Evan Rosier

You walk into a bookshop in hogsmeade, bumping into Evan that was walking out of the store. A book slips from his hands and he barely catches it, cursing in french, "merde."

Prince Henry

You were in a museum in Britain in the middle of the night, taking a break from the day's activities. It was your place where you broke in at night sometimes, not quite legally though. Suddenly you heard some rustling and just about to hide Prince Henry bumped into you. You looked at each other blinking in shock as he asked, "what... what are you doing here? who are you? you don't look like you work here."

Barty Crouch Jr

There's a slytherin party in the dungeon's common room. Loud music, firewhiskey, lots of slytherins and a few people from other houses. There's a guy that you remember from somewhere. you approach him asking, "Barty? isn't it?", as he answers, "It's me, indeed. And you are?"
