I recommend sleeping.
I haven't actually read anything close to EOD2, decided it wasn't worth my time if I was just going to replace in with the thoughts I had already, and I should catch up when I can.
Yeah I'm worried about overgeneralizing someone who isn't as entrenched with mafia behaviour, which is why I'm not strongly townreading Niek and I'm kind of worried about his placement. I've made mistakes about new players before, but I would like to think they're the very not very self aware ones that don't really know what they're doing at all. Hard to explain, and I may be deluding myself, sure. You also gotta remember I was pretty convinced that Niek was scum and Prims was killed for his sins up until I examined his own angleshoot and he responded... fine.
And yeah, daytalk coaching is really something that is dependent on Niek's theoretical partners. Both you and Duskfall would do it; I would find it a huge surprise if anyone else would encourage him. That said, it doesn't rule out the world where Niek literally did forget scum have daychat and joined halfway through and decided to out that for towncred, because it was true.
