I had NO idea Cypher was original big bad. Interesting. The Cypher and Warlock arm and the M/Penance meta morph were two things I found exciting that were never explained. I'm very curious where Doug has been and given his recent scolding of Rasputin it seems perhaps he may still be traitor X inside the Secret QC. But we also have literally NO information.
I would love to hear any of Hickman ending ideas (credible). Please pass along.
