Well, I saw the Balloon innocence coming, but I didn't imagine JK to be a cop.
If anything, I actually thought he was a civilian.
Now, Paceboys and Prizyms were random votes. Even Darth stated that his vote for Kraby was random.
But, wait... Why was he killed? All he did was vote for Kraby, with a random vote. He even said so.
Now, this doesn't prove anything. For all we know, Kraby is a civilian, and Darth was killed to show that he's the mafia.
Or, they felt threatened by Darth, so they killed him, as he was really close to getting Mafia.
So, in a sense, we can go for Kraby, if we wish.
But, hold on; What about JK? He was killed, yes...
But maybe he was killed before he could search Dessern. Or even Pace, or Prizyms.
I feel we'll need some further investigation on this case, my friends. This could go in many directions, all without the help of the detective...
