The little smirk grew wider and Ianto turned his head to grin into Jack's face. "You mean you thought I didn't know? Jack, honestly, you tell me a million ways every day without saying a word. I'd have to be a complete idiot or Owen to not know. You're building yourself a lair in my basement, after all. That says a lot."
