[SPOILERS S3] was rewatching the show and noticed something really cool
When Noah visits Mikkel in 1986 and talks about god with him. Mikkel is at first skeptical, saying his dad views it as a tool to brainwash people. But later, he's seen examining the picture Noah has tattooed on his back. Fast forward to 2019, he willingly hangs himself, saying, "God doesn't err; he has a plan, for each of us"
So is it possible that Adam sent Noah to 1986 to begin Mikkels' faith? Thus ensuring he would hang himself and that everything would go as it did on that fateful day on the 20th of June 2019? Why would Noah even bother visiting Mikkel unless there was some kind of purpose?
