Hiiiii Francy-pants. Yes, that is what he will start calling you Javert and you may just have to deal with it. Prussia likes him. He's cool, he's ex-military, and he's from back in the day when Prussia likes to pretend he was the most amazing thing ever so LET HIM CONTINUE TO FIB A BIT ABOUT THAT. It surprised him how much he enjoyed chatting the guy up at first, but Prussia thinks if he likes it, he may as well keep doing it. Expect more of him Javert--to the point he'll probably be sick of him.
