One thing though regarding mechanical speculation:
Jingle is renowned for being really good at balancing games, so I expect this game to be impeccably balanced.
I went over the last ~8 Large Normal 17ers, and in all of them town had between 4 and 6 PR points (where a full cop is 2 PR points, a full JK is 1 PR point, and a 1-shot roleblocker is 0.5 PR points), with the average being (surprisingly) 5 PR points. Also scum had on average 2.5 PRs (but they are often pretty weak ones, like various 1-shots), so having two mafia goons with 5 PR points is definitely not out of the question.
In this setup we have:
Rolecop - 1 PR point
Babysitter Hider - 1 PR point
And the following claims:
2x Miller - 0 PR points
Odd Night Messenger Even Night Friendly Neighbor - I'd say this is equivalent to an IC, so 1 PR point
1-Shot Friendly Neighbor - half an IC, so probably 0.5 PR points
2-Shot Indecisive Doctor - Doctor is a strong role, but this one is severely gated, so 0.5-1 PR points.
Macho Combined Bodyguard Disloyal Vigilante - I'd say this is equivalent to a Weak Cop, which is like 1-1.5 PR points?
Simple Neighborizer - Basically a vanilla cop, 0.5 PR points.
If all claims are real we have 6 PR points. And like I said, our mod likes perfectly balanced games so I feel this might be overkill unless scum has another strong PR (the Alien is a pretty strong PR tbh). However if it were any other mod I could believe all the claims were real. I should probably ask the mod in the postgame if my assessment of this is correct.
So with that in mind, I guess I think it's likely there's scum in the PRs? Mechanically talking, if it's Guillo and Naerys then that would be perfect to put us down to 5 PR points, but I'm heavily townreading Guillo. Maybe davesaz? I could see his role being a scum role. I guess Dunn/Andres also works. Kyoko doesn't work.
I don't think it's Nurse because like Enchant said, he could never just make up such a fake claim and I feel if he was scum his teammate wouldn't make up a role that Nurse himself wouldn't understand. And also he's still cleared by interactions with Gamma.
What I do think this confirms is that we can't have 3 goons this game, because then it would be extremely townsided. So if we kill a second goon (maybe Timmer?), anyone who gets confirmed as vanilla also gets soft cleared as town.
