I bet there's scum on the Grujah wagon, I don't think scum can let half the town be cleared right after day 1. Especially when there's a town this big, we've got to have a whole bunch of them. Still, I would expect that there's more scum off the wagon than on it, so we should start by scumhunting there and then find the bussing mafia later.
Nightkills - mafia would kill someone from the wagon. Of the people who died, eevee and glooble were on the grujah wagon, O was not. I'd guess mafia kill either eevee or glooble; if O was targeted then that was probably a vig kill. So we probably have either two scumteams (well, maybe just mafia+sk) and no vig, or just mafia and vig. With this many potential targets, I would really doubt that we had kill-collision, so I think there's only 2 nightkills going around.
Weirdness with Eevee dying due to some interaction with the cult is also possible, I'd sort of assumed the recruiting faction doesn't get a nightkill.
Maybe the card is either Glooble or O's card, and the other one of them was Copper? That would fit, copper/coppersmith as lovers.
Looking back to D1 - out of the people who are still alive:
Were on the grujah wagon at the end: ehunt, yuma, watno, Galzria, eHalcyon, Cuzz, Morgrim7, ftl, jotheonah, Axxle
D1, grujah voted for: cayvie, yuma.
Had earlier voted for grujah but unvoted before the lynch: Dsell. ...and that's it, actually.
People who didn't have any voting interaction with Grujah: (Voltgloss)/sparky5856, Insomniac, Young Nick, Voltaire, Shraeye, igbtennis, TheMunch, Captain_Frisk, ashersky
I think the last two groups there should be our most likely suspects. So Dsell, volt/sparky, insom, YN, Voltaire, shraeye, igb, Munch, C_F, ash.
Ima go back and see whether any of these people seemed wagon-happy until the wagon got to Grujah.
