One character development that isn't a secret in the upcoming X-Men: Apocalypse is the revelation that Quicksilver (Evan Peters) is revealed to be the son of Michael Fassbender's Magneto. Not only isn't it a mystery, it's actually revealed in the final trailer for the movie.

What movie does Quicksilver tell Magneto?

Peters was first introduced as the speedster in "X-Men: Days of Future Past" where he rescued Erik from a prison cell under the Pentagon. During that rescue, he unknowingly mentions how the two could be related. "They told me you control metal," Quicksilver says to Magneto.

Does Magneto find out that Quicksilver is his son in Dark Phoenix?

The new sequel in the franchise - X-Men: Dark Phoenix - will not feature Quicksilver/Peter Maximoff (Evan Peters) revealing himself as the son of Magneto/Erik Lehnsherr (Michael Fassbender) to his father.
