Following the Magic Kingdoms story, Isabela and Luisa have a mission trying to get into Isa's room and, since Bruno is the next character to be unlocked, I thought the poor guy would show up and find this.
Apparently it's not, but it was a funny thought and I decided to sketch it while I was in class.
Finally! (Well outside some comics; there's one where he has a nephew) Disney's animated version of Frollo makes a reference to having a brother (Jehan) in Disney's Magic Kingdoms game.
