That I believe came from two distinct ideas.
One that if neither of them were mafia then mafia would have killed one of them to have multiple players killed in one night. So hence that neither of them are dead then at least one of them must be mafia. I believe this was originally proposed by cloned (which he is claiming neutral so, that I would say should be taken with a grain of salt),
The second one proposed more so by orange is that in said lovers chat he managed to get numerous confessions out of squirrel. Including ones regarding squirrel’s role and alignment. (What exactly these confessions are will probably be unclear until the game is over)
Overall what I have come to as my conclusions for this day. Is that I would stay on orange (for more so the reasons I mentioned earlier) and see what results from this. If it kills the three of them we deal with that, if not we move on from their and get down to tying to find the truth of this game.
