When Tasha says to head upstairs for movie time, Chase, Adam and Bree start to run upstairs with grins on their faces (and with Chase's hands clenched into fists), but when the scene cuts to a different camera, the three are merely walking and only smiling, with Chase's hands in his pockets.
When the Davenports are first seen watching a movie, Adam's arm lies across Bree's legs to gather some popcorn from the bowl on Chase's lap, but when a different camera takes over, Adam's arm is pulled in to his chest with him now eating popcorn out of his hand. Bree is also different. She was eating popcorn from her right hand, but at the camera change she eats from her left.
In the show parallel universe Davenport says that parallel universe Tasha only let's him stay in the lab, yet when Leo arrives in the parallel universe he is no where to be seen.
