Revealing mistake: When Nicky says she wants to get to France as soon as possible to find her parents you can see a vehicle moving in the distance.
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.
Continuity mistake: When the Sikhs turn their carts round after Nicky tells them not to go through the streets, the angle changes and Nicky and Kewal (in the green shirt) have changed positions. Also a blue Austin 1100 parked behind them appears and disappears between shots.
Plot hole: During "the changes" people fear machinery, but the woman who pulls back her curtains to watch Nicky and the sikhs go past is wearing a watch.
