hey!! guys!! are you all ready for the foece to be awakened but before that what Im abou to tell you is that this is just theories based on the trailers that was release.
In the second trailer we see an fallen star destroyer and x-wing and hearing the voice luke skywalker(mark hamill) saying "the force is strong in my family, My father has it, I have it, My sister has it, and you have that power to" and battle rages on and on then siddenly han solo(harrison ford) and chebacca(peter mayhew) appeared and han solo said " chewy were home" and the end trailer 2.
Now the third trailer we hear rey and I believe she's talking to leia(carrie fisher) asking rey "who are you?" "I'm no one" rey replied then the trailer continued rey talking to bb-8 asking him "where do you come from?"I'm all about waiting... for my family" and then she's with finn while bb-8 is telling them the empire is coming burning the place down.And kylo ren talking "I will fulfill our destiny, I finnish... what you started" both of them running away from the emphire, the millenium falcon flying away from two tie fighters,finn and rey introduced themselves to each other, and x-wings started to appear, storm troopers appearing< and rey talking to han saying "those stories about what happend" and han solo said " the force is true all of it" and after a few scenes she said "hope is not lose it is found" and thats that i hope you guys loved my article about the trailers of "star war the force awakens".
