Well, this leaves five possible conclusions, all somewhat likely:
Orcinus Duo is a bodyguard (either faction), trying to block a kill from the opposing faction:
I view this one as possible, but unlikely. Paperblade and Jalmont would be better to protect assuming they are village, and Itchni was/is the most hopeless cause for the mafia, if he is mafia. That said, he could be a target for a vig/wolf due to his scummy behaviour the previous day. If he is a bodyguard, he is likely a scum bodyguard.
Orcinus Duo is a Mafia Inspector:
Out of the "Orcinus Duo is..." possibilities, this is the most likely. It had been highlighted numerous times the previous day as playing like a power role, meaning the mafia would have much to gain from checking him out.
Orcinus Duo is the village Inspector:
He has widely encouraged an inspection of myself or Walrein. I can't see him inspector Itchni tbh, but it's possible and almost probable if you spin the facts the right way.
Cereza is lying:
Possible to save what is otherwise a hopeless case. This really needs to be considered more.
Itchni is lying:
Very unlikely but here for the sake of completeness. He would have no reason to cast doubt on the neighbour if he knew Orcinus was the neighbour.
These are the only five possibilities I'm getting. If he was a safeguard we wouldn't know this, and the only other possibility is that he's a scum hooker, which would likely be coupled with an inspect anyways. So, there you have it.
I personally lean towards Mafia inspector or Cereza is lying, but take your pick.
