if Chester is Jon, then what crack is he on??
Why did he lead Sam to the Magnus Institute knowing that the Archivist was there? The first time could have been a warning but every time Sam says he'll quit investigating, Jon brings it up again. That's not a warning anymore. WHAT WAS HE ON WITH THAT?
And WTF is Martin doing in there?
All of Jon's cases tie into the overarching plot and we know he can send emails. Jonah's are all cases pointing to his identity or themes of ambition and he too can send emails. Martin's cases seem really random. He gave us an Adam case, and a case referencing Celia but other than that he has not been on his A game. Angry building, murdered wife, brutalitist building are all some examples I can think of. He has also not sent a single email.
STEP UP UR GAME BOYS, JONAH HAS ALREADY STARTED MANIPULATING GWEN!!!
