Sulu didn't know what he wanted to do right then. He knew from how Ianto had responded that, while he'd never passed out before, he'd been close to it before, and that made him ache. To think that he hadn't even noticed it... and that Ianto had hidden it from him. He wondered if Ianto had been doing that to keep Sulu from feeling terrible, and realized that it really, really hadn't worked.

"But you've felt like it," he said quietly. "Ianto - have you even been feeling better at all?" His hands moved to Ianto's shoulders, because he didn't want to be petting his hair any more. He was trying to keep from moving away, and this was the only way to do it. "You have to tell me, right now. How long have you been feeling like this?"
