This is from a theoretical standpoint, and something I have thought about earlier.
If you want a scum dayvig in a game, you have a problem. The biggest problem is that scum could "outshoot" town and take out enough towny looking players making lynching in endgame a tough job. There are two roles capable of stopping this, if you don't want to give away the problem with a day-doc or day-blocker. The simplest solution is the bulletproof. However, if you think about it, this is very little defense against a very powerful scum. Then the next role is more odd: the Nexus. The person which makes sure that all actions directed at him will target some random other. This one also can't get shot. From this viewpoint, Rayfrosts claim points to Vi possibly being, with or without a team. (Day-SK's aren't unheard of, but we'll leave that to the mafia).
Then, the last solution to the problem isn't an actual solution. It is giving the town more shots so that they won't be outshot: Gamma.
This all breaks down if you notice that RF can't also be targeted by duels. It's odd right from the start as the duelmechanic is Spyrex's baby, and this is forcing a RF lynch. It would be a defense against both Gamma and Vi, and seen the problems Vi alone would give as scum, both are quite out of the question. Ray's role, taking that into account, points to gamma being town and Vi being not part of the mafia (though day-sk is possible, which can be left for endgame) and RF being scum.
Rayfrost with that suddenly shot down my townread on him.
