while it's possible, i don't think it's
especially
likely that titus is a roleblocker under the scenario where she's scum
the main thing is that scum must have known that dannflor wouldn't report a PR result/action the next day
lots of roles can do this -- e.g., rolecop, jailkeeper, tracker, gunsmith, motion detector, etc.
and that information could have been gained from another slot, too -- e.g., gera
the jailkeeper possibility is a little scary. mafia jailkeepers are apparently uncommon though. and i don't think it actually accounts for town power that well here given that it would actually make my vig role more powerful by sometimes keeping me from shooting an ally (the scenario where i vigshot the same person that mafia are jailkeeping). if town is very powerful, datisi would assign scum roles that are more reliably pro-scum.
so my leaning is that we should ignore the scenario.
You can't step in the same river twice.
