S1·E6 West Bound

Zeta and Roe flee on a train to avoid pursuit, and only Agent West manages to get on the train with them. Their efforts to avoid him are complicated by the fact that as the monorail train passes through certain electrical barriers, Zeta's hologram projectors go out of control, forcing the robot to change into different people at random. Despite this, the pair manage to escape and save the train after West's shots endanger it.
