As Helena has bad motor abilities and isn't used to dance, she does awkward moves and misses the beat when the clone sisters and Felix dance at his loft. In contrast, Helena dances amazingly well at the underground club owned by Olivier in Parts Developed in an Unusual Manner (2013), with Olivier's tail in her hand, which she cut off earlier.
Paul and the members of his unit commit a number of errors in the way they wear the US Army Combat Uniform: 1) The mandarin collar is never worn "up." The collar should be worn "down" with the tab folded underneath the left side of the collar and secured with Velcro. 2) Assuming the show takes place at the time of airing, the black beret is no longer worn with the Army Combat Uniform. The patrol cap should be worn instead. 3) Assuming some circumstance that would create an exception for the second error, all of the berets are worn incorrectly. Paul, as an officer, should have his rank insignia pinned and centered on the blue "flash," while the enlisted men with him should have their unit's Distinctive Unit Insignia pinned and centered on the "flash." In addition, the berets should be formed to the heads of the Soldiers wearing them and "shaved." 4) All of the Soldiers appear to be wearing pistol belts, but none of them seem to be wearing side-arms. 5) If Paul's unit is a special operations unit, he and his Soldiers should be wearing the US Army Special Forces Command Patch or the US Army Special Operations Command patch, not the patch shown. 6) At least one of the Soldiers is wearing a Velcro name-tape on the right side of his US Army Combat Uniform, but not a US Army tape on the left side over the heart. 7) The subdued American flag patch the Soldiers wear is an unauthorized variety of the patch (it should be full-color or a subdued infra-red plastic version of the flag), and is also worn too low on the right sleeve. The patch should be placed on the top flap of the pocket, not on the pocket itself. 8) As a Veteran of the Afghanistan Campaign, Paul should be wearing a combat patch under the American flag patch on his right sleeve. 9) Every single error prior to this one is irrelevant if the show actually takes place in Canada, where it would be generally illegal for US Army personnel to be wearing their uniforms in public outside of a Canadian Military facility. Under international law, this could be considered an invasion of Canada by the United States.
