Continuity mistake: In the scene where Babe Ruthless is the jammer in the last seconds of her first derby she scores 4 points, as the announcer is telling the spectators, the shot goes to Babe skating around the track with arms in air, and the jammer star helmet cover she was wearing is missing. In the next shot she skates up to her coach and the helmet cover has reappeared.
Plot hole: From day one, you have to have insurance to even be able to set foot (skate) on the rink. You must provide your drivers license and sign a waiver. Minors have to have paperwork filled out by their parent/guardian. Bliss would have had to show ID to prove her age (she could have a fake, but people can spot those). She would have been busted her first day.
