Steve Trevor and Diana

Their relationship is not at all settled. Steve Trevor is seen teaching Diana how to dance "“ something that comes in handy later on. And, as all men do, he believes that he is the one leading. Surprise! He isn't! When he doesn't agree with Diana's plans, she simply tells him that he has no say in it. She has already decided.
And this is more than just empowering. Wonder Woman is the strong female able to walk in the No Man's Land, and she is also the strong female who positions herself at the same level (or even higher) as the man. She takes the lead on, as well as off, the battlefield.
And she sets an example, which is even more obvious in the scene featuring Etta Candy, Trevor's secretary "“ or rather, slave, according to Diana.

This movie will kick all sorts of ass when it arrives!
