In the pivotal jogging scene, Cole runs past the transformers then the house with the flag. But when his phone dies, he turns around and runs back the way he came. Only instead of the sequence being reversed, he runs past the transformers first again and then the house.
The headphone on Cole's left ear during his call service is either off/on his ear between several shots.
After the bathroom fight, Zoccoli goes from lying on the floor to sitting against the wall in an arbitrary amount of time; James Reid appears to be unphased by this rapid man-oeuvre.

James and Cole, at James' house, happen to wake up at the same time after their hangover.
