Ianto doesn't understand why John is pushing the topic when he quite obviously does not want to talk about it either. He shoots him a glance in return, the expression on his face making it pretty clear that he doesn't believe him for a second, before he makes to start unbuttoning his over-shirt and readying himself for bed.

"You don't have to lie to me because you think it might make me feel better, John," he replies, and it's hard to keep the frustration out of his voice when he does. "The only reason that you're here is because I couldn't even fend for myself for a whole week without needing to call you to rescue me, and the only reason you're staying is because you damned near lost your arm in doing so. I'm not kidding myself. Neither should you."
