Seamus is fairly experienced, from what I gather, and so is probably the sort of person that could pull this off. Secondly, I voted for Seamus yesterday, and possibly he took offence at that. Maybe he thought I was a threat to him, and decided to kill two birds with one stone by murdering Seon and getting me lynched.
That could just as easily be used to argue that someone is framing Seamus.

Recall the Vespasian game? I kept saying, "Woah, look at these lynches and night kills! Someone's got to be framing Ishmael."

Yeah, that didn't bear out so well.
