Quote - The current storyline calls for brother & sister heroes referring to Quicksilver and the Scarlet Witch, which were pivotal members of the Avengers.  If the moviemakers are literal to the comics, it would be the first introduction of mutants to the team.  Especially since Wanda and Pietro are the prodigies of Magneto himself.

Could add to the drama, since they are Mageneto's children, and their loyalties come into question from time to time.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
