“The media flatter themselves. They go into a war zone. Sometimes they get shot. It’s nothing personal. Except to the media.”

LOL, sounds like the case here.

None of it makes sense. Random guy gives them ride to refugee area. They get ambushed in vehicle, and friends leaves him behind. Usually, the best way to evade a ambush, is to keep driving away. Don't stop. Unsure, why Brent would be left behind out of the vehicle. If vehicle can move, continue away to safe area to evaluate injured.
