As Whitaker's character doles out his guidance, we see this image of Jyn appear over his words: “If you continue to fight, what will you become?” The minute-and-a-half teaser trailer goes to great effort to make it clear that her character is an unstable element. There's no talk of the Force, or any of that familiar Jedi/Sith mysticism, but she is obviously someone who straddles both the light and dark. Is her appearance in the uniform of a Death Star gunner or TIE Fighter pilot a sign that she could be a traitor? Doubtful. Most likely a disguise. But the fact that she passes so well says something, too.
