But like you said, it's multi cannon, and I get that you read Juice as town. They claimed they needed 2 night for their role to work, or something like that. My paranoid mind takes me to killing role, cult-ish role, or the role that can switch, something Juice accused me of softing.
So I understand why you think that way about the wagon, but I also doubt that they tried to vote there to try to counter Lethal, it was too early in the wagon, and that is why I don't agree with the method of your reads to some extent.
You could
a) be correct and Juice is just town and they are mafia.
b) tying to push a narrative that helps Juice's slot, achieve their goal of being alive for 3 days.
c) You are wrong and you are trying to push Grim, other players confirmed to me that bussing was usual here.
So, I won't go after you atm, but I will not ignore that your reasoning is a little weak from my POV.
