This is the key right here. Scum nin had a perfect motive to go after Ouro who was bullshitting about his claim. He pushes it hard, convinces Town and Town lynch Ouro.
Ouro flips armourer and while Vere will be under some heat no doubt on Day 3, it's hardly certain he's dead. Ezekel will be vindicated as Widowmaker. While not alignment specific, it certainly makes the whole Ouro vs Ezekel thing appear less like a scum bro saving another scum bro and more a 'He claimed my role, kill him'. Vere and Ezekel come out objectively better in that scenario.
There was no push by nin, tell me why.
You don't put all yours eggs in one basket, it could give town conections later in the game. This is scum 101. It's not very difficult. Vere, Eze and Cherry went after Ouro. You would put your last member in the same group? Even more when Vere was the most suspicious player at that point. If they targeted Ouro and didn't kill him the first day, if they couldn't kill him again the second day there was no way to save Eze. Ouro would be considered cop and we would go after Eze for sure.
