Ianto ran his thumb over the back of Sulu's hand clutched in his own, recognizing that Sulu really did mean what he said. And the strange thing was that Ianto trusted him in his words as well. They weren't just words, after all. Sulu had told him that he would do anything for him, and then he had, bringing him back from the dead, so. He couldn't get much more proof than that.

At the use of his full name, though, Ianto paused, biting his lip as he remembered a conversation that he'd had with Merlin what must have been only earlier that day, even though it seemed like it was ages ago. He lowered his head, tucking his chin to his chest as he contemplated exactly how to breach the subject, but then the words were tumbling out of his mouth before he could really formulate them into anything smoother. "...do you mind that I don't call you Hikaru?" he blurted, wincing at how out of the blue the question seemed to be, but there was no taking it back now that it was out in the open.
