Holy shit!
Laura was right! I remembered like ten episodes eight posts later. The title.
I had assumed it was totally lost and stopped trying to remember, and also that it wasn't as good as I remembered. It's maybe not the holy grail of clever titles, but it works. And I'm writing it down here before I forget again.
I could totally and accurately call the impossible-to-write impossibler-to-sell-or-get-produced pipedream project with the near-future sci-fi elements Uncanny Valley. (Or The Uncanny Valley?) It really is a good (though maybe not "perfect") title for that project, and would in fact legitimately help me craft the themes of the show by having a sort of "anchor" concept, even as abstract as that.
Good job, brain. Way to come through in a pinch.
Kind of makes me want to write it, actually. As predicted.
