He watches Ianto's fingers, grinning slightly because he knows exactly where they're going beneath the covers. He's quite curious to see, too, even though he knows what he's going to see. It's odd to see completely unblemished skin where he's got used to seeing marks, and he runs his fingers over it too, just once, as if to confirm what he's seeing by touch, as well.
"Exactly. Confirmation, at last. Well, except that this could just be another simulation, of course - we've no way of knowing!"
