Possibly the most talked about part of the trailer was Rey's appearance at the end where she sported some classic Sith clothes and an angry-looking red lightsaber. While some have speculated she's going to turn out to be the Big Bad of all of this, I, on the other hand, don't see Star Wars making the same blunder that Game of Thrones did earlier this year. Most likely, this is Kylo Ren's vision from The Last Jedi that Snoke tried to manipulate him with. It is interesting to note the lightsaber in this scene has the same crackling, unstable energy as Kylo Ren's. Showing this in the trailer also negates really any shot of this being more than some nice pre-movie hype. When The Last Jedi was in its marketing phase, there was a list of what previews and trailers could and absolutely could not show, I imagine it will be the same with Rise of Skywalker. But it still looks pretty awesome.
