Ianto shuddered slightly at the force of the emotion behind Sulu's words there. What with the sex and the alcohol, his mind wasn't quite in the right place to be able to adequately answer Sulu, which he regretted deeply because...they didn't really talk about these things all that much. He forced his brain into gear, however, enough to form a coherent thought back. "...you did save me," he said, softly. Maybe not from the 456 directly, but. He knew, Jack had made it abundantly clear, that without Sulu not giving up hope...Ianto would still be dead, and Jack and Sulu would not be the same people they were today.

He slowed the pace of his hand, almost stopping, as he lifted his head to press a kiss to Sulu's forehead, a far cry from the passion that they'd been entangled in moments before, but equally as heartfelt. He couldn't say it, not quite yet. Certainly not as addled as he was in that moment. But that didn't mean he didn't feel it, and he hoped...that Sulu knew it as well. "You did save me," he said again, and it was clear from his voice that he didn't mean just the once.
