I guess he was dying, Morgan couldn't do anything so he left.
Yeah he's clearly seen breathing in a later shot too. So either it's intentional, or the guys a bad actor and they didn't want to reset the shot lol
It was too obvious for post-production to miss, and if it was a mistake, they could have simply shown the shot where Morgan's eyes open and nothing else. Think the dude was just dying.
What do you think?
