"Yeah, well," Jack said, and he would shrug if he could at that moment, "he's going to know that something's up when he wakes up wherever we end up taking him, or well, whenever he wakes up and realizes that he's not stuck in the tunnel with you like he remembers being before."

Jack thought for a moment about Sulu's comment, about Ianto mentioning something sooner than he had, before sighing. "Look, I... I can't really say what goes through his mind sometimes, but. Knowing Ianto, he probably figured he could handle it on his own. He gets like that, sometimes. Like he can't remember that there are other people around that are perfectly willing to help, if he'd just say the word. Or, y'know. Even allude to something being the matter, really. It's really easy to miss things with him, too. He's good at hiding."
