Plot hole: At the end of the movie Deniro Sam says he was only in this to get to Seamus, and that he never left the CIA. But at the end of the car chase in Paris, when the BMW falls off the bridge into the construction site, Seamus and Deidre are injured, and knocked out, and dragged out of the wreck by the construction workers. Why didn't Sam just go get the incapacitated Seamus then? Or at least follow to see where Seamus and Deidre were taken for medical care?
Suggested correction: Because at that point he was maintaining the ruse that he was after the case.
