If you stayed past the credits of The Amazing Spider-Man 2 this weekend, you may have gotten a peek at this summer’s highly-anticipated X-Men: Days of Future Past. In this brief sequence, Mystique (Jennifer Lawrence) helps save some fellow mutants, including Toad and Havoc, escape a military base.

It’s a moment that showcases a different mutant than we saw in X-Men: First Class and, according to screenwriter/producer Simon Kinberg, is representative of her arc in Days of Future Past. Teases Kinberg, “Is she going to remain the good, conscious human that Charles raised at the end of X-Men: First Class, or is she going to become the cold blooded assassin that we know from [the first] X-Men?”
