"I really really don't understand what York has to do with anything between us. I'm not interested in him and he's got a girlfriend he's over the moon for." Ianto leaned in, as if imparting a great secret. Maybe it was a secret, least as far as Jack was concerned. "He was winding you up. Besides, before he had his hands all over me, you were mentally shagging him up against a wall." Forget mentally undressing. Jack went beyond that, Ianto knew.
That's just the way it went, and he knew this and was willing to accept it, even if he didn't like it much. "There .. will be trust. It's built, not just made. And York is my friend, but you ... you are my Jack." Which was infinitely better, in Ianto's meager opinion of things.
