Ianto sighed, both at the question, but also in relief because Sulu's rubbing his shoulder was helping him warm up. He could only hope to hide the first reason behind the second one, and hope that Sulu wouldn't notice. "Mmm," he said, in response to Sulu's actions, letting out a soft noise of approval as he did start to warmer than he had before.

How to answer Sulu's question without outright lying to him, though? Ianto had promised himself that he wouldn't outright lie to the other man, and he intended to keep that promise. It...didn't cover implying something other than the truth, he decided, but. Outright lying was out, and that would be difficult, especially in this situation. "I... I've been alright. Cold. Still tired, but. I mean, I guess that's to be expected. I... I think things're getting better, I just. I guess today's just a bit of a relapse, it seems," he said, trying to cover for the fact that he couldn't pretend to be better like he'd been doing for the last week, when Sulu and Jack had been visiting.
