Randakar (548)
THE_SPLIT (561)
Health (582)

Yvanoff (623)
Claude LC (624)
cliges (629)
k-59 (616 Sleepy -> 631)
Castor94 (640)
I would guess that there is one more "Yay" wolf in this list that voted with Yvanoff. Here are some comments on each player's voting history.
Randakar: voted with Yvanoff against Health on Day 2 (although I would find it hard to believe that two wolves did something this obvious), voted TheFatWombat on Day 3 (was voted by Eternity_Lost - these two don't give us much information as of yet), was the first to vote for Black_Griffin on Day 4. No real good evidence here (unless you think that Yvanoff would vote with Randy on a player who wasn't a lynching candidate).
THE_SPLIT: voted Reis91 on Day 2, Jeray200 on Day 3 (didn't switch to Avernite), 2nd to vote B_G on Day 4. Hasn't been voted up yet. No good evidence here because we don't have anything on the players he voted for beside B_G.
Health: voted BlackCrown voted by Alynkio, randy, and Yvanoff on Day 2 (along with k-59 and cliges, who area also on this list), voted Aedan 2.0 on Day 3 (the EURO, johho, alynkio trio that Reis91 mentioned yesterday also voted for Aedan 2.0), voted B_G on Day 4 (was voted by johho and spockyt). The Yvanoff vote on Health on Day 2 could be an alibi vote, but we cannot be sure.
beartjah: hdk and beartjah voted for each other on Day 2, voted JermanTK on Day 3 before the switch. Voted B_G on Day 4. Hasn't been voted since Day 2. He has been lynching the nay wolves almost too well.
Claude LC: voted Brovahkiin on Day 2, no vote on Day 3, B_G on Day 4. On Day 4, he was voted by a few people because of his no vote status on Day 3. Seems a little fishy (his no vote status, not people voting for him).
cliges: voted BlackCrown on Day 2, JermanTK on Day 3 before the switch. Voted B_G on Day 4. Like bearjah, appears to have a too good to be true record. I also didn't see any votes on him, although I could have missed them.
k-59: voted Jerman than BlackCorwn on Day 2 (was voted by Lemeard), stayed on Wagonlitz on Day 3 despite the (fake-ish) outing, switched from Sleepy to B_G on Day 4.
Castor94: voted Brovahkiin on Day 2, JermanTK on Day 3, and sniped B_G to save himself. Like beartjah and cliges, his voting record is filled with red. Also, the vote snipe would have looked fishy had JermanTK not turned out to be a wolf.
I'm going to have to contemplate on these choices for a little bit before I vote. I am tempted to vote Health because of the Day 2 vote by Yvanoff, but the Euro/johho/alynkio trio on Aedan 2.0 on Day 3 makes things complicated. Although I feel there is a wolf or two among those who voted for Aedan 2.0 on Day 3 because Aedan 2.0 was the only non-nay-pack candidate that day and a prime target to get some pressure off of their pack mates, I'm looking for someone from the yay pack. Although it is not out of the realm of possibility that a yay pack member also voted for Aedan 2.0, it is more likely that if there are wolves there, they are part of the nay pack.
