Character mistake: When Jenny is dead, Ellis attempts CPR on her, but his hands on her chest are far too high; they should be just up from the base of her sternum, his are nearly under her chin.
Character mistake: When in the car both are talking about a scar on his back. He is telling her he was in Serbia chasing a man all over the tundra. Mistakenly thinking of Siberia instead. (00:41:13)
