[@BCTheEntity] Sooo, out of curiosity... why did you assume the at least two armored marines helping our dear apothecary would let you just walk away with the patient?

Putting aside any medical issues, Xepherial still has cronies with him, and they're armed and armored. One naked marine wouldn't be able to just walk past something like that. If they wanted to restrain you, all they'd have to do is hold you off long enough for him to cut through skull. Given it's a future saw made to cut through a space marine's skull, it wouldn't take extremely long to do that. Once that happened, the surgery would Have to continue, because even a space marine can't walk around with their brain on open display.
