No way in hell Macalister is red john. No way macalister after janes "breakdown" could offer him a new life. What could the sheriff offer him? He isnt styles or frye hes just a guy with power. Red john wants to turn patrick. He wants him as a "disciple" as jane says . Brett styles is alive . He is red john. Van pelt is his daughter . Jane knows all of this too. Its a long chess match.
