The Ugliest Dog in Hawaii - S1-E8
Other mistake: During the short action sequence with Magnum scaring off Steve and Mitch before collapsing, the lights go off for unexplained reasons; Mitch already ran off and past the guard, so he couldn't have switched them off, and in the fight nobody knocks lights down or bumps into switches. That aside, there's also an odd timing on the noise of the syringe falling, since neither Magnum or Steve appear to hold it in hand and Magnum punched free earlier. (00:12:10)

Other mistake: At the end of the episode, Zeus and Apollo are in a cage, and it is explained that it's because of sir Algernon's presence, due to Magnum's decision. It makes for a humorous finale, but does not make any sense; it's sir Algernon that has to be isolated for the 4 months quarantine, and an earlier segment implied that a fence had been built for him, as he needed to be limited in movements to avoid contact with the ocean and everyone on the estate.
