Continuity mistake: When Rey jams her staff into the sand worm's mouth, she and BB-8 turn around and run back the direction they came from. With that first shot showing a second trail in the sand, BB-8 is leaving next to the trail he made already. Two trails. Then, when the sand worm slams down to spit Rey's staff back at her, that shot shows BB-8 and her still running the direction they came from, but now there's only one trail behind BB-8, the new one he's leaving now. The old one has vanished. (00:01:14)
Continuity mistake: Just before Rey jams her staff into the worm's mouth, she pulls back with her elbows out. In the next shot, suddenly her arms are in a completely different position with both elbows down. (00:01:07)
Continuity mistake: When the worm rears up in front of Rey, there are horizontal lines on its underbelly. One of which is very near the jaw and intersecting with the "shoulder" of one of its little arms. In the shot where it's about to snap at Rey before she wedges her staff into its mouth, the topmost line has vanished. (00:01:06)
Continuity mistake: BB-8 and Rey watch the sand worm go away after she feeds it and you can see BB-8 with the slime on him. It cuts to a different angle just before the droid asks her how she found him, and the slime spots on the side of his head change shape and size. Most notably the middle spot shrinks significantly and the bottom one over laps the edge of his head. Also between cuts Rey is suddenly much further back from BB-8. (00:02:25)
Continuity mistake: The piece of junk that Rey feeds to the Nightwatcher worm appears between her and BB-8 with the pointed end of it facing away from BB-8 towards Rey, with the round end pointed out. When she bends down to pick the junk up, in the close up the pointed end is now facing outwards from between her and the droid with the round end towards BB-8. (00:02:10)
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. (00:02:05)
Continuity mistake: As Rey is retrieving her staff with a slimed BB-8 in her grasp, she passes by and leaps onto the leg of an old fallen AT-AT Walker which is next to her. There is a fin, or toe, sticking up into the air from its foot with a groove down the middle in the close shot as she gets her staff. In one of the following shots as she's jumping up onto the leg, that middle groove on the toe disappears. Also in these shots, suddenly much more sand is built up against the foot of the Walker than before. (00:02:00)
Continuity mistake: The nightwatcher worm comes up out of the sand right next to BB-8's trail through the sand. After Rey identifies it and the creature is about to duck down under the sand, the trail BB-8 left behind has vanished. (00:00:45)
Continuity mistake: For most of the episode, Rey's outfit is shown having long pieces of fabric or cloth hanging off the back of her clothes like robe flaps and one in a sort of loop. Usually, when she's running or moving, these are flapping or blowing around behind her as you'd expect. Yet strangely, when she's running up to the spot where the sandworm just grabbed BB-8 and went under, the flaps are staying in front of her legs as she runs, but as she stops and the camera cuts, they are behind her again. (00:01:34)
Continuity mistake: In the very first shot of the episode, Rey and BB-8 are walking in the sand, and she is coming up on a giant sand dune to her left before her. Other large sand dunes are also visible in the background. Yet after that first shot, none of the massive dunes are ever seen again, and when they encounter the sand worm, all the dunes around them are significantly smaller. (00:00:23)
Continuity mistake: When Rey catches BB-8 and then runs, she scales a downed AT-AT Walker to get to safety. She runs up one of the Walker's back legs and stops at the top. Then, a couple of shots later, when the sand worm is looking up at her, suddenly the Walker's head is now in the direction she just came from. (00:02:14)
Continuity mistake: After Rey gets on top of the AT-AT safely away from the sand worm, she is holding BB-8 in her arms. He's covered with blue slime in several spots. In the next shot, when she sets him down, the large blob and smaller blobs on his head suddenly become one, and then the slime on his lower body is significantly more. (00:02:07)
Continuity mistake: When Rey is carrying BB-8 and running to grab her staff, then across the AT-AT leg, the heart-shaped lines on BB-8's "face" have disappeared. (00:02:03)
Continuity mistake: Just before the worm bursts up from the sand in front of Rey, BB-8 is running away and then stops looking forward. In the shot with him alone, the yellow rectangle next to the heart shape on his face is lined up so the edge of it is almost right above the left edge of one of the orange rectangles under it, with the white above the orange fully. Then, in the shot with him and Rey together facing the worm, the orange rectangle has moved further away so the right edge of it lines up with the white one, with more space between the two orange rectangles closest to his face. (00:01:00)
Continuity mistake: After Ray tells BB-8 to not move, we get a shot of them standing together. Suddenly, an extra line has now appeared on the heart-shaped part of BB-8's face going out from his eye. (00:00:39)
Continuity mistake: When BB-8 hears the creature come up from the sand behind him, he stops. Just before he turns around the orange rectangles on the left side of his face to being almost all uniform in shape and size, to now having two big ones on the ends and two small ones in the middle. (00:00:30)
Continuity mistake: As Rey tells BB-8 that he can stay with her, you see the droid behind her from a frontal view. When it cuts to a side angle of BB-8, the lines and details on the side of it's head close to it's "eye" change with more lines appearing, the orange rectangles at the bottom become taller, and the white rectangle box moves higher up. Also in the side view there is some black cone sticking out of what would be BB-8's "face." If it's his eye it's now suddenly sticking out way too far and isn't that extended. If it's the little censor thing that is next to his eye then it's now on the wrong side of his head. (00:00:25)
