oh no i totally get that teens sneak into clubs, that wasn't my point. Just trying to say that generally, royalty going clubbing is the stereotypical example of a paparazzi field day, and Brion being 15 would make it all the better of a story. Brion would have to show his ID to get in, which would clearly show his identity and that he's underage. So either the club turns him away at the door, lets him in and faces the consequences, or he uses a fake ID.
So my mind immediately went to the idea of a teen-specific club. Hence my confusion
