Ianto clung to Sulu, clung to his reassurances and his voice and the fact that, yes, it really had been just a bad dream. A very realistic dream, based on memories he had hoped he could bury and never have to deal with ever again, but a bad dream nonetheless. He hung onto those reassurances, repeating them to himself in his head, which was why he almost missed Sulu's comment about the bathroom, there. But it stuck out, enough for Ianto to be more than a little confused by it. And the fact that Sulu's voice seemed to be muffled, by...his hand?

Ianto slowly peeled himself back from where he'd been clinging to the other man, pulling back to be able to look at him, realizing that he had his hand over his nose for a reason, that that wasn't a normal pose for someone to do unless... "Oh god," he said, reaching a shaky hand up to rest on the side of Sulu's face, "did I...? Was that me?" Of course it was him, though. How else could it have happened?
