When Bree steps in close to Robot-Bree, her foot begins to disappear in a glare upon the floor of the special effects overlap.
When Tasha says "limb from limb," the shot changes to a different camera and the body positions of Robot-Chase and Robot-Bree change as well: Adam had been looking toward his right, now he looks left, and Bree had her head tilted to the right, but now her head's held straight up.
When the super-teens, pretending to be robots, are eating in the kitchen, Leo tells Tasha he thinks it would be a good day to take the robots to school. The camera changes when Bree reacts by saying "yes!" and Adam's bread has suddenly changed from being two small pieces held one in each hand to a large crescent-shaped slice held only in his left.
When Robot-Adam flicks Leo's head, Robot-Bree can be seen cracking a smile just before the camera changes. However, this could be part of the robots being programmed with the real deal's "core personality traits."
