You're not the real Hivemind, are you?
Agreed. Tiruin's actions on day 2 make no sense if she's actually the Hivemind - I'm pretty sure she was town at that point and was converted night 2. What she's doing now is presumably to try and make sure no shots are taken at the actual leader. This is why I said the actual Hivemind is super hard to lynch - his followers can just jester themselves every day and they still get further ahead.
I still think it's
TheDarkerStar. His claim smelt of bullshit from the start (Assassin Bot is a bad pick for Agent Operative, he claimed his investigation result but ummed and ahhed about whether to make his convert join in on the claim) and covers an actual Hivemind role perfectly. I can't completely rule out him being the night one convert and hector13 being the actual Hivemind instead, but I don't think a Hivemind would claim kook.
Also I think doll may have been (foolishly) helping the Hivemind team on the understanding that he would be converted later. He stated multiple times in the thread that he would be happy to do that. Honestly cults kindof screw up the "townies don't lie" dynamic of a normal game because townies can actually act as if they're scum if they think that's the alignment they'll end up with.
It's possible the Hivemind whiffed on getting a conversion at some point due to hitting a non-human, so it's worth trying to lynch them. If they actually did get a third convert we can at least discover who the whole team is like webadict said.
