Continuity mistake: Rey grabs BB-8 and her staff, and then jumps up onto a fallen AT-AT Walker. She turns to look at the Nightwatcher worm and is standing right next to a very slime covered BB-8 on top of the AT-AT with her hand on his head. It cuts to a shot of the Nightwatcher from over Rey's shoulder and then back to a frontal view of her again from a higher angle. Rey didn't move once during those shots. But now she's suddenly standing further away from BB-8 to show the junk part between them, BB-8 now has much less slime on him, and the groove in the metal of the walker going down vertically behind BB-8 has vanished.

Continuity mistake: When Danny and Ward meet Joy in her new place, Ward says "who was it who said I was being childish?" Danny is in the background, holding the folder cover open with his left hand. Shot cuts as he speaks, and his hand's suddenly on the pages with the folder cover hanging down loose.

Revealing mistake: The flipped ambulance at the beginning of the episode does not have a drive shaft. (00:03:09)
