Even though Sulu really wouldn't mind just keeping along with the way things had been going, he felt the shift in emotions too and... Well. His own train of thought went a little like Ianto's; the mood was a lot different from the one they'd been in just moments before he'd opened his big mouth, and maybe they shouldn't be just going with the flow.

And he knew what Ianto was hinting at, twisting his wrist to hold Ianto's hand in his own, but that didn't mean he wasn't going to play maybe a little dumb. He knew Ianto'd get flustered (or annoyed, but the kind of annoyed that was sweet and good, instead of the kind that got him socked in the shoulder), and that was something he wasn't able to pass up. "Or...?" he echoed back, grinning a bit against Ianto's neck.
