Natalie Luca (No. 184) - S4-E12
Continuity mistake: In the scene with Tom, Reddington, Dembe and Agnes; Dembe is playing with Agnes in her cot while Tom and Reddington talk. Dembe later picks up Agnes and puts her on his knee, only for her to return to her cot mere seconds later.
Natalie Luca (No. 184) - S4-E12
Audio problem: At the end of the episode when Reddington goes to see Natalie Luca (behind glass), he tells her that the woman she killed at the massage parlour was an associate of his. When Natalie says "She said if I didn't kill him, she would tell Hawthorne where to find us", her lips don't match what she's saying in the reflection of the glass.
Answer: The man Red killed, Sam Scott, was Lizzie's adoptive father, not her biological one. However, at that time Lizzie (and thus the audience), was led to believe her real father abandoned her and her mother, so expect more secrets to be revealed how her real father actually died (or if he's even actually dead).
