Continuity mistake: In the original show we are led to believe that Lorelei lost her virginity to Christopher. But in this, during the late night gathering outside after the funeral, Lorelei's story about her father was about her losing her virginity to someone who wasn't Christopher. She got pregnant at the age of 16. We are to assume that she did not sleep with anyone immediately after Christopher. If the above is true, she didn't get pregnant when she lost her virginity. If she didn't get pregnant then she should've been safe with Christopher. What did the above were true, we would have heard about it. She would have told her daughter about how she lost her virginity.
Continuity mistake: Christian is wearing a blue polo shirt, standing outside the luxury van in which Letty and Javier are being held captive. When he gets in the van, from that point on he is wearing a tan jacket over his shirt.
Revealing mistake: Right after the scene in Wallace's office where the DHS tries to shut down Hayes' investigation, the scene shifts to a montage. Towards the end of it there's a loop: in the bottom left corner you can see someone on a scooter appear from the left, only to disappear a second later and reappear from where they'd come the first time.
