Chapter 10: The Passenger - S2-E2
Factual error: The premise of the episode is that Mando needs to travel at sublight speed or else the fragile eggs will die. They need to travel to a nearby star system, though, not just a planet. Stars can't be too close together, so Mando is in for a trip that would take him literally years, which is not reflected at all by what is shown in the episode. (00:08:00)
