Continuity mistake: When Kate goes to see the LARPers at the park to track down the trick arrows, her cross-body leather strap changes direction repeatedly. At first, it hangs from Kate's right shoulder to her left hip, but when Kate asks about the cop in their group, the strap hangs from her left shoulder. Then the leather strap reverts to the original way, only to switch yet again after the fist bump. None of the shots are flipped. (00:20:10)
Visible crew/equipment: After Raines shares details with Kellett about Semien's crew, when it cuts to Semien waking everyone up, just as he announces his contact with Belgian Federal Police, there's a visible T-mark taped to the floor behind Andre's cot. (00:24:25)
