A student who is at the top of her class, works in the laboratory where it all starts, and works out who Spider-Man is before he tells her.
The two Amazing Spider-Man films give Gwen Stacy a great deal more to do than this material usually gives the person the hero is in love with. She is scientifically literate, she is ahead of Peter Parker for most of both films, and her decisions are the ones the plots turn on.
That is also what makes what happens to her land the way it does. She is not in the room because somebody took her there.
