First it's a matter of removing "must be a villagers", that is: Serdoa, Ichabod, Gaspar
Then remove "probable villagers": Catwalk (honestly, too crazy to be a wolf), Injera
Roland is in the suspect list because he made the killing blow on Zakalwe (who saw that one coming?) and his "I sense the villager" abilities. Sareln gets there, because of his invisible play in the beginning of the game and he made a switch from TT to Scooter, while Roland then voted Zak, which made the lynch:
zakalwe (5.1): Serdoa, Catwalk, Twinkletoes, Injera, Roland
Twinkletoes (3): scooter, Meiz, Ichabod
scooter(3):Gaspar, zakalwe, Sareln
Even if Zak and Gaspar both moved to TT or scooter, Zak would have been killed. The only people who could have saved him were me and Ichabod, and we were both sleeping (sorry I didn't count you here scooter)
Also more on this fourpack theory:
Day 2 and 15 minutes before the deadline the situation was:
Erebus (7): Zak, Catwalk, Gaspar, scooter, Sareln, Ichabod
Catwalk(4): Roland, Injera, MNG, TT
scooter(3): Meiz, Erebus, Serdoa
TT made changed his vote 4 minutes before deadline and Roland 1 minute before the deadline, making it:
Erebus (7): Zak, Catwalk, Gaspar, scooter, Sareln, Ichabod
scooter(5): Meiz, Erebus, Serdoa, TT, Roland
Catwalk(2): Injera, MNG
Not possible to get scooter lynched, but looks so damn good if/when we find scooter guilty. Especially Roland's last minute vote without any chance to change the outcome is so out of character.
It's amazing how I manage to find these clues just by trimming my wolf glasses a bit (allthough I like to call them wolfhunting classes!)
