Still trying to get my head around it! If they're filming reveal after reveal, what if a traitor incriminates themselves during a decoy reveal? Splice it into the real one? And, if everyone is faking surprise again and again, how can the faithful possibly catch those who are really pretending?

Wow. That would explain why the faithful never use the info! While filming all these takes with different groups, do they manage to keep from the faithful who has been murdered till the end? Are the reactions we see (and reactions to reactions) raw and original, in other words?

So here's an alternative. The N surviving players from the traitors' murder shortlist are distributed, one in each of the last N groups to arrive. The viewers get a suspenseful countdown to the reveal and the faithful have no unfair access to info. Everyone's happy 🗡️ 3/3

Apparently the show gets around this by filming multiple "last" entrances to breakfast, with the players unaware which is the real one for broadcast. For the sake of some storytelling, this must massively break immersion for the players, particularly as reaction to murders is legit info 2/3
