Still chortling to himself, Ianto leaned in again and kissed the lip curl, trying to smooth it out and to diffuse Jack's grumpiness. "I'm sorry, I'm sorry. Yes, Jack, a lair in my basement's the equivalent to 'I love you' out of you. It says that you want to stay where I am. You came to Canada because I was here."
Definitely not the romantic thing that this could have been. Ianto didn't seem to mind, save for Jack's grumbling. He smoothed another kiss over Jack's chin. "I love you, too."
