lmao, WhatPumpkin accidentally revealed Marvus's sign; he's a Caprist

“Marvus briefly had a hat on in the TROLL CALL. That wasn’t his actual sign, though. Marvus is a trickster, AKA, a lying piece of shit. You’ll have to wait ‘till ACT 2 to see his actual sign. Never trust a clown, kids. They’re addicted to pranks.“

It would seem you have been tricked, my friend. You played right into the Clown’s tricks. And so did half of the Fandom.
