Ianto doesn't understand enough of what's going on to know what the tone of the other man's voice should mean, but he. Appreciates the fact that he isn't interrogating him anymore, and he hopes that isn't just because it looks as though he's about to pass out. The fact that John isn't fighting him or protesting his touch means that he does have the leeway to allow himself more, though.

Tentatively, he shifts closer to the other man, rubbing his hand against his leg reassuringly. Doing his best to still be on his guard in case he has to leap back out of harm's way for any reason, but wanting to be close. Maybe it will help...?

"John?" he tries again, after a long pause, looking for some sign of -- anything, though recognition would be the biggest relief at this point.
