Hellsing readers will recognize Heinkel’s wound as one sustained on the front lines in ’99.
Jon: What did you go and do that for?!
Heinkel: He’ll be fine. It would take far more than that to do any real damage.
Jon: That’s not the point! You had him under control — all tied up with those holy ropes of yours. He wasn’t a threat!
Heinkel: …Sir, have you missed the fact that half of my face is torn off?
His kind is always a threat.
