My character punches yours in the face? What made this happen? Riodan won't throw punches unless he's out of options so clearly shit getting real.
Man, I don't even know. Accidental punching during sparring? In which case Fort would be initially surprised and then really amused. Especially if she got an injury out of it which lasted a day or two.
Riodan would laugh it off and then playfully tease her about it if the results left a mark.
Hey! I wouldn't operate on you if I wasn't sure of what I was doing! (Or at least, very enthusiastic at finding out! 
)
)
I would be scared to find out
Virgil has probably been talking a little too openly about doomsday devices and all the people he could potentially wipe out, someone overheard, and he got punched. He knows he deserves it, but he'll probably

Oh man, that's okay more chloroform and he'll stop taking swings. 
Pythonmelon: Well Nev more likely to give a slap, but she'll slap hard if punches are coming her way.
He wouldn't punch Nev, at least not hard. he doesn't like being hit for what he considers his genius
