I was pretty genuine with my scum hunting, only exception was Orca who I wasn't sure on but had as potential scum, and I actually shot him the same night that Poyser did. I thought Tepig had good chances to be scum, especially without being able to explain why he survived, and I didn't have such a confident read on Ekko that I was willing to overlook that. So I laid out my issues with the lynch and ultimately went there because it felt like the best move.
Remember I wanted to lynch scum early, as Serial I'm not comfortable with mafia until I can be reasonably sure they only have 1 left as then we're equal. The only mafia that really blindsided me was Rej who I really thought was Town. I lynched him there because I didn't want to risk Alexis changing up and switching to me when there clearly appetite to flip me, and at that point I was starting to think there were only 3 Mafia though I didn't understand why Fuji wouldn't include Aura. But everyone else felt so townie, including Rej.
I can't really speak to this because unlike me who basically played town for most of the game, I do think Hayumi played it more like he would as scum. So I accept all of this Flower, I just don't accept what you're saying about my play before the penultimate day phase onwards. Because that day (the day Rej was lynched) was the day I felt I could be the only scum left at which point I had to switch up.
