Ianto shrugged, waving it off. He really wasn't upset about Sulu raising his voice to him at all. He'd been frightened, Ianto really hadn't been able to help when the other man clear needed it, so. Of course he'd lashed out, it was only natural. "Don't worry about it," Ianto said gently. "I know you didn't mean to. It's alright, really. I just... I wish..." Well, even if the ghost had recognized that Sulu wasn't mad at Ianto, he'd still be mad at the ghost itself, so he wasn't sure that knowing Sulu hadn't mean him any harm would have done much good at all. After all, he'd've still been lashing out at something personal to the ghost, whatever that meant.

At Sulu's next words, though, Ianto froze. Crap. "Oh," he said, helpfully. "God. I, uh... Here," he said, stepping forward to help the other man up from where he was seated on the toilet, quickly flipping the lid up. He wasn't sure how much help Sulu needed otherwise, or how much help he was willing to accept, but he stayed very close by, should Sulu even look like he was asking for anything. He didn't know what to do about the head wound; the bleeding wouldn't have stopped yet, even if it might've been slowing. He just knew that Sulu'd probably appreciate it if he removed his hands from his face area, if he really was going to throw up, so he carefully removed his hand and the towel from the side of Sulu's head.

"Do... Do you need me to...?" he asked, leaving the question open ended, because he really didn't know what Sulu might need him to do, he just wanted to be able to do whatever he could. Sulu'd had to put up with him being ill because of that virus, and when they'd been kids that other time, so. He wanted to return the favor, but even more so, he wanted to feel useful, even in the slightest bit, and not as helpless as he had out in the parlor a minute ago.
