I'm not sure I know why "Justin as artist" means so much to me.
Yes that. If Justin were just as smart and brave as he is now, and just as passionate about being a lawyer or a businessman or a whatever, why wouldn't he appeal to you as much? Is it his age that makes art seem more likely?
And I'm not disagreeing, I'm just curious about why it's so important to you. Though you did agree that Brian would still be attracted to Justin for his genius and bravery and passion, even in another field, yes?
