Continuity mistake: Near the start, the camera pans out to see the dome now covered in a layer of black. Outside of the dome you can see nice green fields, a small forest area, little houses and everything looks rosy. However a few episodes back the military launched a MOAB (mother of all bombs) and and the surrounding area was wiped out completely. (00:05:50)
Suggested correction: The entire left side of the dome is where the bomb blew up. Now if you watch back when the bomb hit the dome, picture the lake being to the north on the map. When Joe and Norrie were looking for Ange, and they were on the bench when the bomb hit, SW in the scene is a pretty close point to when they show the aerial shots of the dome.
The Red Door - S2-E9
Continuity mistake: When Pauline enters the dome through the lake, her hair and whole body is wet, when she enters the house her hair is not only dry, it is professionally styled. Maybe they were out in the sun long enough for Pauline's hair to dry but I doubt if they met a stylist along the way.
Suggested correction: All 4 of them were equally wet getting out of the lake; and all 4 of them were dry when they next appeared in the story - which could have been an hour or more later, depending on how far they had to walk.
And they met a hair stylist along the way?
Other mistake: The temperature is dropping and everyone is bundling up to stay warm, yet when talking to Melanie, we can see Pauline is still wearing her sandals.
Suggested correction: That's a choice by the character. I've seen many people wearing sandals throughout the winter.
Blue on Blue - S1-E5
Continuity mistake: At the end of Outbreak, Big Jim finds Angie down in the bunker. Water is flooded everywhere (knee-deep), and Jim has on an orange buttoned long sleeve shirt. When this episode starts, at 2:15 the water is practically gone, and Big Jim is in a blue short-sleeved polo shirt. (00:02:15 - 00:40:15)
Suggested correction: Jim shuts the door when he discovers Angie, then he comes back the following day and that's why his shirt is different.
Other mistake: At the beginning when the plane is flying, it appears to crash into the dome from the outside. The curve of the Dome goes from the top right to bottom left and the plane crashes from the left so it is on the outside. But the wreckage falls down inside the Dome.
Suggested correction: The plane was always inside the dome. When we see Barbie and Joe at the dome wall, the camera angle changes to the opposite side. We see Barbie looking up at the plane as it crashes into the inside wall, which he wouldn't have been able to do if the plane was outside and in front of him.
