Continuity mistake: All the action in this episode takes place on the same day, but Nicky is first wearing a brown jumper, then when her and the Sikhs stop for a break Nicky is wearing a blue jumper, then later on she is wearing a black one, with the same grey skirt and blue anorak.
Revealing mistake: Whenever Isis has to do jumps you can tell it's not her but a stunt double.
