They weren't words of comfort, but at least Gabriel wasn't alone in this. He certainly didn't have it in him to refute that this was what they were supposed to be. So he just leans forward, until his head is against the bars. It's the closest he can get to comfortable with his body like this.

Rhys might hear Gabriel sniffling from time to time. Or he might not- there were plenty of other noises of fear and sadness coming from all the other cells, after all.
