Let’s see. Gaming this out:
It’s barely possible that there’s a Scuba/Chronos scum team (how would this work? Scuba is an alpha and Chronos is a vanilla scum. Ichini was a dupe), in which case the scum win. Alternately, Chronos could be a fake Mason, which seems overly gastardly to me; if he has a partner in crime, it’s pretty hard to see the scum losing this game.
As Chronos has pointed out, a Cold + Cookies team will win as well.
Other possibles are:
1 - Hal + Darth. Hal flips scum, Darth either:
(a) tells the truth about Cold, no night kill. That leaves open the possibility that Cookies is the only scum, who deliberately held off on a night kill to frame Darth. Town can lynch Cookies while leaving Darth in jail, find out that Cookies is town, and then lynch Darth.
(b) lies about Cold, no night kill. Town can lynch Cold as above.
2 - Hal + Cookies. Hal flips scum, Darth reports Cold as Town. Cookies is toast, whether she night kills or not.
3 - Hal + Cold. Hal flips scum, Darth reports Cold as scum. Town wins again.
4 & 5 - Darth + Cold or Cookies: Hal flips town. Darth can tell the truth or lie. If town lynches the scum of (Cold and Cookies) and keeps Darth in prison they win. If they lynch the nonscum, they lose.
6 & 7 - Cookies alone or Cold alone: The flip side of 4 and 5 - Darth can correctly ID the scum, the scum can claim Darth is lying, and someone has to make the call. If town believes Darth, they win; if they don’t, they lose.
8 - Darth alone. Town has basically already won. There will be no night-kill, they can lynch whoever, and when there isn’t a nightkill again they’ll know to finish off Darth.
9 - Chronos alone, as a fake-mason role. I think he’d basically have it won already: night-kill Ben, lynch either Cookies or Cold, then night-kill the other and win.
So basically if Hal is scum, and assuming no scum power roles disrupt this, town has won. Otherwise, it comes down to whether town trusts Darth or not. Whee!
