When Logan is asking Veronica about asking Parker out, Veronica has her hair in a ponytail. From the front, it looks like she has some sort of tie around it, but from the back, the tie is gone.
(at around 26 mins) During Veronica's phone call, the phone keeps jumping back and forth between her left and right hands from shot to shot.
Veronica (Kristen Bell) discovers the bug in her phone in the sim card slot. No sim card can be seen when zoomed in on the phone which would make it impossible for Veronica to make calls.
When Veronica (Kristen Bell) is using the disposable cell phone and pretending to be calling from a radio station she has her phone to her right ear. A few seconds later the phone is to her left ear for just a split second, and then switches back to the right.
In the last scene when Veronica (Kristen Bell) and Keith (Enrico Colantoni) are having dinner, you see Veronica holding onto the side of the pot she's scooping the meat and potatoes out of. Having come off the stove, where it would have been at least keeping warm, it should have burned her hand.
Sacks (Brandon Hillock) mentions hearing from the LAX (Los Angeles International airport) and waiting to hear from John Wayne, another Los Angeles area airport. There are other major airports in the area. Burbank and Ontario airports are nearby. And, given the estimated amount of time elapsed, Long Beach airport would also be another possibility.
When Veronica and Tim are discussing western states, Tim mentions Wisconsin. Maybe he meant to say Wyoming.
Keith tells Professor Landry that a bag containing a bloody dress shirt was found, along with gloves. But actually it was a bowling shirt with Landry's initials on the pocket.
