it doesn’t hurt really, not anymore. it’s just in the way. giant bulky cast on his arm throws off the sense of balance he’s worked so hard towards. also it ITCHES. ( that’s actually the worst part.) he’s not supposed to itch inside the cast though, because stitches, because surgery. still bruce isn’t a r o u n d to see it, out on patrol which is probably the only reason tim hasn’t been dragged away from his research on the batcomputer already. ( both alfred & bruce have kicked up their maternal instincts since he broke his arm. especially impressive on alfred’s part actually. )
so he snatches one of the chopsticks from his sushi dinner and slides it inside the cast, even if it does smell a little like his spicy tuna roll. sacrifices must be made because the prickle of his skin is starting to drive him nuts. tim’s tongue is stuck between his teeth as he shifts the dull point, almost right where he needs it.
so of course, that’s about the time bruce clears his throat behind him and tim nearly breaks off the end of the chopstick inside his cast when he jumps.

“ is it truly necessary to give me a heartattack? honestly B, i know i’m not supposed to scratch but i’m literally dying over here ! “ no, tim isn’t being an overly dramatic teeanger, why do you ask?
