So here's another thought: All Alen, Fred and Matt are Gs. I'm 100% sure that Matt is a G so he's clearly out tomorrow. But there is nothing to clear @Fred yet. If Alen's the only g who tried to save Matt, his vote would have still only made the vote count 5:5 for x vs Matt, so gs needed another vote to save Matt. Otherwise Alen's vote was gonna be absolutely nonsensical: a hatpick between Matt and x. If Matt is chosen (a g), Alen is in danger. If X is chosen (a c), Alen is in danger. So i believe Fred is probably another g. He may be a c still, but i think chances are more he's also a g alongside with Alen and Matt.

Actually not, your theory is wrong only in that you thought Matt was a c. It cannot be true. Alen wouldn't risk his life by saving a c. But if Matt is a g, as i said above, Fred is actually likely to be another g as well.

Btw, sure c's are the intersection of those who voted Matt yesterday and Alen today: Voller, Radekas, and Woody plus X. If Fred is also a g, we can't necessarily infer that those who voted Alen today are Cs or those who voted Fred are gs.
