Factual error: In the beginning a woman is counting brown 200 Euro banknotes. 200 Euro notes are yellow.
Factual error: The grave stone in the cemetery shows the deceased rank as 1st Lieutenant, but the branch of service is U.S. Navy. There is no such rank in the Navy. The rank for an officer 02 is Lieutenant Junior Grade - Lt.Jg.
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).
