Ordinarily, he would have heard Rose coming, either by the creaky floorboards or by some other means, but this time he was caught by surprise. Ianto's head came up, mouth open a little. "Oh, Rose, there you are. Sorry, didn't hear you come in. Sit. Please."
With someone else there, Ianto could force himself to step away from his fussing and actually take a seat himself, feigning comfort and relaxation, if not actually indulging in the real thing. "Sorry, I'm a bit out of sorts at the moment. Um. Care for a cup? It's very good." It wasn't quite boasting; Ianto's tea was brewed to perfection. It was a coping mechanism, of sorts.
