Firstly: if you really think the vig is scum you get to provide an alternate explanation for the kill setup night 1.
secondly: weren't you saying your role was risky to use earlier?
Thirdly: heh, that's part of why I wanted to see you talk; had you claimed you had gotten a message, I'd have been laughing. And hammering. But mostly laughing.
Fourthly: I'm forced to note you haven't even proposed who you were going to bus, not like it matters too much with the roleblock.
Fifth: Just because you haven't been forefront suspicious before doesn't mean you aren't now. That neither proves nor disproves anything, and, say, presuming El Cid is scum:
He has the miller vig.
He has the roleblocking doctor who cannot block any of the other three without risking blocking an important role.
He has the bus driver who can't block himself, IIRC, and thus can only swap around one other target.
He has then you who seemingly hasn't used his abilities since the beginning.
Targeting you seems the most ridiculous of the options, especially since the miller vig is pretty much soft-confirmed, I know I'm town and apparently I've made my case well enough, and the Rat was likely mafia targeted and thus not mafia himself.
These three he cannot easily throw suspicion on.
You? Would be comparatively easier. Not as easy as perhaps say Bardiche, but you would still be an easy person to foist this off on. There's no real advantage to targeting you over trying to kill one of the three people that can be more easily trusted.
Edit: Bardiche, hate to say it but from our position you'd be the most obvious one here, especially with your pre-emptive information. El Cid... well. Lemme glance through again quickly but I seem to recall thinking about sound and fury with regards to him, though again, different playstyles.
One disturbing possiblity has come up in my mind and I really don't like it. Let me think about this for a moment, but... mmmm.
