There's been a lot of people who've come and gone. I can't claim to say I've known them all, but I might've met a few. Try me? :)
And.. that sounds horrible. We deal with injuries from time to time here, but mind control is probably the single worst thing you can ever do to a sentient creature. If anyone shows up with cybernetics, though, I'm confident I can help them. It's one of my specialties.
