I think most people are just panicking and are ready to hang anyone. On the first day, they didn't want to hang anyone based on the evidence; today, they decided to hang someone even without any evidence.
Whoever the Mafia was last night – Neyra or Morning – they didn't participate in the second or third nights; the evidence from those nights doesn't point to them.
We can assume a few scenarios.
1. Neyra killed on the first night (compass), Azi on the second (love potion), and on the third (Lenin), and then Neyra again on the fourth.
I don't understand why they made this switch. I always thought that the Mafia uses one killer until there's so much evidence against them that it becomes impossible not to reveal them. Here, they completely unreasonably eliminated Azi instead of continuing with Neyra. If neither of them is the Boatswain or the Witch, then there's no point in replacing one with the other based on the role's characteristics.
But, of course, anything is possible...
2. Azi killed on the first night (rat), on the second (potion), and on the third (Lenin). As far as I've noticed, the GMs usually simplify the evidence against a player if they see that it's not being understood for several nights in a row, so I'm not surprised about "Lenin." Then, on the fourth night, the Mafia calmly eliminated Neyra, who hadn't been exposed yet – but here, their streak of luck ended, and they got a good response.
If these were two conspirators, then this behavior is quite logical – they first used one expendable player to the fullest extent, and then switched to the second, deciding to save the more complex roles.
3. Vishmaster killed on the first night, Slonysh on the second, Azi on the third, and Neyra on the fourth.
Perhaps there's some logic to this, but to me, it looks like a suicidal attempt to expose all the Mafia members.
Without sorting out the actions of the previous nights and finding a consistent pattern in the Mafia's behavior, we'll be executing people randomly, and, as I see from my own example, mainly our own people!
Who will you execute tomorrow, the day after tomorrow? Will you flip a coin?
