Other mistake: Cook and Effy manage to fall through Pandora's Mum's wardrobe, into the next door neighbor's bedroom. But this is not possible as the neighbors' houses are detached.
Visible crew/equipment: At the end of the episode, after Cook's father has been pushed off the boat, there should be only 4 people left on the boat (J, Freddie, Cook and Effie). However there is a camera man sitting behind Freddie inside the opening to the hull (you can see their arm/hand and camera lens).
Continuity mistake: While Sid is reading the messages from Effy and Tony on his phone, Effy's name is spelt 'Effie'. However, in the next shot it is spelt 'Effy'.
Visible crew/equipment: When Cassie is picked up from the hospital by the taxi, you can see a crewmember reflected in its window.
Visible crew/equipment: Green screens and crew reflections can be seen in Sid's glasses multiple times.
Visible crew/equipment: When Naomi and Emily are standing by the water watch carefully, after Emily says, "It's one of my favourites," you can see a camera at the right top hand corner. It is visible at least 10 seconds so you shouldn't miss it.
Continuity mistake: When returning the coffin, Tony and Sid leave the boot of the hearse open. Moments later it has shut itself.
