Ianto found it very unlikely that he'd never disappoint the other man. Sulu was very kind and very understanding, but Ianto couldn't believe that he'd be understanding of everything. He knew sometimes that his reasoning could get a little ridiculous. Especially when it was something concerning himself; he'd grown up with only himself to keep an eye out for himself, and he still wasn't used to the fact that well. That he had people like Sulu and Jack who cared for him a lot, and really wouldn't mind if he asked them to do things for him.

At Sulu's question, Ianto raised a hand and put it on the side of Sulu's face, cupping the corner of his jaw and running his thumb over the other man's cheek. He knew that his hand was freezing on Sulu's skin, and that it had to be a little uncomfortable for the other man, but. He was moving, he was touching him. He was still alive, and well. If Sulu was admitting that he, the king of optimism, couldn't hold it together on his own without Ianto's help, then Ianto was going to try and help. Sulu had done so much for him already, it the least he could do for Sulu, to try and keep a fresh mind about things. "I can try," he said, softly. "You know me. It... It won't be easy. But... For you, for Jack, for all of us... I can certainly try."
