That's a ton of Mafia... Hopefully this doesn't hearken back to Dragon Ball Z Mafia in the end.
Well, after what Go Dark Link said above, it shifts my perspective. Originally he seemed to somehow know who the SK was and targeted them to lessen the chances of them getting killed. In the Mafia's eyes, eliminating fused might have been far more advantageous to cover for themselves. With 5 Mafiosos lurking about, it's pretty safe to say that one of them is Mafia Role Cop, which, in addition to their huge numbers, puts Town at a serious disadvantage. Especially if they have a Roleblocker, too, which made a terrifying combination at Night in most of the game in Members Vs. Mods. Ironically, in that game I was the Mafia Role Cop and Go Dark Link was the Mafia Roleblocker, so my background with him makes me a little wary, although it present that caution is starting to soften.
