Supreme Leader Snoke narrates throughout the new Star Wars: The Last Jedi trailer. Snoke's voice is the first voice that the viewer hears as he rasps: "When I found you, I saw raw, untapped power. And beyond that, something truly special." As Snoke speaks, the opening images show Kylo Ren standing alone looking at a First Order fleet, First Order walkers, an aerial shot of First Order troops, and Kylo Ren with his mask and lightsaber. Because of this imagery, it seems as if Snoke is speaking to Kylo Ren.
Additionally, The Force Awakens establishes that Kylo Ren found (or was found by) Snoke, and that Snoke seduced Kylo Ren to the dark side of the Force. It would be a logical conclusion to think that Snoke is talking directly to Kylo Ren in this moment.
However, as the trailer unfolds, who Snoke is talking to becomes increasingly unclear - in fact, it is equally possible that he's talking to the newly "found" Rey.
First, the use of the word "raw" is used twice, which within the short span of the trailer is enough to emphasize its importance. Snoke says that he saw "raw untapped power" in the person that he is speaking to. Luke Skywalker tells Rey that he has seen "this raw strength" that she has before - he's clearly referring to Kylo Ren. In this case, the raw power of Kylo Ren and of Rey is put into direct comparison, making Snoke's comment applicable to either Kylo Ren or Rey.
In the penultimate scene of the trailer, Snoke's face is shown, with his hand outstretched as he says, "Fulfill your destiny." Directly following this close-up is an image of Rey being tortured. She appears to be floating, belly-up with her head hanging back, and screaming from pain. In the background, a figure stands in mustard yellow robes - the same yellow shade as Snoke's yellow costume. This begs the question: is Snoke's opening lines of the trailer spoken to Rey and not Kylo Ren?
In the final moments of the trailer, Rey says, "I need someone to show me my place in all this." Then, Kylo Ren is shown, silently offering an outstretched hand. Kylo's seeming invitation to Rey may or may not be at the request of Snoke, and it's conceivable that Snoke's narration could be him talking to one or both of them. But this ambiguity is made possible by the fact that Rey and Kylo Ren (and their fates) seem interlinked: Rey has the potential to fall like Kylo Ren did, or she could have the potential to save him.
However, the film will almost certainly resolve the trailer's ambiguity. Is it possible to have two characters that are both "truly special?" Given the events in The Force Awakens, it seems more likely that Rey is "truly special" in a way that Kylo Ren isn't... which could create a tension that will drive him further to the dark side.
For now, fans aren't sure of Rey's place in Star Wars either, and we'll have to wait and see when The Last Jedi premieres in December.
