Ianto takes in a long breath, letting it out slowly as he tries to force himself to relax. John is right, of course. He shouldn't expect so much of himself. He's used to working in a team scenario himself, and he never handled it all on his own there. Tosh did computers, Owen did medical, Gwen handled the people, and Ianto handled the research. The logic. Helping to piece their findings together and give them more to work with, so that Jack might direct them where to go from there. Or at least try to.

He watches the other man for a long moment, before loosening his arms across his chest. He really isn't angry with John. Like he's said, he had set out to get him here alive. And he'd done exactly that. He'd gone above and beyond in doing that, as far as Ianto was concerned. In fact...

"And part of that task was insuring that I didn't sunburn?" he asks, but the words are mild now. Because as irritable as he is, he knows he's not being fair, and he hasn't missed the small self-deprecating bit of what John's said, reminding him of why he had insisted on joining him. Even if he really isn't very well-equipped for, well, any of this.
