In the cover at the ends of the trailers, Weiss has a scar, not a beauty mark. It's an edited version of the earliest concept of Weiss. Plus, in the early concept, she was holding a silhouette of Myrtenaster that had a different shape to it than the current Myrtenaster, but in the cover, she's holding the final concept of Myrtenaster.
