Well, this is just plain piddle right now. If any of this was true, do you really believe that the mafia would slip up so easily? In fact, you appear to have just said that you killed a townie out of pure revenge, without any other reason. Seeing as in the last few games, vigilante-ism has been a one-shot thing, I find it funny that you would waste a shot on something as stupid as this.
And another thing: what the hell, Taleroth? Are you claiming that Mafia are day-talking? Or did they telepathically communicate to each other the vigilante theory? Because, honestly, you really seem to believe that they would have been able to figure out that there was vigilante who targeted Robb, as opposed to the dozen-or-so other killing roles. If I would have had to guess who had thrown out a kill, other than mafia, then I would have assumed "serial killer" if anything at all. I mean, come on, this is wonderland after all. Possibly with a "get the jester" clause, I don't know. In fact, this seems to be a far more reasonable explanation for your nightkill than the one you provided.
"To avenge Fexen". Yeah, right. Good one.
I say that you are scummier than a three week old boiled egg sandwich that was coughed up by a dog into the gutter. Then eaten by a hobo.
My vote stays.
