You're a doctor...You were recently hired to take care of the fighters once they leave the ring regardless of whether or not they win or lose...When he first saw you he got distracted and nearly got his jaw broken...

You checked out his jaw later that night as well as examined the scars all over his body...He goes to you now for the smallest of things just because he wants your attention...He lets you check out his cybernetic arm and has the impulsive thought to just squeeze you with it...
