Okay, I figured it out. Gamma is either going to be painted into a corner tomorrow or not, which means we don't actually have to eliminate within unwnd/Gamma or do No Elimination today. The nightkill is also going to give us independent confirmation of whatever Gamma says--basically, if Gamma is telling the truth, scum
needs
to kill him to avoid getting two confirmed townies or one caught scum. That's either a dead duck (probably) or a dead Gamma tomorrow, if TW is doing some wacky scum gambit (unlikely).
That means if we eliminate within unwnd/Gamma or do No Elimination today, we get the same information tomorrow as if we continued looking for scum elsewhere. The advantage is having a better chance of eliminating scum, but if we pick wrong, we're one sorting-and-eliminating attempt behind compared to voting outside of unwnd/Gamma/No Elim.
I think this makes sense even if you don't have my green role PM; you just put me into some of the possible PoE slots and the logic still works.
