I have Markus/Mark Green, multi personality disorder.
He is a 6th year ravenclaw - but loves to come out of the common room with a book. Markus prefers the student hang out (and choosing a dark corner in it.)
.Bad at anything when it comes to books/classes
.not a very social person...He's more rugged and often confused for slytherin due to it.
.Protective of those he does bond with. (can be protective of those Mark bonds with during golden)
Shy, but not needy he isn't one to cling to anyone, preferring his books.
Untrusting but kind, he is one of those who would give the shirt off his back.
Basically ahead of his classes - every class due to his bookworm habits.
Can make friends, and once he does check in from time to time (When he's in control.)
I will say Mark even in forums other than golden is NOT into men. (my character Shiro and Hiro are but there not an option.), though in all actuality Mark's not into man or woman that way - stunted in personality and stuck in child form. Markus is all for girls and women, but I would be willing to make both of these personalities a friend. (At the very least Mark.)
