[There are several beats of silence where Accelerator seriously considers simply not answering that question. But... as much as he'd like to say the answer is a personal one, it isn't. Not really. A lot of people back home know about the choker and limited use of his ability. It may not be common knowledge, but all the powerful people know, so keeping it to himself is kind of pointless.

Drawing in a slow breath, he reaches up to tap the small black device around his neck.]

This thing. It fills in for some missing brain function and lets me use my ability, but it's limited and can be screwed with if you know what you're doing.

[He looks a bit pissed as he continues his explanation.]

For a while the higher ups could limit its function remotely or shut it off entirely, so if I did something they didn't like they could shut me down. It was a huge pain in the ass.
