Okay, so I read through KoD's ISO, and it really makes me think the next puzzle to solve is Fext/Hapi.
Hapi: I pushed Hapi somewhat, and looking back, KoD did a lot which indirectly defended her, in particular by attacking me for very reasonable things (such as asking to see some past games). This could be a WK situation where KoD is trying to pocket Hapi, but also very well could be a chainsaw defense. When I pushed KoD for thoughts on Hapi, they could not give anything of substance, and their ISO is devoid of any sort of criticality towards Hapi. I think nothing here rules out KoD/Hapi as a team, and in fact the ISO probably is slightly indicative of that team.
Fext: Now this is an interesting one. First off, for the lack of engagement that Fext had in the thread, their name does pop up quite a bit. KoD seems mildly critical of Fext the entire time, but interestingly, seems to never mention Fext alone, and always ties Fext to someone else (usually Alana, sometimes me). In particular, KoD often shades Fext, but always seems to focus more on Alana, and always wants Alana first. When I am scum, I sometimes specifically try to tie my scummates to a townie or two, in hopes that either 1. the townie goes over first, which actually helps clear my scummate because of worldbreaking, or 2. if in the worse case my scummate goes over, that townie is now a target. The insistance of always mentioning Fext with Alana, along with pushing Alana first really fits this, so again I think Fext is compatible with KoD, and the ISO does not look good for Fext.
Based off this, and generally how I'm feeling about others, it seems very likely that at least one of these two are scum. But now... the dilemma!
Fext vs Hapi: There seems to be quite a bit of tension brewing between these two, which would suggest not teamed. However, I'd like to posit a tinfoil theory that actually they could be. Fext's push on Hapi was not exactly great, and with Mongoose/Alana wagons relatively well-formed by then, Fext's push for Hapi near EoD1 I don't think put her in that much danger, and Hapi voting Fext there was just weird, and honestly doesn't jive with the idea that Hapi was townreading Alana at that point, since that actually could have gotten Alana killed. I wonder how much would have been made of Fext vs Hapi if I did not engage with Hapi about Fext's comment. Would they have continued to fight, or would that have been the end of it? It is possible that i pushed Hapi into committing to a stronger scumread of Fext than she really intended? Also, if Fext was really concerned about Hapi, I have a hard time thinking that Fext wouldn't be looking into their posts, but Fext seems to be doing everything in his power to avoid actually forming an informed read of Hapi. So, while I don't want to say this world is super likely, I think a Fext/Hapi world is not impossible.
It is very possible (honestly, likely if you ask me to take off my tinfoil hat for a second) that only one of Fext/Hapi are scum, and I think if I had to decide an elim right this second, it would definitely be Fext. If one of them does flip scum though, I don't think I'd rule the other out, even though it probably would be a point in their favor.
