Get ready for a long post!
Let's take a look at the remaining player's voting record and see what pops up. I am ignoring days 1 and 2 because of the no-hunt on Night 2, which makes me believe our last wolf used to be a villager, but was cursed.
Key: Day X - votes (number of votes on votee), voters for this player [vote count leaders for the day]
Randakar:
Day 3 - 1st vote on Arkasas (2) [Grimlock/Caillean 5/5 -> HistoryDude 5]
Day 4 - 2nd vote on Aedan (2) [Grimlock/Jacksonian 5/5]
Day 5 (pre-outting)- 3rd vote on Aedan (3) [the_hdk/Aedan/Caillean 3/3/3]
Day 6 - 2nd vote on Arkasas (1) -> 1st vote on Sleepyhead (4) [Sleepyhead 4]
Ironhide G1:
Day 3 - 4th vote on Caillean (4) [Grimlock/Caillean 5/5 -> HistoryDude 5]
Day 4 - 4th vote on Jacksonian (5) [Grimlock/Jacksonian 5/5]
Day 5 (pre-outting) - no vote [the_hdk/Aedan/Caillean 3/3/3]
Day 6 - 1st vote on liefwarrior (3) [Sleepyhead 4]
Arkasas:
Day 3 - 4th vote on Grimlock (2) -> 5th voter on HistoryDude (5) [Grimlock/Caillean 5/5 -> HistoryDude 5]
Day 4 -4th vote on Grimlock (5) [Grimlock/Jacksonian 5/5]
Day 5 (pre-outting) - no vote [the_hdk/Aedan/Caillean 3/3/3]
Day 6 - 3rd vote on liefwarrior (3), voted by Sleepyhead, Randy, and Dedonus [Sleepyhead 4]
Caillean:
Day 3 - 1st vote on Witch Agatha (2), voted by Wagonlitz 2.0 [Grimlock/Caillean 5/5 -> HistoryDude 5]
Day 4 - 5th vote on Jacksonian (5) [Grimlock/Jacksonian 5/5]
Day 5 (pre-outting) - no vote, voted by sleepyhead, aedan, and the_hdk [the_hdk/Aedan/Caillean 3/3/3]
Day 6 - no vote
The first thing that stands out to me is Day 5 for Caillean. She was voted by 3 baddies ( sleepyhead, aedan, and the_hdk) and she was in a three-way tie with two baddies (aedan, and the_hdk), prior to Aedan being ousted as a cultist. This allow makes me believe she is not a wolf. Also, because sleepyhead turned out to be a cultist, the last remaining wolf had to set the hunt order. Unless the MAWofdoom hunt was a standing order, Caillean could not have set the vote because she wasn't present on Day 6. The only counter to this argument is that Caillean was logged in, but didn't post in the game thread (an action that should be frowned upon).
Randakar has voted for baddies on three day (Aedan on Days 4 and 5, and Sleepyhead on Day 6). At first glance, this seems like an excellent vote record.
Ironhide has a terrible vote record, never once voting for a baddie. The only saving grace is that, except for yesterday, most days have either 2 villagers or 2 baddies run up (or a baddie was switched). So it is hard to say Ironhide was trying to save a wolf.
Arkasas best Day was Day 3, where he joined the switch on HistoryDude. He was also voted by Sleepyhead.
From the above analysis, one might say we should go after Ironhide G1. However, I would like to look at these four days under the assumption that caillean is a villager.
Day 3:
Before the switch to HistoryDude happened, two villagers (Grimlock and Caillean) were the frontrunners and no wolves were in danger of the lynch. Two baddies (the_hdk and sleepyhead) voted Grimlock, while two baddies (Aedan and HistoryDude) placed throwaway votes on Capage and MAWofdoom, respectively. Arkasas and Ironhide G1 had votes on the frontrunners, while Randy had a vote on the non-frontrunner Arkasas. Of these three votes, Arkasas' seems the least wolfish because there are already two baddies on Grimlock. Ironhide's vote could be seen as helping push two villagers into a tie, while Randy's vote could be a throwaway vote while the village lynch their own. Also note that Arkasas is the only person of these three players who moved their vote during the vote switch to HistoryDude.
Results: Good points to Arkasas and Bad points to Ironhide and Randy
Day 4:
Two villagers (Grimlock and Jacksonian ) were the frontrunners and no baddies were in danger of the lynch (Aedan with 2 votes was the closest). Each frontrunner has a confirmed baddie on them (the_hdk and sleepyhead, respectively). Aedan tried to push me as a candidate (and failed). Both Arkasas and Ironhide had votes on the frontrunners. I could see a wolf could vote in either of these positions, but I am more interested in Randy's vote. He placed a 2nd vote on Aedan when Grimlock had 3 votes, Jacksonian 2 (or 3 if we are counting MAW's alderman trait), and I had 2. With three villagers as the other candidates, placing a vote on Aedan would not be dangerous for a wolf and if Aedan happened to get lynched (he didn't until the next day), Aedan is just a cultist. Therefore, I see Randy's vote on Aedan on this day an alibi vote.
Results: Neutral points to Arkasas and Ironhide and Bad points to Randy.
Day 5:
Two baddies (Aedan and the_hdk) and one villager (Caillean) were the frontrunners before Aedan was ousted as a cultist. Unfortunately, Witch Agatha did the outing a little early and we therefore do not know how Arkasas and Ironhide would have voted without knowing Aedan was a confirmed cultist. Randy pushed Aedan into a tie with the_hdk. On one hand, this could indicate that Randy is a goodie. However, there are arguments that this could have been another alibi vote. There were still ~2 hours left in the day and 4 players who hadn't voted yet. Furthermore, just like I mentioned on Day 4, Aedan is just a cultist and is more disposable than a wolf, like the_hdk. Finally, if Randy had voted Caillean and it was revealed that Aedan and the_hdk were baddies, it would look really bad for Randy to vote with 3 baddies when 2 baddies were the other candidate options.
Because we don't have useful info on Arkasas and Ironhide on this Day, it would be unfair to penalize Randy. However, I will still keep in mind how Randy's vote looks to me in my conclusion.
Results: no points rewarded (another Randy alibi vote?)
Day 6:
One baddie (sleepyhead) and one villager (liefwarrior) were the frontrunners and these were MAW's preferred candidates (and I concurred with them). The only known baddie (sleepyhead) voted for Arkasas. This could be an alibi vote, but for most of the day, liefwarrior was the frontrunner. Randy's vote on Sleepyhead is similar. Could be an alibi vote, could be a dangerous vote that could (and did) lead to Sleepyhead's death. Both Arkasas and Ironhide voted a villager (liefwarrior), but everyone thought liefwarrior was a good candidate. Both villager and wolf could have followed that. However, Arkasas stated he was voting liefwarrior out of self-preservation, but he thought that Sleepyhead felt wolfish. Ironhide thought that lief and sleepy were the most suspicious players.
But what is interesting is Sleepyhead's analysis. He pointed towards arkasas and ironhide as his favorite candidates for the remaining baddies and said that Randy was very unlikely a baddie. To be fair, everyone said that Randy seemed like a villager. But what is more likely: Sleepyhead throwing his last remaining wolf packmate under the bus or putting forward the case that everyone else came to (i.e. Randy's multiple votes on baddies). I am leaning towards the latter.
Results: Neutral points to Arkasas and Ironhide and bad points to Randy.
Conclusion: Through this analysis, I feel Arkasas is least likely to be the last remaining baddie. Ironhide comes second. And Randy, despite voting baddies three times (4 with yakman, but that happened prior to the 2nd no-hunt) looks the worst in context.
