All this theories of yours are flawed. You know why?
I am a Werewolf.
You see, we killed Azaelia because she was second on the alphabetical list of villagers. Anyone who's second on any list is scary. Add to that the fact that our ultimate plan is to find the cursed villager, who is said to bring balance to this game (i.e., there will be more of us). The cursed villager is probably not gifted, so we kill the silent ones.
Then there's this added advantage--we could put blame on
the phantom, who could shift blame to
Eomer. Because of this confusion, they'll both die. Muahahahaha!
Having said that, lynch me. Now.
Post-traumatic Possum. We intend to kill the gifted villagers through lynching, though. They taste bad.

(Sorry to any gifted villagers there.)
