OK finally caught up, here's my morning summary of how I see things at this stage.
Some clear scum (mafia/bad guys) and Town reads
At the start let me just say that based on what we saw I see 2 suspects; ACS (major suspect) and Tobes (minor suspect). I'll give my reasoning below.
I also have some fairly strong town reads on a few players and I'm sure others are getting the same, so if those are accurate (my track record is not exactly perfect) we should have a solid block of highly-probable townies who can help make the right decisions (lynches and exploration choices).
In this game it's even more important than usual that we make the right choices as a group, usually it's just lynches we have to worry about.
Chaos death
Seems like a ghost killing for sure. "This latest death is not like the others". We have ghosts for the first time due to two Day 1 killings.
Day 1 killers
Like the first kill both bodies were long dead, so as others have pointed the two voices heard night one must both have been killers. I got this wrong as I assumed the deep voice was DPP, but it couldn't have been. I still think they entered and escaped via the chimney though...
Mud trail
What is the significance of this? Does it give another clue as to what we're dealing with? Does anyone know of a movie it links to?
Gunshot in the dark
At first I thought this indicated a Vigilante type kill, as the killer seems to be from one of us players:
"A shot fires, echoing round the pool". "Nobody came in or out of here, the door had been closed all the time. The killer must be right here! "
And the method of killing (a simple gunshot) seems more in keeping with a Vigilante than a Mafia hitman or SK from previous games.
Mafia hitman seems to link to the baseball bat so I'm sure another kill would be more obviously mafia activity.
Similarly SK kills in the past usually linked to rather unique kills as they often tended to keep trophies or kill in a particular way (a hatchet/axe etc.).
Vigilante kills have pretty much always been gunshots (usually headshots as in this case) so it would be the obvious choice.
HOWEVER (I only realised this later) the one thing that doesn't make sense though is that player 21 (i.e. a non-player) was killed, and a vigilante would target a real player obviously, so I don't know what to make of it.
Personally I hope we do have a vigilante role as it means we have a killing role on our side.
BobbyD killing
Killed by a club, what role would have done this? Is this another Mafia hit like the baseball bat? Not conclusive.
Similarly to my reasoning above I don't think it looks like any other roles we know about from previous games (Vigilante or SK) so I would guess it's a mafia hit, as there wasn't another one last night. And by mafia I mean Warden/Guard team as I think they seem to be one and the same thing i.e. the primary bad guys.
my 2 suspects at the moment: ACS and Tobes:
ACS
BobbyD the detective seemed to be going for ACS on Day 2 without really giving a reason why. Knowing he was the detective the most likely scenario is that he investigated ACS on night 1 and saw he was scum (bad guy), and then voted for him on Day 2 to see who backs him or tries to save him.
I did not see BobbyD go for anyone else really so to me this means that BobbyD was killed by the mafia because they knew he was onto ACS, which made them realise that he must be an investigative role as he did not give much of a reason for going for ACS (as far as I can recall).
They knew killing BobbyD would point a finger at ACS but if they believed that BobbyD was an investigator it would be worth the risk, as he was a very powerful role for us.
For this reason ACS is my #1 suspect.
Tobes
Valley suspected early on that there was a link between Chaos and Tobes, and we now know that Chaos was a guard.
Valley was quite vocal about his suspicions and Tobes gunned for Valley as a result.
I had Tobes as one of my potential scum reads so I kept an eye on him, but it's nowhere near as concrete as the evidence against ACS.
Tobes is suspicious for these reasons but there is the voting last night in his favour, so he's only a minor suspect for now:
Chaos voted for Tobes and it was a 5-4 vote at the end so pretty close, a risky strategy if they were teammates. It might have been so that he can jump off him to Valley but it would make it quite obvious that he was saving Tobes.
I vote ACS.
Direction for exploration
I think we should go West to the waterfall. Hopefully there is something to see (maybe hidden behind the waterfall), and it's higher ground so maybe the view will help us decide the next direction.
But I'm not dead set on it, we need to discuss it as a group and see what we think is best.
