Identifying The Character Types In My Film

There are two characters shown in the opening sequence of 'Rupture', who appear to be a certain character type, but the rest of the film would reveal otherwise.

The Villain
This is the girl in the sequence because she is the one holding the guy hostage. However in the film itself the guy could also be the villain because he killed her sister.

The Hero
This is also the girl who is trying to bring about revenge and justice for her sister's death.
