened by guerrilla soldiers. However, a young soldier recognized Carter as the doctor that tried desperately to save his brother though he ultimately failed. Out of respect for Carter's actions, the guerrillas spare everyone at the clinic aside from an Army soldier they had been treating.
