It appeared that Kylo sensed something wrong with him during and after the battle? He maybe did some quick intel on that trooper upon their return?
I don’t get this either. Ren obviously senses something is off with this dude. Wouldn’t someone like Ren immediately place him in custody and have him interrogated?
Didn’t Phasma order Finn to go and get re-evaluated or something? Or, maybe it was just about his blaster? I can’t remember.
