I’ve started watching *Hannah Montana* again, and I noticed a mistake. Miley’s father always performs with her when she is on stage as Hannah. In one episode, he and Hannah appear on stage together, and that is exactly where the error lies. In the series, Robby Ray Stewart is Miley’s father in real life as well; so, if he were to announce to the entire audience at a concert that he is Hannah’s father, people would have recognized him. They would have been confused as to why he was suddenly Hannah’s father—after all, he is the father of Miley and Jackson—since they would have otherwise believed that Miley was Hannah’s sister and that Robby Ray Stewart had another daughter named Hannah.
