Another violation of the real-time format; Sherry asks Julia where the cell phone is, takes off her coat, and then the camera immediately cuts to her in Alan's bedroom grabbing the cellphone.
Exterior shots show Sherry's car as a W210 E-Class Mercedes, but interior shots show the steering wheel and instrument cluster from the W220 S-Class.
Jack holds a gun on the pilot and tucks it into the waistband in the small of his back while in the cockpit. Next scene - when walking back into the cabin, toward Nina, he is once again tucking his gun into his rear waistband.
Jack, Chase and Nina head back to L.A. from Mexico in a C-130 Hercules aircraft. It takes approximately the same amount of time that it took to fly down on a personal jet. The Hercules is a prop driven plane and averages about one third the speed of a jet a/c and would have taken three times as long to fly the same distance, even at its top speed.
When Sherry drives to Alan's house, some crew members can be seen in the garage, left from the main building.
