Sulu couldn't help but let out a small, strained laugh at that, shaking his head in his hands. Ianto hadn't wanted to upset him? Sulu could understand that. Of course he could. But if he'd just been honest, they could have looked for help. They could have done something before this, before Ianto could hardly even stand.

"You should've told me," he said quietly, though a little fiercely, "Damn it, Ianto, you should've told me before. Because now I really am upset. I've been acting like an idiot this past month, thinking things were getting better when they weren't." He sighed and pulled at his hair, head tilting side-to-side slowly. "Now. God, Ianto," he said, finally looking up, realizing that the anger he'd felt just moments before was dissipating into fear. "I might not be able to do anything now. It might be too late and I don't want to lose you again."
