I think I've got something useful. And of course Didds is disappearing for a day.
If the information provided to us about the fortress is accurate (protection only works if no scum in fortress, protection is against scum, fortress was attacked last night but no one died), then Bright, Didds, and Galz are all non-scum (i.e. either town or 3rd party).
I think this also makes Swowl scum, as he said he targeted Bright with sword from Galz (who under this assumption is not scum). The only way Swowl is not scum is if fortress protection is against all kills instead of just scum kills, or if Doc Didds actually protected Bright, not Awaclus as he claimed (I don't see town-Didds lying like this, but possibly 3rd party).
Alternatively, if the fortress protection has been misrepresented to us, this basically makes Didds and Bright both scum (or at least non-helpful 3rd party), and it makes Galz a lazy/absent town (for not noticing and/or correcting for us here), or else scum-buddy with them or non-helpful 3rd party. It is possible Bright's ability, growing fortress, is 3rd party and they are all 3rd party of some sort now.
But I think it's more likely they are all scum. Thinking of a logical way to give scum-Bright his ability from a design perspective, he has to invite non-scum first. But scum probably only had night QT, and fortress has night and day, so he wants scum in there. pubby wanted faust (or was its fang, I forget) to join, but Bright didn't. So come to game thread and convince us pubby is scum, invite his scum-buddies, vote pubby out (with Didds making sure me and Swowl help), and now he has freedom to day chat with his scum-buddies. Why else has the 4th spot in the fortress (vacated by pubby) not yet been filled?
So we either have 3 non-scum in the fortress, or we have 3 scum in there (and the "protection" from fortress is Didds knowing who to doctor since Swowl would likely tell in Snow White QT who he's targeting with sword scum-Galz gave him). I'm trying to come up with a way to figure out which.
If we assume they are non-scum, then we likely have 2 or 3 scum out of 5 to find (for me, it's out of 4 since I'm one of the five), the first of which is almost definitely Swowl. And we should exile Swowl, especially since he presumably still has an extra kill from the sword.
On the other hand, if fortress is all scum, then exiling Swowl is not a good idea. Absent of RB or doctor (from scum-Didds), that puts us at 3-3 tomorrow after scum kill overnight and no Swowl with Vig sword anymore. So instead we have to exile within the fortress today. No exile gets us nowhere except Lylo tomorrow, unless we have RB or investigative roles available. If we can RB Didds, then Swowl should be able to kill one of them tonight (assuming he still has Galz' sword), and we are at 4-2 tomorrow, but we have a flip confirming fortress member is scum.
Now what if instead, it's Swowl and 1 or 2 others (among fang, Awaclus, and pasta)? Then if we do the plan above, no-exile, and RB our town doctor (Didds), then we need Galz to confirm whether Swowl stil has sword. If he does, then scum gets 2 kills, with our RB tying up our Doctor. If 3 scum, that leaves us with 3-3 tomorrow, the ability to RB Swowl, but we'd need a lucky doctor overnight. If only 2 scum, then I think it's okay to do this.
Over all those possibilities, if we have a RB, I think they need to claim, we no-exile, block Didds, and hope that if fortress is town and Swowl is scum, that there are only 2 scum total (and if fortress is scum, and Swowl still has sword, then he kills any one of them for us). That leaves decent odds, I believe.
If we have no RB claim in the next 24 hours or so, then we probably just need to decide whether we exile Swowl or someone within the fortress... probably someone other than Didds, because we would want Didds to try and protect against scum kill and/or sword kill if Swowl is the scum.
TLDR: if we have town RB, they claim, we no exile and RB Didds.
If we don't, we choose between killing Swowl, or someone in fortress other than Didds.
PPE 4, I think it said. Going to go read them now
