Other mistake: Towards the end when we see one of the $100 bill plates up close, the plate is not of any money ever put into production in the US. While I know most movies do not try and use actual money, there are things that don't match how real money is made: serial numbers are not on the plates, circle around Ben's head doesn't go to the border, "The United States of America" is missing above the "100" on the left, just to name a few.
Other mistake: In the desert base camp, it is supposedly in the middle of the day or in pretty hot weather, but BA's breath can be seen in one shot.
Other mistake: In the montage at the end, Murdock is misspelled Murdoch on the military forms.
Other mistake: When Pike chases after BA by rappelling down (using his suit jacket and hand to do so), he uses the same rope Hannibal used to get into the building. Hannibal is seen with a rope bag and when he escapes into the building several stories below, he is seen unhooking but not throwing the bag out the window. Unless that had happened, Pike wouldn't have been able to use the rope to descend to the sidewalk.
Answer: Throughout the movie, Face has shown to be impulsive, and constantly deviating away from Hannibal's plan, in fact Face several times screws up because he hasn't followed the plan. Come the end of the movie however, and Face proves to Hannibal that he can tone down the impulsiveness, come up with a plan, stick to it, and see success, and Hannibal's comment to Face after he makes that plan are along the lines of "Good work kid".
