Tried to post this earlier but my internet was being dumb.
My guess is that Libk is a disguiser or similar role- or power-stealing role.
I don't think we got rid of the serial killer.
Please tell me if I'm being crazy.
I agree with this, and think that Deku is right or at least on the right track. So I think we're still dealing with the SK and we have no clue what Ryu's role/alignment was.
I guess I'll say it now that he's flipped, but I thought Zachie might be a scum/third party role. I'm kinda surprised he was town, but I guess town bomb makes sense too. That's why I thought Doc's post guessing he was Zachie was NAI.
Libk makes sense as the SK, and I dunno why I didn't even think about that. But also, people flipping as other people in this game is going to be confusing. Since Libk is still in the game, but he isn't Ryu-Libk (who possibly wasn't even Libk to begin with).
I'll try to post some reads after I re-read d1.
