Weird turn spot with 2pr - 100nl

[PapalRage]

Villain is 30/1 over 80 hands with a 50% fold to cbet. There was a dead sb and bb posted in CO. No relevant reads besides his super scary looking iron man token.

fold, he's never bluffing/ rarely vbetting worse and the times he is vbetting worse you're gonna fold the river a lot anyway since clearly thinks he has the nuts.

This made me lol. He's sooooo passive. Unless he turns into Mr Hyde post flop, I think this is a fold.
