Ianto rubbed his hand on Sulu's back gently as he spoke. "Yeah, I... I'm sorry about that. I know that you're not a fan of heights or falling from them. I'm not the biggest fan of cliffs or falling from them either. But we made it, yeah?" He didn't notice the fact that Sulu had trailed off for any particular reason. If the other had mentioned the fact that there was something up, he would have noticed it too. Well, he did, sort of, unconsciously. The air was definitely thick, and almost musky, and he really didn't want to take his hand off of the other man, for some reason. He didn't question it, though, instead letting it slide to rest on Sulu's shoulder as the other turned to look at him.

"Mmm?" Ianto questioned, unconsciously sliding closer to Sulu, running his hand lightly down the skin of Sulu's arm, wondering at how fit and toned the other man was, and at how nice he smelled, despite the fact that they'd just run for their lives and swam through the ocean, and that logically, he should only smell like salt water at this point.
