When Charlie and Mike first meet and have their gun standoff, Charlie draws her gun and they do an exchange of guns and a 20 dollar bill. In the over-the-shoulder shot, Charlie has the bill, but in the wide shot, and for the rest of the scene, it's in Mike's hand until she snatches it.
When Mike is undercover with Felix, when he enters the house, his sweatshirt is black, but when he goes out to the truck of jeans, his sweatshirt is maroon.
