Ianto wonders how much John will allow of him, out here in public as they are. It's one thing to have put on the display they did in the ship, for the sake of the display itself, and to have set the other man off with that. Here and now, walking side by side down the street, however. This is no display, this is simply them, John and Ianto. And how he'd like to touch him in return, no matter who there is that might see them...

Tentatively, he slips am arm around John's waist, casual and supportive, for all that anyone else would care. Though he rubs his fingers against the other man's lower back in perhaps a bit a bit more intimate a manner than a friend might do otherwise.

"I don't," he replies, honestly. He turns his head to glance aside at the other man out of the corner of his eye before he continues, lightly, "Though if such is the case then I can only hope that we might be able to come to some arrangement of paying it back."
