Ianto understood that Sulu was yelling at him because he was afraid for him, but it still hurt that he'd snapped at him like that. Enough so that Ianto, frustrated with himself, sicker by the minute, and equally as afraid for their situation, snapped back. "I didn't want to find Jack sooner! I thought I could handle it--I hadn't tested the boundaries of this virus the last time it happened, I didn't know that it would start to get this bad. I knew that we'd have to start moving if I told you about this, that's why I kept it to myself! Because I wanted to spend more time with you!"

Ianto swayed again, this time more violently, as his emotions were getting to him as well as the sickness. Maybe all of that yelling wasn't such a good idea after all, he thought, ill enough not to realize that Sulu's hand, cool against his almost feverish skin, felt pretty wonderful. Feeling himself tip forward towards the stairs a little more with every rocking of the boat, he moved to grip Sulu's hand harder, his other hand flailing out to find the railing on the other side, grateful that they were standing close enough to it for him to grab onto something solid that wouldn't come tumbling down the stairs with him if he needed to put his full weight into hanging on.

He took a deep breath, letting it out shakily because damn it, yes, he wasn't doing much better than Sulu in the panicking department, and all of this swaying and vertigo made him want to throw up right then and there, Sulu calling him out on what he already was angry at himself for wasn't helping anything. "Look, I'm sorry, alright! I really am. I... I didn't mean for it to get this bad. But any more yelling at me should really be done after we tackle these stairs, because I don't know how much longer I can stand at the top of them without falling and taking you with me."
