On a non in-story note, it would be SMART to have him become a Jedi. I've been seeing slot of posts bashing the movie for being unoriginal, but a solid majority seem to think nepotism is the only way the force "which flows through all things" is the only way the "super power" can be obtained, and makes sense. Forgetting the the Jedi were in large and part an entire religion spanning an entire galaxy.
The notion that ONLY a Skywalker should be able to do this is what I find funny.
On an in-story note, misdirection aside, Kylo-Ren and Finn had some interesting Stare downs.
1. At the village. He stopped dead in his tracks to look at the Storm trooper. He then says nothing to the trooper's commander about the insubordination. Just takes a mental note. Hmmmm.
2.the first meeting we have with Smoke he mentions the awakening that he and Ren have felt. This is almost immediately after the village incident. Before we meet Rey, and before She knows anything about the force.
3. When Poe escapes with the aid of some inside help, Ren already knows which one. By number. Again, after the evil pep talk, but before Rey.
4. They exchange intense looks when they are both out of helmet. How does Ren KNOW that the person he's looking at is FN 2187?
5. Finn tossing the training droid while looking for first aid stuff.
6.Maz seems to know of more about his situation. That crawl across the table didn't have be do e for emotional effect. That's fore shadowing.
I copied and pasted this from some forum but it makes sense
