Idk I think she can be town lol.
If you take a brief look at some other games she's played it's clear she knows what she's doing. I would only town read her here if frankly I assume she's just a bad player because how they read into you/Flower's very mundane reactions as a grand conspiracy.
I mean basically here's my argument:
I think Flower and Fuji being the first to discuss the alignments and the killer robot crew probably wouldn't come from scum, too bold at the start of the game even if they have fake claims. This would put them firmly as town for me
This is Orca's interpretation of you/Flower's play. Very reasonable and likely close to the truth. Doesn't take much to assume you both faking that sequence is unlikely.
Now account for the fact that Orca isn't even that good as town and I'm pretty sure Butters is kinda good?
