I think it's most likely EP is the Human. That is why they claimed/counterclaimed and why darg's defense was limp AF while EP was the pinnacle of erudition and poise. I also think worcej is likely scum and pushed Chaqa to try to drive the cow target onto the wagon and make a super-ultra-combo turn. Chaqa happening on D4 provided breathing room for the tracker claiming and also gave time for town to get fat and lazy on two scum lynches in a row, making it more likely town would give up on the fact that EP is still obviously scum.
If I understand correctly, if we mislynch today it's MyLo tomorrow, so I don't want to get distracted from the fact that it just makes absolutely no sense for EP to be town. I don't know why anyone would vote for worcej instead.
