Neyra was obviously the murderer, hence the dragon emerges. The only thing unclear is why she simply beat up Lizard, but also burned Hermit.
Cash's bump on his forehead might indicate that he ran into someone with strong protection (hence the sour expression). Besides being a noob, this is another argument against him. If so, it's possible that he and Neyra went to kill Hermit together – one failed, and the other finished the job. I don't know if such a scenario is possible according to the rules of this particular Mafia game, but it's not ruled out.
So, for now, let's "eliminate Cash in the bathroom," and then we'll see. If necessary, I'll reconsider.
