Sulu made a quiet, calming sound when Ianto trailed off, the hand Ianto was holding on to clutching back at him tightly. Sulu had no idea what Ianto was going through, not really, but even then, his explanation wasn't a surprise to him. Sulu could tell that sometimes Ianto... thought about it, maybe without meaning to. Thought about the dark and whatever was there, waiting for him, waiting to hurt him and it made Sulu angry. What kind of afterlife was that?

He knew that having things making noise all over the flat wasn't going to help. There wasn't going to be something to fix, not so simply. Knowing that, he didn't know what to say.

I want to be able to help you when things get that bad, I just. ...You're still freezing," he said quietly, because Ianto was still cold, and he might've set back any positive developments by sitting out there for so long. He didn't even question that Ianto was getting better - he had to be.
