Old show new theory

Big fan here. Seen the show too many times to remember and on this last rewatch I noticed something that had somehow escaped my notice, and it kinda blew my mind. Walter Jr. (Flynn) and Jesse Bruce Pinkman (Captain Cook) are never seen in the same room at the same time over the course of 5 long seasons. The truth hit me like a ton of bricks; Jesse and Flynn are the same person.
