Ok. I'm going to go through and take a look at each person's interactions and reads on Hydrad.
2.7: #497 Says he's not super excited about the Hydrad lynch--and isn't going to vote him. That's basically all he says about the Hydrad wagon. He makes the case on WW and seems to want to lynch him really bad. In light of Hydrad's flip, I'd say this is fairly scummy behavior.
ADK: #567 Says he really likes voting for Hydrad and tells everyone to vote him. Makes some points about SS switching off the Hydrad wagon. Except...he doesn't vote Hydrad later on and ends up leaving his vote on SS for the rest of the day. I was actually hasty in my earlier post because I thought he was voting Hydrad at the end; he wasn't. If he really had such a scumread on Hydrad, why not hammer?
Ashersky: #519 He says he doesn't like the Hydrad lynch and won't support it. He defends him and deflects from his wagon pretty consistently. I don't really like his "you had me fooled" at the end of the day either--it looks weird. I can easily see Ash as Hydrad's partner.
Awaclus: He votes Hydrad early, says he's scum--and keeps his vote on him until the end. I think it's very, very unlikely for Awaclus to be Hydrad's partner.
Faust: #522 begins his post with saying he "kind of wants to lynch Hydrad" and ends it with continuing to tunnel me.
#614 he votes Hydrad putting him at L-2. And...that's where his vote stays. I think faust is a very unlikely partner for Hydrad.
Joseph2302: He also votes Hydrad about 3 irl days before and leaves his vote there. Another non-partner I would say.
silverspawn: Eh, he does hedge on Hydrad quite a bit. In his #654 He puts him to L-1 though. I think he's townie otherwise, I'm going to give him the benefit of the doubt on this one--as I also felt misgivings about lynching Hydrad. Although him accusing me of being Hydrad's partner does weird me out a bit.
WW: Voted Hydrad early on, never changed his vote. Their interaction after Hydrad claimed scum looks genuine. I'm really not seeing him as a possible partner.
chairs: Hammered Hydrad--he had found him scummy earlier. I'm not seeing him as a partner.
Ichimaru Gin: Hedges on Hydrad a fair amount. There's some interesting interaction with SS warning him off the wagon and accusing him of trying to distract from it. He isn't on the final wagon, he says he thinks Hydrad's scummy a bunch of times and basically tells someone to hammer him. Is this how Ichi treats his partners? I'm thinking not.
I guess my analysis is mostly based on the assumption that Hydrad's partner didn't bus him. I think that's a fair assumption to make though. I've found that scum is normally pretty blatant in defending their partners. As such, I really want to lynch out of ADK/Ashersky/e today. A useful corollary to this would be to go back and look at Hydrad's interactions/reads and compare them to this. I might do that later if someone else doesn't. His major scumreads were myself, SS and XP if I remember correctly. Also, just because I put your name in green doesn't mean I think you're town--just that you're not Hydrad's partner. I actually think Ash is the scummiest after going through all this.
