Reread on Chairs, as I'm assuming that he knew who his scum-mates were from the start of the game (as most Traitors are designed this way):
First post (#55) - votes for Morgrim, raw vote, no reason. Could be a loose signal.
vote: morgrim
Next few posts are mostly about a potential for Bart to exist, and don't really involve anybody directly still in the game.
Post #133 is a bit odd, but I'm not sure if it's made more with EFHW as a scum partner, or with EFHW as town:
Ok I think we can safely conclude that the scumteam is e / EFHW / ashersky.
dayvig: EFHW
I want this to be real
In #229, votes WCD (town, from his perspective). In #288, votes Silver (town).
In #318, he gives a short "reads" list, that consists of town on me, town on EFHW, and scum on Ash. This definitely gives scum points to EFHW, as I would expect one scum partner to be in his town reads list:
Sorry, my weekends are really bad for September. I’m not sure as I have much to say, though - I was intrigued by e’s claim that e had already townread iguana and was faking a scum read for the interactions - that annoys me a little as I tend to trust in upfront Town play mostly, but I can’t be too mad because 1) it does sound like town!e, and 2) I have definitely mislead as Town before, to the benefit of my team. I would vote for silver what with the don’t you trust me line which is super scummy sounding to me, but I’m already doing that! I’m feeling Town on galz, Town on efhw, scum on ash, scum on as, kind of neutral on everyone else. I wish galz had put down his vote but this does fit what I remember of him as Town hence the Town read
In #320, he could be telegraphing something to scum teammates Hydrad/Morgrim - either a suggestion that they go with a Mason fakeclaim, or an acknowledgement that he noted Morgrim's claim of Det. Zimmerfield and was on board with where that would lead down the line:
I could be a mason with ash and still find him scum some days lol
In #342 he notes that he likes my case on Hydrad, and in #347 he votes Hydrad. This is on 9.17 at 2:43 FT. This is approximately 17 hours to deadline, and represents vote 2 of 8 needed to lynch. e! quickly follows to put Hydrad at 3. While the time to deadline isn't super long, 17 hours is honestly enough time for everybody to log on and participate at least once more before deadline. A lot could happen in that time. I'm not so certain that Chairs, even with vote #2, decides to cast his vote on one of his two partners at this juncture. It just doesn't seem like a good move when he was himself the second wagon (at 4) and he was moving FROM the leading wagon (town-Silver) who was at 5 votes.
Like, this move alone makes me want to completely write off any chance of Hydrad (and by association Morgrim) as being scum.
That said, he doesn't stay there long, and in #387 he jumps quickly to the Awaclus wagon, where he stays until the end of D1.
D2 he opens in the exact same way he did D1:
vote: morgrim
If you're a believer in the Morgrim/Hydrad/Chairs scum team, this definitely looks like, twice, he tried to signal to them.
His next meaningful contribution (there are posts throughout D2, but they almost all relate to being too busy, or are about the vote that he was controlling [Note to self: Reread who Chairs moved votes to]) comes in #653, when he votes for Hydrad... without really much explanation as to why:
I really want to contribute here but this is my week where I get to spend time with the girlfriend I’ll try to find a little time tonight. In the meantime vote: hydrad
... and that's it for D2. So his entire D2 consisted of voting for Morgrim, and then Hydrad.
On D3, he opens early with a "test" vote on EFHW (#844) - although he would know full well that his vote would count and who's vote he controlled at this time. Following this, he turns his first actual post of D3 into an endorsement of Hydrad/Morgrim:
I, for one, firmly believe the Mason claim.
This is interesting... Chairs is either trying to steer all potential reads/lynches away from his partners (Hydrad/Morgrim), or he names at least one of his partners as scum in his dream:
I honestly had a dream that this game was over already. Oops.
Who were the scum?
I’m a bit fuzzy on details but I wanna say it was Space and Galz as mafia and then you were the SK
And that's all for Chairs.
------------------------------
So, reading this, if it weren't for the late D1 switch off of town!Silver (leading wagon) to Hydrad when Chairs himself was the second leading wagon, I would definitely think that the votes for Morgrim/Hydrad D1 & D2 were signals to partners. Like, that's pretty decent evidence. But... I honestly just don't think Traitor!Chairs (at 4 votes) moves from town!Silver (at 5 votes) to Mafia!Hydrad with 17 hours to deadline.
There are a couple of things that suggest that EFHW could be a Chairs partner though, and then Chairs never once mentioned Datswan in any fashion whatsoever.
