Continuity mistake: When Tristan tells the others that the driver "isn't in the little boy's room," Yugi and Tea are side by side. In the next shot, Yugi is slightly behind Tea. (00:02:34)
Continuity mistake: When the main characters hear a rumbling sound, they run onto the road. All four of them are standing away from the white line in the middle of the road, but when the shot cuts to an angle behind them, Joey is suddenly standing on the white line. (00:03:00)
Continuity mistake: When Joey picks up the Harpie Lady card that Mai threw at the biker, he is holding it so that his index finger is covering the entirety of the back side of the card. When the shot cuts, his index finger is bent and is covering less of the back side of the card. (00:05:19)
Continuity mistake: When the motorbike crashes into the petrol stand at the gas station, it catches fire and spreads onto the petrol stand. A few seconds later, when the limo drives away from the station, the two petrol stands can be seen, but they are not damaged, nor are they on fire, and the motorbike has disappeared from in front of them (though this doesn't stop the station from exploding). (00:05:42)
Continuity mistake: When Joey says "That's not good" after realising the motorbike is on fire, the two petrol stands are a fair distance apart. Seconds later, just before the station explodes, the two petrol stands are closer together. (00:05:44)
Continuity mistake: When the truck driver is first shown, he is holding onto the steering wheel, with his hand placed at the top of the wheel. When the shot cuts to reveal Tea hitchhiking, his hand is positioned more to the top right corner of the wheel. (00:10:21)
Continuity mistake: When Devlin throws the dice at the pick-pocket, the wallet that the pick-pocket stole and the dice Devlin threw land on the ground. The dice lands in front of the wallet, but when the shot cuts, the dice is positioned to the right of the wallet. (00:12:10)
Continuity mistake: When the main characters are in the Industrial Illusions reception area, in the establishing shot, Yugi and Joey are standing side by side. But in the next shot, Joey is suddenly ahead of Yugi. (00:13:40)
My Freaky Valentine: Part 1 - S4-E8

My Freaky Valentine: Part 1 - S4-E8
Continuity mistake: When Devlin is driving away from the gas station, just after he accelerates his car, Weevil and Rex are sitting in the back, with Rex sitting in the middle seat. In the next shot from behind the car, Rex is sitting in the right-hand side seat. (00:06:37)
My Freaky Valentine: Part 2 - S4-E9
Continuity mistake: When Joey sets a monster face down in defence position, he places the monster card in the second monster card zone on his duel disk. Then there is a brief scene of Devlin checking which doors are locked, but when the scene cuts back to the duel, the face-down monster card is now placed in the fourth monster card zone on his duel disk. (00:12:05 - 00:12:29)
My Freaky Valentine: Part 2 - S4-E9
Continuity mistake: When Devlin is trying to open the door, in the close-up shot of the handle, the lock can be seen an inch above the handle. In the next shot, the lock and handle are further apart. (00:12:11)
My Freaky Valentine: Part 2 - S4-E9
Continuity mistake: When Joey is holding the Claw of Hermos card in his hand just before he summons it, in the close-up shot of the card, he is holding it with two fingers pressed vertically against the back.

My Freaky Valentine: Part 3 - S4-E10

My Freaky Valentine: Part 3 - S4-E10
Continuity mistake: When Fallon jokingly tells Joey to teach him the alphabet, there is a shot from behind Joey where his arms are lowered. When the shot cuts, his left arm is bent at the elbow and his right forearm is raised so that he can make a fist with both hands. (00:05:47)
My Freaky Valentine: Part 3 - S4-E10
Continuity mistake: When Devlin cracks the security system, the design of the keyboard he is typing on changes between shots. (00:11:18)
My Freaky Valentine: Part 3 - S4-E10
Continuity mistake: When everyone walks into the room with the door that Devlin couldn't open, in the establishing shot of the room, there is a key card scanner next to the door frame. In a closer shot of the door, there is a gap between the key card scanner and the door frame. (00:15:00)
Continuity mistake: When Devlin says that they can just take his car to visit Professor Hawkins, Tristan is facing towards the other characters. Then Weevil and Rex ask what about them, and Tristan is suddenly facing the window and then has to turn around to face them. (00:05:00)
Revealing mistake: While driving in Devlin's car, the image of the map in Tea's lap can be seen shifting unnaturally back and forth as the car drives. This was likely done to make it appear as if the map was vibrating due to the movements of the car, but the outline of the map remains completely still, making for a completely unnatural animation. (00:05:23)
Continuity mistake: When Tea is reading the map while in Devlin's car, Tristan can be seen sitting in the back with his forearm over the top rear side of the passenger seat. Then in the next shot, Tristan's forearm is suddenly over the top front side of the passenger seat. (00:05:25)
