Other mistake: Julianne Klemm, the writer for this episode, has her first name misspelled in the opening credits as "Julaianne." (00:02:07)

Continuity mistake: When the Danger Room monster has ensnared Cyclops, the slime coming off its tentacles is green. When the shot changes, the slime is orange. (00:02:18)

Continuity mistake: When Gambit is asking why Cyclops wants his Danger Room session to be tougher, there is a microphone a few inches from his mouth. When the shot changes, the microphone has disappeared. (00:02:44)

Continuity mistake: When Gambit answers the phone, he brings it to his right ear with his right hand. When the shot changes, he is holding it to his left ear with his left hand, and he is also facing the opposite direction. (00:02:53)

Revealing mistake: When Gambit bumps the toggle switch that increases the Danger Room difficulty, you can see it actually moves itself before his elbow touches it. (00:02:55)

Continuity mistake: When the Danger Room doppelganger of Omega Red confronts Cyclops, its left arm is pointed down. When the shot changes, its left hand is raised at almost shoulder level. (00:03:01)

Continuity mistake: When the Danger Room alarm is beeping to notify Rogue that Cyclops is in danger, in the first shot, the control panel for the alarm consists of the screen and rows of buttons below it. When the shot changes, about half the rows of buttons have been replaced by what appears to be a phone. (00:03:57)

Other mistake: When Rogue drops the mug of coffee onto the floor, you can see that the coffee touches her boot, yet her boot does not get any stains on it. (00:04:05)

Continuity mistake: The amount of damage to Cyclops' uniform decreases. When his Danger Room session is first terminated, his uniform is mostly missing around his shoulders and chest. A few shots later, the aforementioned area of his uniform is not as torn up. (00:04:15 - 00:04:50)

Continuity mistake: The position of Cyclops' body changes when Jean Grey is cradling his head. At first, he is sitting slightly upright. When the shot changes, he is lying down. (00:04:40)

Continuity mistake: During Gambit's flashback, the chosen one for the Assassin's Guild is shown to be placing their tithe box on the stump of a tree roughly halfway between the center ring and the outer edge. When the shot changes, the tithe box has suddenly moved to the center of the stump, and the tithe box itself is suddenly wider and shorter and has rotated 90°. (00:05:00)
Other mistake: When Gambit is wiping sweat off his forehead, the locks of hair that he is rubbing his fist against do not move. (00:05:20)

Continuity mistake: In the flashback when Gambit runs up to two of his fellow guild members to tell them the others are almost there, he runs up to the one in the blue vest. When the shot changes, he is suddenly facing his brother Bobby. (00:05:21)
Continuity mistake: When the chosen one for the Thieves Guild is called forward to present their tithe, the chosen one for the Assassins Guild can still be seen kneeling before the External. In the next shot when the chosen one for the Thieves is shown arriving on the scene, the chosen one for the Assassins is suddenly back to standing among the other members of his guild. In the next shot, the chosen one for the Assassins is back to kneeling before the External. (00:06:00)
Continuity mistake: When the chosen one for the Thieves Guild tries to present their tithe to the External, he is shown walking right up to the tree stump where he was to have placed the tithe. When the shot changes, he is still walking forward, and therefore should've bumped into the stump. He is saying a line of dialogue as he is walking forward, so it can't be considered an action shown from a different angle. (00:06:15)

Continuity mistake: When the chosen one for the Guild of Thieves drops his tithe box, it lands on the inside of his right foot. When the shot changes, the box is suddenly equidistant between his feet. A couple of shots later, the box has moved away from him, resting next to the tree stump. (00:06:17)

Continuity mistake: When Bella Donna is being selected as the chosen one for the Guild of Assassins, she is flanked by three of her guild members. When the shot changes, the three guild members have disappeared. (00:06:49)

Continuity mistake: When the External selects Bobby to be the chosen one for the Guild of Thieves, she turns his jacket red and his gloves gray and fingerless. When he is shown again a few shots later, his jacket is now green, and his gloves are brown, with only the thumbs being fingerless. (00:06:53)
Chosen answer: It says MPO "First Exemplary Printing House" which is a real printing company in Russia founded by Ivan Dmitrievich Sytin in 1889. There seems to be something about "named after..." as well.
