Well...the only way to prove either side right or wrong is to vote for Prosecutor Blackquill, though. If we do that, it'll be obvious if the truth is being told or not...and I'm sure if our side was wrong, that Prosecutor would get outted by Myriam and Daddy.

I don't think they're wrong about this, though, because it'd be a pretty silly gambit for the killer if they could be disproved so easily, wouldn't it?
