Continuity mistake: When Assane gives his boy a gift, look at Claire's necklace when she starts getting defensive about the 'doctor's appointment'. The chain is caught on the collar and tucked all the way up next to her shoulder in some shots and normally down in a V in the rest. (00:07:40)
Visible crew/equipment: When Jane straight up tells John Swift that she's taking a "vacation" so she'll be out of his hair, just as Jane walks out of her own office, the red T-mark is visible on the floor at the doorway. (00:15:45)
