One of ruby/rue has got to be wolf and if ruby is telling the truth, rue was at the very least healed/jailed Jarek is the only one so far who has claimed a jailor-type ability, and I do not see why town would jail rue (i also don’t think anyone claimed it)?
mafia had to have jailed rue to protect them; i don’t see how else it would work.
I guess ruby could also be lying but I don’t understand why they would like this
