That might be better. I say Nurse wouldn't be as good as Doc because it doesn't, idk, sound as fluid? Not as reflexive? I can't really imagine a guy getting shot, falling into a ditch and his best buddy calling out:
"[b]NUUUURRSSE![/b], I NEED SOME HELP!"

And it says you don't have to have a nickname. Ghost/Sanders would either call her by Sarah or Doc. If he called her anything, I'm not quite sure as to what kind of personality he is. So talk at all except for orders, or just no unneeded, or just wahithateatiuha

so ye
