Sky: Part 1 - S5-E1
Continuity mistake: The baby carrier little Sky is in as the group heads towards the car changes between takes. When they are walking down the driveway, it is open, and Sarah Jane quickly closes it when Gita comes up. Gita opens the carrier, to discover the baby, and Sarah Jane closes it again. There is more dialogue and Gita goes back to cooing at the baby. When did the carrier open again? Then the car alarms go off and if you look closely, you can see it's closed again, which is confirmed when the baby is handed off to Clyde.
Continuity mistake: (Season 2 Episode 2) Near the end, as the worms have died and exploded trying to spawn, a shot shows Cutter, Claudia and Stephen ripping the spawning worms from their bodies. Stephen is shown with one in each hand and another hanging on the right of his chest. In the following shot he is seen ripping one off his right chin, which did not have any worm on it in the previous shot.
Continuity mistake: In the episode "The Education of Jaime Sommers", when Jaime and Tom are having coffee, the size and position of cappucino foam on Jaime's nose changes from shot to shot.
