When Nick and Hank walk into the wooded trail Nick starts off wearing a red leather jacket with slots. Then the camera views a sky shot of the trees and when it pans back to them Nick has a brown leather jacket that was similar to the one he wore earlier on at the precinct.
When Nick and Hank are at the Police Station, Nick accidentally drops an engagement ring when picking up his jacket. Hank throws it to him overarm. In the next shot of Nick catching the ring, it is clear that the ring was thrown to him underarm from outside the camera shot.
When discussing the plaster cast of the boot print of the suspect, Hank shows Nick a printout of what the suspect's boot should look like.
The printout supposedly shows two pictures of the suspect's boot from two different angles but they're actually two completely different brands of boots.
