Factual error: The bomb is supposed to go off at the "DC Zoo", but the scene takes place at the National Botanical Garden, on the complete opposite side of DC from where the Smithsonian National Zoo actually is.
Factual error: Elizabeth takes a look at one of the passports, which on the outside is Swiss but the info on the inside corresponds to that of a German passport. (00:43:25)
Factual error: When Red goes to meet Zamani at the Lincoln memorial, he initially walks down the monument steps eastward, towards the reflecting pool in the direction of the Washington Monument and finds Zamani at the base of the steps. The map that is shown of his supposed location in front of the Lincoln Memorial when the FBI starts tracking him, isn't a map of the National Mall, nor the Lincoln Memorial. Later, when they are walking and he is "on the move, heading westbound", they are actually walking away from the Washington Monument, towards the Lincoln memorial, to the location where they had originally met (and discussed the Cherry Blossoms). Two seconds later, they are near 14th St, which is easily a 25 minute walk from the Lincoln Memorial. (00:33:25)
Factual error: The FBI logo on the projector screen is not the actual FBI logo. There are supposed to be 3 red stripes and 2 white stripes. There are supposed to only be 13 stars, 6 more have been added next to the scale. There are less than 46 leaves on what are supposed to be Laurel Leaf branches. [The differences can't be intentional, as "unauthorized use" of the FBI seal only applies where a situation might be construed to imply that the FBI approves its use, not the case in a fictional TV program.] (00:38:45 - 00:41:15)
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).
