I'm thinking it's also possible that one of the VT claims has consciously decided against claiming Skys role cause they know full well that we're hunting for the guy claiming the janitored role. I don't expect OMB to make a play like that so that leaves Odo and Jeff, and Odos play around Poyser still speaks for itself, so I'm currently thinking I wanna lynch Jeff.
From the other side of things, if there's anyone who's claiming Skys role it's either you (Haza) or Mitch, that much is likely accurate.
