Alright, so at least we know he isn't lying about it. For a moment I was considering that all roleblocks were not on the mafia side.
However, as you're going to lynch me I'm going to add a bit of information I've been hiding, as it may be relevant for Louis vs Mojoman.
That gif I'm using as my avatar is one I made myself using footage from my copy of the game. I specifically made it because I wanted her holding a Rapier.
I have a Rapier as my item. I can roleblock people who target me as long as I'm holding it.
So, in the case where ChopBam and Louis are the scum team, there are three roleblocks outside of the scum team, and a scum member who has never proven to use her ability has the ability to undo a roleblock.
