Alright, so I still haven't figure out why the Godfather was killed the first night. There are a couple possiblities:
A) The doc blocked the mafia's strikes until his death, and the mafia has neglected to kill since then. An independent serial killer is on the loose that has been using cars to night kill instead of the Mafia.
I just find it unlikely that not one of the Mafia members would bother sending a PM. Doc must have also been really lucky to block all the attacks. Although if this is true, I'm impressed by the Doc and serial killer.
B) The mafia killed their own Godfather. Someway or another, the mafia are related to cars and there is no serial killer.
This is highly unbelievable, but if so then they have some conspiracy plan to use the name claim against us, and by showing that the Godfather role connects to the Godfather's Pizza, ensure that we went through with it and use it in our actions.
C) There is a veteran/vigilante who either have a limited number of kills, or who chooses not to kill every night. Everyone with drive-thrus kills by cars for some reason.
Not likely either, since why would there be car deaths for everything...and if so they were really good/lucky to kill the Godfather the first night. It makes some sense because most town players during this game seem to have roles anyways (message sender, voteblocker) and it would make sense that we had at least one vig.
D) There is a role switcher.
This is a very possible theory, but it may or may not be true. I had forgotten about this role. It fits with the "everyone has a role" observation, and it explains how tire marks were still on the Godfather. I think we should look into this one.
E) Some sort of combination?
I think there may be some combination of the above, though I have yet to figure it out. I'll let you know when I do, or maybe one of you can.
