"Nothing that you're not already doing," Ianto said, softly. The fact that Sulu was there with him, that he'd helped calm him down, helped him talk about it, and was now going to curl up behind him, his arms around him and...yes, alright, even holding his hand, all of that would work together to hopefully reassure Ianto's subconscious mind that, even while he was sleeping, nothing bad would happen, and would keep the nightmares at bay.

"If I get another one tonight," Ianto said, "it'd have nothing to do with anything that you're not doing, and more to do with just... I don't know, an imbalance of chemicals, or something? Whatever the scientific explanation of a nightmare would be. That's McCoy's area, not mine. But no." He laced his fingers in Sulu's, relaxing against the other man and finding it not very hard at all to start to feel himself drifting off.

"I... I'll be fine. I mean, even if I have another one, it's only a nightmare, yeah? So long as you're here with me to deal with that, then it doesn't matter in the end. That having been said..." He brushed his fingers across the back of Sulu's. "You get some sleep too, alright? I'll probably sleep better if I'm feeding off of your good energy, after all." As hokey as it sounded, it was true. He'd sleep a lot better knowing that Sulu was too.
