Kristen Stewart: It's the first where you feel you're not watching the story of, 'Are they going to stay together? Are they not going to stay together?' They're done, it's very official. And the beginning is really happy - like, it's the happiest the series ever gets, it's really light. They know each other now in a much more realistic way, they are not just enamoured with each other, they are really able to live. And then it all gets crazy after we have sex because that's just what happens, kids.
Robert Pattinson: Use a condom! That's the moral of the movie.
