Well Im pretty sure Trey wont be as succesfull as Will... you really need to be special if you make everything fantastic, like Will. Even if Trey got his genes, its unlikely that one family can bring two or more geniuses. Trey is growing up with a superstar as dad, even if Will aint a normal star, you wont experience the same thing as Will did when he was small... you understand?
Maybe Trey should try to do opera instead :)
