Rey already has training my dudes. Either that or she really is a Mary Sue. You don't just use the Jedi mind trick or summon a lightsaber with the Force on accident. Luke spent the entire Heir to the Jedi novel trying to get that Force summon thing right, and even then was barely able to pull it off in the wampa cave.

Rey - Obiwan's daughter
Luke and Snoke connection.....I'll drop this hint, who was the father of Anakin? or it might be more accurate to say, who has the ability to generate life from using the force ? Was Anakin the first 'chosen one'? or has there been numerous 'chosen ones' in the past?
When Rey has her premonition concerning the Knights of Ren, was Kylo Ren trying to kill her in that scene, or protect her? ....from who? ...another 'chosen one'?
Why does Anakin and Luke seem to struggle with the dark side so much?
When Kylo Ren stops the laser blast in mid flight in episiode 7, I wonder if that is a foreshadow to show how powerful another force user may be? such as, imagine if there was a force-user that had ability to stop 100's, or 1000's of those laser blasts at the same time, that would be an extreme show of power if something like that were to happen.

Unfortunately I've read a few spoilers for ep. 8, and of course who knows if they are true or not, but I have read some interesting possibilities. Including a 'big reveal' ala TESB, but more so a double 'big reveal' that gets you like a 1-2 punch, where you never saw the 2nd punch coming.
Hopefully everything Ive read has been wrong....but I just can't help myself sometimes.
