Another thing that did not make sense is Rey did not even ask how Palpatine survived. If I were Rey, I would ask, "Hey, wait a minute. I have seen you before on the History Channel. You are that evil emperor Palpatine who reportedly died 40 years ago. How did you survive? And why you say I am your grand daughter? What proof do you have? I want a DNA test done between you and me."

She just stand there like "Uh huh, Uh huh. OK Palpatine lived. Good. I am your grand daughter. Confirmed!"
