[Glasses? Goggles? Fiddleford shakes his head, trying to focus on what he's doing rather than asking questions for what is probably something ridiculous.]

There are fragments of bone in his arm here from where the fracture occurred, splintered into different pieces in various spots. It's part of what's causing the pain that Stanford is in right now, and if allowed to remain, they may even cause an infection.

[Thus, he's trying to see if there's any pieces close enough to the surface of the skin and stump of arm on display that can be removed without making it worse.

There's a pause, debating whether or not if he should even bother warning Bill that "this might hurt" while he's removing what he can, but after a moment...]

Don't move.

[And that's about the amount of warning Bill is going to get before he starts working here. It's going to feel like something sharp is poking into the mess of skin and fractured bone here as he tries to keep his hands from shaking, trying to keep them under control as he deals with the pieces of bone broken off in here. It's probably a good thing that Stanford isn't the one in control here because yes, this would be a very uncomfortable and painful thing to be awake for, really.]
