Despite his obvious discomfort, Ianto smiled at Sulu's concern. "Yeah, don't worry. I'll be fine once I get used to it. I think that this means it's working, though. I mean. Working to warm me up. Like I'm thawing out or something ridiculous like that." That's what it felt like, at any rate. Like he was an ice cube thrown into a glass of water that'd been out in the sun, and his whole body was struggling to become the same temperature as the water, to dissolve like the ice cube would.

He sunk lower, trying to get more of his body under so that he could get used to the water faster, leaning back toward Sulu but not exactly relaxing against him yet, and letting out a shaky breath as he did so. "I guess this'll teach me to sit outside in November," he said, lightly, although it really was the truth. He hadn't really bothered to think of the consequences of sitting out there, he'd been more concerned with his mental well-being than his physical.
