DAMMIT PEOPLE I'M TRYING TO GET GRANT ALL INJURED AND FUCKED TO MAKE EVERYTHING ALL GRITTY AND SHIT, AND YOU ALL COME DIVING IN AND ARE LIKE "MAAAAGIC WEEEEEEEEEEEE".
The only abnormal thing about Grant's really just his insanely high pain tolerance and willpower; aside from that, he's just just a guy capable of patching you up good or delivering you a large can of whoop-ass.
