Continuity: At the end, Solo & Illya land the helicopter on top of the furniture van. But after the shot of them in the cockpit bumping to a landing, a wide shot shows the copter still hovering in the air above the van. Cut back to them in the cockpit and they're landed again; back to the wide shot, still in the air.

Continuity: In Waverly's office at the beginning, the contemplative Illya's hand is draped over his glasses salute-fashion in wide shot. But in close-up, it's suddenly curled into a fist at the side of his head. Next shot, he's "saluting" again.

Revealing: Solo is driving on a country road through a wooded area with no street lights. So what are all those bright round lights reflecting on the hood and windshield of his car? UFOs?

Other: Solo seems to forget just who called whom when he calls Illya on the communicator. After Illya picks up, Solo answers as though Illya had called him instead.

Revealing: The stock footage establishing shot of Paris shows a gray, cloudy, overcast day. But in the next shot, on the streets, it's bright and sunny.

Continuity: In the stairwell, Illya shoots the second Thrush gunman one time. When the man starts to fall, there are no holes or marks at all on his white jacket. A few seconds later, as he finishes falling down the stairs, three bullet holes suddenly appear in his coat, even though Illya only shot him once.

Revealing: Solo pushes the chief from Calcutta's wheelchair into an elevator in UNCLE headquarters. The floor going into the lift, however, is visibly solid, with no break to allow for a real elevator's movement.

Revealing: U.N.C.L.E. headquarters must be full of elevators that don't go anywhere. When Mandy enters Solo's elevator car, she crosses a solid threshold with no break in the floor.

Plot hole: Mr. Varner spots Illya down the street and says, "I think he's another U.N.C.L.E. agent." His uncertainty is odd: he helped identify and chase Illya earlier in the episode, so he already knew to be fact what he only "thinks" in this later scene.

Revealing: Solo's stunt double's face can be seen several times during the fight scene in the Thrush garage.

Factual error: Mandy reveals at the end that she's been carrying the microdot hidden inside her contact lens. Ouch. Any foreign object placed inside a contact, especially the hard glass contacts of the 60s, would cause irritation severe enough to make the lens unwearable and the eye very, very red.

Plot hole: Illya dives into the pool to rescue Solo and Lavinia, who've been tied to mattresses and left to drown. Somehow, Illya divines that Solo will be able to free himself. He swims to Lavinia and cuts her free while Solo is still sinking, then heads for the ladder without looking back. Fortunately, his psychic powers are on target: an untied Solo soon appears, swimming free, behind him.

Continuity: In the hotel room, Solo gives Lavinia Brown one of his cards. She's holding it in her left hand and gesturing with it as she talks to him. But when the camera angle changes slightly, the card suddenly vanishes.
