Continuity mistake: After his mother is shot, Erik squashes the bell on the doctor's desk. Its shape is completely different in all subsequent shots. (00:07:50)
Continuity mistake: When the young mutants are showing each other what they can do, they all have a glass of cola, all four sitting on a corner of the table. But when Banshee wants to show what he can do, the glasses are instantly lined up. (00:51:00)
Continuity mistake: Erik meets two Germans at the bar in Argentina, a pig farmer and a tailor. The amount of beer in the farmer's glass increases after Erik walks towards him. (00:23:20)
Continuity mistake: The Nazi doctor shoves a coin towards the edge of his desk, telling young Erik to move it or he'd shoot his mother. In a shot from behind the desk, the coin is much closer to the edge than in other shots. (00:07:15)
Continuity mistake: When Erik is first attempting to lift the submarine, he'd using his left hand. In subsequent scenes, specifically when Riptide turns into heavy wind to break Erik's grasp, he's now using his right hand.
Chosen answer: He's not okay with it, but he knows that Erik's views appeal strongly to her. To all intents and purposes, she's already made her decision - to try to stop her would likely only lead to an argument, which is not how he'd want them to part. Plus there is the somewhat major side issue that Charles has just been shot, so it's not really the right time for a discussion on conflicting mutant philosophies.
