This show redeemed itself with S4 and then immediately crashed afterwards...

Christians can get esoteric, too. There's no conflict there. And TM is a particular form of meditation that comes from Maharishi Mahesh Yogi's movement.

Also, his so-called dark passenger is still fucking there. He's eventually going to start killing lumberjacks and we'll be right back at square one.

What if, because eventually people are going to figure out the big twist, you double cross them and it turns out they really are two different people.

Then a lot of assumptions people made about character motivations go completely out the window and they have to re-evaluate everything they thought they knew. Make sure their actions are still internally consistent though.

Anyway, just spitballing.

They are two different persons with just identical lives.
