I think that it's unlikely that Dream and Bunny are mafia together. For me, that leaves Bunny-Will or Dream-Will. I think Bunny is more likely mafia than Dream, so I think that team is more plausible. But I could just be burned from previous experiences when Bunny was mafia, I'm not known for my perfect reads, especially early.
So for me, in isolation, it would be Bunny-Will >> Dream-Will
