Continuity mistake: When Magnum is pouring beer and tomato juice in the blender, bottle and can switch hands - look at the blender's jar and its handle. (00:14:20)
Continuity mistake: Magnum is dosing tabasco into the thing his girlfriend makes him prepare; notice he's wearing his team ring with the proper orientation (two arms of the cross of Lorraine closer to his hand). When he pushes the button of the mixer, the ring is upside down. (00:14:40)
Continuity mistake: Magnum is following the icky instructions for a protein drink left by his unseen girlfriend with the golden voice. Somehow from eggs, flat beer and tomato juice, the result is a green mix. He is blending it in close-up on the table (the wood texture is a tell), but he recovers the goop from a different piece of furniture with a sink. (00:14:40)
Continuity mistake: During his scuffle with TC, Magnum is wearing the same white tennis shoes he was wearing in the ship scene in some shots (closer angles generally), and dirty, chunkier sneakers in others. (00:36:40)
Continuity mistake: Frustrated by Joey's deception, TC tosses the bag of heroin on the dresser, and it ends up on top of a box. In the next shot, it changes position, being off the box. (00:40:25)
Continuity mistake: During their fight, Magnum in a close-up slams TC on a table. A chair is lying on the floor by the table; that chair will be toppled over only in the following shot. (00:37:00)
Continuity mistake: The foul concoction Magnum prepares based on his girlfriend's recipe fills the glass at a different level depending on the angle before Rick's arrival. (00:15:00)
Continuity mistake: Approaching the ship at the beginning of the episode, TC's chopper is the N58243 model, with the flotation skids. When he actually lands on the bridge though, it's N1095A. (00:02:05 - 00:03:00)
