"I've seen your eyes. I know your eyes."
This is the TV spot that spoiled the central mystery of the movie.
I disagree...the voice could be talking to Leia or somebody else....just because Rey is the main character shown in the trailer doesn't mean the voiceover is directed at her.
The clip from the previous trailer, where the saber is handed over....from what people are saying, that’s Maz Kanata who hands the saber over....it looks like its Leia who’s accepting it...if so, the narrative could be directed at her as Maz Kanata notices the similarities between her and Luke.
Remember how clever the voice over was used with Palpatine talking to Vader on the Revenge of the Sith trailer? That was taken totally out of context when you saw the full movie.
