You! I've decided that when Addy and Arthur meet up, maybe in next period, that they'd interact and she'd imprint on you and see you as an older brother to her. Like, cling onto him and whatnot, cuz her older brother was intimidating and over-protective of her when she was little, and I can see Arthur being like that as well.

Also, if Addy's brother were to ever come into this rp, he'd be something like a stereotypical Japanese gangster or a greaser, pompadour and all. He'd be a total jerk to anyone who gets too close to Adelaide, but would dote on her and worry. xD
