Continuity mistake: When Rogue and Gambit are playing pool, Rogue's arms are bare from the elbow down except a yellow wristband on each wrist. When Beast comes in with the mail, Rogue is wearing her usual green sleeves and yellow gloves. (00:04:00 - 00:05:10)
Continuity mistake: Cocteau's tombstone has gained a gold plate on the front of it by the end of the episode. (00:01:35 - 00:19:25)
Continuity mistake: When Red Skull is leaving Wolverine and Captain America alone, he sets Captain America's shield on a table and Wolverine is shown to be hanging from stocks by his wrists with Captain America on his left and the table on his right at roughly a 45 degree angle. In a wide shot after Red Skull has left the room, the shield has vanished from the table and Wolverine is now several feet from where he originally was, with Captain America roughly at his 12 o'clock and the table roughly at his 3 o'clock. (00:10:45)
Continuity mistake: When Captain America says "Red Skull, wait!", his sleeves are entirely blue whereas they should be white from the mid-bicep and down. (00:10:45)
Continuity mistake: When Wolverine and Captain America first find Cocteau, the white ring on Captain America's shield is colored black in a wide shot. (00:08:45)
Continuity mistake: When Wolverine and Captain America start running, they are standing very close to each other. When the shot changes, they are several feet apart. (00:06:50)

Jubilee's Fairy Tale Theater - S5-E9
Continuity mistake: When the caverns start to tremor, the book that Jubilee was holding beforehand has vanished, then reappears, and then disappears again. (00:02:00)
Continuity mistake: The amount of bandages on Beast's torso vary depending on the shot. (00:14:35 - 00:19:45)
Continuity mistake: When Arkon states that Storm is the conqueror of his heart, he is holding up a goblet with his left hand and extending his right hand towards her. Not only is the bracelet on his right hand gold when it should be silver (the bracelet on his left hand remains silver in this shot), but his right hand looks rather effeminate. Arkon and Storm were sitting right next to each other and no one was shown to be standing between them in any other shot, so the right hand in question couldn't have belonged to another person. (00:16:40)
Continuity mistake: The character that says "We are saved" suddenly has gray-colored skin in the next shot. (00:18:00)
Continuity mistake: When Storm throws her communicator and the portal-opening orb on the ground for the other X-Men to find, they land right next to each other. When Jubilee finds the communicator, the orb is missing until the shot changes. (00:06:40 - 00:08:10)
Bloodlines - S5-E6
Continuity mistake: The yellow vertical line on the left side of Jubilee's shirt suddenly moves to the right side when she asks about Mystique's fate. (00:18:20)
Bloodlines - S5-E6
Continuity mistake: When Graydon Creed is struggling with Nightcrawler, his tie falls out from behind his jacket. In the next shot, the tie is back in its original place. (00:11:30)
Bloodlines - S5-E6
Continuity mistake: When Rogue is talking to Wolverine through her watch communicator, in the closeup shots the watch is shown to be around her glove, on her wrist. In the wide shot, the watch is either around her sleeve just beneath her glove or it has disappeared entirely. (00:09:00)
Bloodlines - S5-E6
Continuity mistake: When the Friends of Humanity member answers the door after Jubilee knocks, the floor is shown to be made up of square slabs. After Nightcrawler knocks him out, the floor has changed to a completely solid finish. (00:07:55)
