Sulu reached forward as Ianto gasped for breath, putting a hand on his shoulder. He could feel his own shoulders tensing as worry and a healthy dose of fear filled him, Ianto's expression and panic doing nothing to help him out. When Ianto moved and grabbed his arm, he switched hands easily, grabbing the towel tight in his other hand and letting Ianto pull him.

Because, the fact of the matter was that if Ianto was freaking out - Ianto, the one who dealt with things that were far more paranormal than the things Starfleet dealt with, who had damned ghost machines for crying out loud, was panicking, and that made Sulu even less eager to stay in the room than he had been before.

"Okay," he said quickly, "All right." He didn't want to ask what had happened - he didn't want to know. He knew he should probably grab some clothes, but... fuck it.
