Once again, interesting. Looking forward to seeing what you'll do with the dynamics of the characters introduced so far. And I can't really imagine where this is gonna go. Obviously, Morty won't be having any luck with his objective, because To Defy Doom, but then one's gotta wonder what this story'll shape up to be about. If Mortimer actually reaches Milt. he'll most likely be trapped there as well, but will he even get that far? There's always the obstacle of the blockade and there's a doubt in me about whether you'll be making this a story with a pattern similar to TRH. Plus, you did mention Morty/Doc. Overbuild dynamics before, so that would suggest staying within the bounds of the NF. But I guess we'll see.
Oh and that janitor scene you'd shown me. You know, I checked the timeline and at least chronologically speaking that could be one of the Janitors. In fact, while the whereabouts of the Original Janitor might be mysterious at this point, I believe the Succeeding Janitor is confirmed to be in the KOTOS dimension in that time. Could be. Don't know if it actually is though.
