Stevens is unwillingly sent back into the Source Code repeatedly in frustrating, exhausting attempts to learn the bomber's identity. He tries to warn authorities on the train and flee with Christina, escaping the explosion. Other times he cannot locate or disarm the bomb and dies on the train. But Rutledge insists the alternate timeline is not real. It is revealed that he has been "with them" for two months since being reported killed in action in Afghanistan. He is comatose and missing most of his body, hooked up to neural sensors. The cockpit capsule is in his imagination, his brain's way of making sense of a missing environment. A confused and frustrated Stevens asks, "As one soldier to another, am I dead?" Angry to learn that he is on life support, he asks to be disconnected after the mission. Rutledge agrees.
