Ianto can tell that John is uncomfortable. He can read it in his body language and the way that he keeps hedging on answering his questions. Even now, when he's being as direct as he can without stepping up and physically pinning him down to get his replies. But he doesn't understand. How can he, when on one hand John will openly flirt with him and on the other, he'll go out of his way to avoid pretty much anything to do with Ianto being accepting of that fact. To wanting more.

Ianto sighs, knowing that they're both tired and that it's only a matter of time before this AI decides to provide any 'helpful' input into their conversation. But enough is enough, John. He's probably already let it go for too long. Enough.

"The thing is," Ianto continues, "you could have told me off a long time ago if you weren't. It's not like I've kept this a secret from you. I'd like to imagine the kiss was a pretty big tip."
