"One of his students destroyed it."

So now that Force Awakens is out on home video, I can rewatch till I get sick.

One thing I noticed

In my viewing in theaters I thought Kylo Ren killed a bunch of other Padawans or Apprentices ala Anakin.

This time I listened to Han explain.

Luke had been training a new generation of Jedi

And then one of them (Presumably Kylo) "Destroyed it"

Questions:

How many little Jedi?

How did he destroy it?

What if there were only two?

Ben Solo

And Rey

Origins of Rey aside she is obviously more powerful then Ren. Assuming he's 30 as said (I have my doubts but for theory)

Ren was born one year after Endor

Rey about eleven after.

According to Wikipedia.

Lets say what happened was Kylo Ren, influenced by Snokes, snuck Rey out and dropped her on Jakku. Perhaps jealous of the special attention she got from Luke.

Threatened by her ability, or maybe another Bullshit prophecy. Who knows.

Force Mind Tricks happen. All Kylo would need to do is jumble a young Rey's memory. Again, he has eleven years on her, so easily late teens or twenties.

Follow up: He knows about Rey on Jakku. When one of his followers speaks of BB8 having help from a girl, he reacts not with sexist frustration, nor another hissy fit. But alarm and question: "What girl?"

Thus Luke could have potentially taken off trying to find Rey, because "He felt responsible". But the universe is HUGE. Assuming Ben didn't run off right away.

Next up: Han Solo even thought about going to check Jakku to find the Falcon. But never did. Why?

Potentially a Force Mind Trick. Wouldn't be hard.

The extent he (Ren) fears Rey-he knows who she is. What she can become. What a danger she is. That he knows she is untrained.

Again, this is all conjecture and theory. But its mine.
