Rey spent the entire time helping others. Right from saving BB8 to chasing Finn over a stolen coat. Kicked ass when she calmed herself and channeled the force. Textbook Jedi ideals.

Can't see either switching now.
Just a theory being discussed on the interwebs, personally I don't agree with it either.
