I'm sure he and Emma are well-acquainted. Brian might've met him, certainly. Troy has heard of him, no doubt. He's all for mutants in the media. Dazzler might have met him at this point, and she definitely knows about him. I know they're in different leagues, musically. I bet Zap is a fan, yay music enthusiasts. Shaw, obviously. He and Brian should interact sometime - maybe during the gala. They're both hams, lol. :P
