i'm copying/pasting a bit for you too, SORRY. he's a former fighter pilot/boy genius who wasn't accepted by any crew after a traumatic brain injury, but he's still the best pilot in the galaxy (according to himself, he's still got a bit of an ego on him for having so many repeat rejections). tl;dr, his natural brain and his cybernetic brain don't always get along so he literally shuts down and freezes whenever he's overstimulated. sometimes if you ask him a complicated math or science question he'll just turn into a statue and then two hours later, after it's too late, he'll finally work it out and have an answer. think of him as a walking blue screen of death. despite all of that, he's pretty happy-go-lucky and just glad to be alive, and i imagine that he'd be like a loyal dog to the entire crew just because they took him on when no one else would.
