Episode #4.1 - S4-E1

Episode #4.1 - S4-E1
Continuity mistake: Camille and Humphrey pass to each other and show Andre Morgan the key retrieved from the safe. They hold it positioning their fingers differently (tip of the key or closer to the rounded part) on the various shots. (00:18:50)
Episode #4.1 - S4-E1
Continuity mistake: When Dwayne speaks with the mysterious woman at Catherine's, her hair looks different in close-ups and wider angles. (00:19:50)
Episode #4.1 - S4-E1
Continuity mistake: Dwayne realises that he did not ask the cute girl's name, and looks at her now far away. Something is wrong with this shot of Joséphine Jobert and her derriere; walking down the same street there's the same couple that is having a drink right next to Dwayne (his black shirt with colourful drawings is not exactly hard to miss). (00:20:50)
Episode #4.1 - S4-E1

Episode #4.1 - S4-E1
Continuity mistake: Humph and Camille are talking with Zeta Akande about the reasons for the lack of references from her job. When she says "The children really loved me", her braids at the leftmost side of the chest are bunched together, split when she says in close-up "He didn't like that", united again as it gets back to a wider angle, etc. (00:32:35)

Episode #4.1 - S4-E1
Continuity mistake: When Humphrey sets the popcorn for Harry, Harry in the last shot is closer than in the previous - which could make sense if we assume he scuttled closer during the split cut to Kris Marshall, but the light on the couch changes between shots as well. (00:51:15)
