Other mistake: The license plate of the car used by Platt (93N-LI62) is the same as the one used by Charlotte Patterson in episode 13 (season 1): The Cyprus Agency. (00:01:10)
Other mistake: In a previous episode, it says that Phoebe and Max's ice breath can't touch or it'll freeze the whole city. In this episode they blow their ice breath at each other twice.
Other mistake: The URL seen on Siobhan's laptop (https://internet-search.comm7986/index.html) is obviously a fake URL.
Other mistake: If you look closely at the army of Rangers in the opening credits, you can see four versions of Tommy Oliver: Green Ranger, White Ranger, Zeo Ranger Red, Black Dino Ranger. Even though he had a single clone made, he can't be four variations at the same time.
Other mistake: In the credits for "Tests," the "created by" credits for the characters of Anarchy and Katana are swapped: Mike W. Barr and Jim Aparo are erroneously credited for creating Anarchy (when in fact they created Katana as part of the comic "Batman and the Outsiders" in 1983), while Alan Grant and Norm Breyfogle are incorrectly credited for creating Katana. (Grant and Breyfogle created Anarchy in issues of "Detective Comics" from 1989.)
Other mistake: Sky's dress has no bullet holes, although she was shot twice in the stomach.
Other mistake: When Rebecca is telling Dorn about Etienne's death, she explains that his room was right above the garage and after the explosion she "tried to go in, but the room was gone." Yet at the end of the episode when Louis goes into Etienne's room, it is fully intact, including pictures taped to the wall.
