Over two months after the series finale, the showrunner of Traveler, David DiGilio, has posted a blog that explains "what would have happened" if the show hadn't been cancelled.

It's very long, so I haven't had time to read it yet, but I will. I just wanted to let anyone who was still curious know that there's been some kind of closure.

I read it a while ago, but forgot to post my thoughts. And it wasn't that long once I got into it. I don't understand why the Fourth Branch would want to destroy the painting itself when obviously people would have copies and know of its existence already. That doesn't make sense. Otherwise, sounds good, I guess. I would have wanted Marlow to kill Chambers instead of the other way around, but whatever. Nice to be able to read what was planned, though.
