@Reticence:
Well, in the off chance there is a scum a bus role... Say for example Arlee. I do not doubt Arlee's role at all. I'm mostly certain she's town, but I'm not 100%. If she's scum, and knows who I have been targeting... she could make my role quite useless. And even if Arlee is town (I much lean this way), then there is no knowing if there is a scum counterpart role.
That's one answer. I might be missing more. I'd like some more opinions on this before I reveal who I have been targeting. Not sure it's even a big secret or anything though. If I tell you you will likely go "duh".
