I don't feel like testing JeenLeen or The Outsider again. At least today, that feels like a mistake.

I'm reasonably certain that Apogee1, Elenna, PartyOfRouges, and Valmark aren't the original Thing. That leaves Book Wombat, CaoimhinTheCape, and Grek, who I will vote for tomorrow assuming that neither of these two flips Thing.
