Now, tying back into the main plot line. This is a few years after Ben joins the First Order. We start out with Finn, who is currently on a raid in the name of the First Order when he sees one of comrades shoot an innocent civilian for "being in their way" and he just thinks "That's not right." Eventually, the New Republic arrives and a shoot out happens, and Finn gets left behind and taken as a hostage. He's met with some questioning and he tells them, well, almost all he knows since he was literally raised in the First Order mindset (he was around 5-6 when his parents joined and indoctrinated him.) Of course, the New Republic finds this troubling.
Finn basically stays as a prisoner until Poe Dameron gets him out and claims he needs Finn for a mission against the First Order. Finn is still very hesitant, since, again, he was indoctrinated with this mindset.
While the two are doing this, newly knighted Rey is at the temple meditating, when she gets a disturbance in the Force and gets FUCKING DECKED by a vision of red blades, blaster fires, and a strange masked man. She is instantly troubled by this and seeks out Master Skywalker for help. He is concerned and tells her to see Grand Master Tano (wink wink)
Yes, Ahsoka is Grand Master bc (to my knowledge) she is one of the few living Jedi that survived the Purge and remember the old ways of the Jedi, and Luke deemed it fit, since she is also the eldest at around 70, and Togruatas can apparently live up to 200 years.
Rey meets with Master Tano, who is very understanding. I'm unsure if what EXACTLY the advice is the Master Tano will give her, but it seems to help Rey a bit.
