Joe had had decades of practice at not letting brief flashes of recognition cross his face when they hit, especially when it was something he shouldn't rightly have recognized without being told what it was.

He could only hope that practice was still in effect, because those marks -while not exactly the same- were incredibly similar to ones he'd borne himself not long before, ones that were still etched on the bones of his forearms because bones didn't heal the same way skin did.

As it was he just lifted both brows slightly at the explanation, "And do you often admit murder to people you've just met?" It was utter curiosity, and 'admit' instead of 'confess' was a very deliberate choice of phrasing, partly because confession implied a level of guilt that was currently lacking, but mostly because the question in and of itself wasn't an accusation to be confessed to.
