Continuity mistake: The exit door and stairwell outside of the town hall are shown to be at the very edge of the building when Proteus goes through it. When Xavier, Beast, Rogue and Wolverine use the same door and stairwell, the building suddenly stretches on for several more feet. (00:13:20 - 00:13:55)
Continuity mistake: When Proteus leaves the town hall, the door he exits is shown to lead into an alleyway. Moments later when Moira exits through the same door, it is shown to be leading into a corridor in the same building. (00:13:15)
Continuity mistake: When Xavier is speaking to Proteus telepathically, the position of his shirt and jacket sleeves go from being a few inches below his wrist in one shot, and then just slightly under his wrist in the next. (00:12:55)
Continuity mistake: When Moira is saying to Proteus "Kevin it's time to come home," you can see that Rogue is suddenly not wearing any lipstick. (00:04:05)
Continuity mistake: At the very end of the previous episode after Proteus had messed with Wolverine's sense of reality, Wolverine is shown whimpering in an open area. When Wolverine is shown at the beginning of this episode still whimpering, he has suddenly moved next to a treeline. Given the state of shock he was in, it's doubtful he would have gotten up and moved. (00:02:00)
