"It does," John protests. "This is better. Unless you topically numb my whole arm you won't stop me feeling it entirely, and that's really not a good idea with this kind of damage because then I won't be able to feel anything bad happening. It's my arm, Ianto, don't you think there's a chance I want it fixed?"

Without an arm all the things John loves are a lot harder to do, if not impossible. It's not something he'd gamble on lightly.
