From day one, it's obvious that the Witnesses must endure the Seven Tribulations. So far, they only encountered two of them: Moloch, and Pandora and the Hidden One. But it's been very confusing with Season 4. I believe the next one was Dreyfuss since he raised all 4 Horsemen til Ichabod used the Philosopher's Stone. And with the series cancelled, how many do they really have left? What were the former tribulations based on? What should happen to Ichabod and Lara in the future?

It left me with many unanswered questions. And some unease ontop of it. Could someone please clarify all this? Any ideas?
