During the montage of the boys touring experience, while on the plane during the FIRST storm, you can visibly see the late teen/adult "Jermaine" sitting there. When arriving at the hotel they switch back to it being Jermaine Jackson II, playing early/mid teen "Jermaine." Late teen/adult "Jermaine" wasn't supposed to be introduced until the "Who's Lovin' You" performance.
When the group is singing"the love you save" they say Randy held your hand, when the line is Richie held your hand.
When Michael is singing The Love You Save, he says When Randy held your hand, the lyric is When Richie held your hand.
It is unbelievable and unlikely that Suzanne could not find one person who knew the lyrics to the national anthem in an airplane full of people on a domestic flight, let alone that she and Michael only knew the first two lines between them.
