Character mistake: When trying to teach Banshee to fly, he is told to make his sound waves super sonic. Sound waves cannot be super sonic. Sound can only travel at the speed of sound, it always does. I guess they were trying to tell him to use a very high frequency, but the speed would still be the speed of sound.

Factual error: The establishing shot of Shaw's boat says they're in Miami. Yet in the scene, we see a very large suspension bridge in the background. The bridge is the St Simons Bridge leading from Brunswick to St. Simons, Georgia.
Erik Lehnsherr: I've been at the mercy of men just following orders. Never again.

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.
