Well suddenly it makes way more sense. I wish the movie had some of that in though to explain, especially the relation between leia, the republic and the first order.
How did the first order managed to build Starkiller tho ? If they barely have funds for ships, but turning a planet into a base with a superweapon is all good ?
And, once Starkiller gets turned into a star itself, that action basically nukes the majority of the First Order, doesn't it? Episode VIII should end up being the same situation in reverse - a small band of FO troops with Ren hunting down Skywalker, and the Resistance having the upper hand in terms of troops and ships.
The only way that's an even fight is if Snoke and Ren have something up their sleeves, which makes me way more interested in where Episode VIII could go.
I think it's pretty clear that JJ Abrams wanted her to be Luke's daughter. Especially with how much import is placed on her family and her connection to the Skywalker lightsaber. Whether Rian Johnson goes with this is up in the air, but I think he will.
I keep seeing people say this, or perhaps lineage to Kenobi, but wouldn't that entail that Luke or Ben had a wife? And wouldn't that be in violation of the "Jedi Way"? Immaculate Conception theories aside, I find Rey being a descendant of Luke or Obi-Wan unlikely for this reason alone.
