Revealing mistake: When Syd's Dad rescues her in the car park, he starts shooting at the other car. After firing one shot the slide of his gun locks back (indicating it's out of bullets), but when the angle changes he carries on firing with no problems. (00:43:20)
Continuity mistake: At the beginning when they show Meehan explaining that they're not going to jump because of fog, he is using his hands to emphasize the point, when they go back to the same point near the end of the episode, Meehan has his hands behind his back. (00:04:45 - 00:57:20)
Episode XXIX - Couple on a Train - S3-E3
Continuity mistake: When Josephine grabs Ezekiel by his poncho, she is wearing a black glove on her right arm, but when the scene cuts to Ezekiel when he says, "What business is it of yours?", the glove disappears, showing Josephine's arm bare, but in the next shot, she is wearing both gloves again.
