Yeah, k-59 is definitely the best option, for reasons both Aedan, Jackson, and Marshall have all pointed out.
Vote k-59
That said, let's take a look at the others.
Jackson - His first 2 days were not stellar - voted wagon, then spock. Also, he did spend a bit of time attacking wagon early. But he did vote for Griffin yesterday, and his analysis yesterday and today has been reasonably solid. Not out of the realm of possibility that he's a wolf, but not a great lynch target, either.
Wagon - I should probably refrain from comment about his analysis and judgment skills this game, aside from noting that they exhibit all the quality of low-grade dog food. Voted Audren day 1, spock day 2, and griffin day 3 on tie day. If we lynch k-59 and he flips villager, we might want to take another look at wagon, but probably a villager, albeit it a surpassingly unhelpful one.
Teep - Voted Griffin 2 days in a row, and both times Griffin was in danger. Don't know his playstyle, so don't know if he'd be willing to sacrifice a wolf or not to make himself look good, but certainly not a good lynch target.
Ironhide - Voting record is putrid - wagon, jerman, de chatillon, and analysis has been generally unhelpful/based solely off of other people's analysis. However, he did his whole lynch "if you want to lynch a certain villager, lynch me" shtick. I'm leaning towards clueless villager here.
Daffius/Marshall - Sound analysis from both Daffius and Marshall, pointed out the issues in Wagon's play succinctly and well. That said, his voting record has been awful: Audren, Spock, De Chatillon. Worth keeping an eye on.
Rovsea/EUROO7 - Seems disengaged from the game. Not sure whether EURO is busy or just trolling us. Either way, hasn't been helpful to the village and has voted Wagon and Marshall.
Aedan - Made a case on Jerman, then voted spock day 2, so negatives on that front. Votes k-59 yesterday and today, giving solid reasoning both days, and k-59's recent voting pattern seems to confirm his theory. Even assuming he's right and k-59 is a wolf, though, problem is that aedan has been known to sacrifice packmates he thinks are expendable. Keeping an eye on him.
