He follows her gaze and blinks at the doorless wall that they just came through. Suddenly his conviction that they're not in Hell is shaken. Was this another trick? Another illusion? Was Carrie even real?

Maybe she was just meant to keep him busy. But he could feel her apprehension, her blood. If this was just an illusion given by drones than he wouldn't be able to trust his other senses.

He looks at her and then around them at the dark hallway. He can't see any other doors in immediate sight. Which forces them either up the stairs or down the hallway. He leads her down the hallway. They'll have to run into another door eventually. Plus, he's not sure how much exertion Carrie can take. "This way."
