I didn't forget, I simply didn't include because they're both extremely improbably scenarios. According to Fali's own role description that she herself provided, she needs to preselect her targets for using an action on them the next night. The only way she's hitting mafia is by having ignored the suggestion to mark me for action use on the following night and somehow managed to hit a mafia instead. First part is possible, but somewhat unlikely in my opinion, the second part has the numbers against her. Put those two together and I highly doubt Fali's going to be of much use to the town against the mafia in the next night.Faliara has a very good chance to hit a mafia and that mafia can still hit the samurai.
As for mafia hitting a samurai... why would they, when they can just take out the confirmed townies instead? Ltin for example, he's basically a free target begging for a hit at this point. The bulletproof vest might hold them off for a night, then the optimal play for mafia and survivor both would be to force a no-lynch quickly and win the game the next day.
And I hope it goes without saying: this is, of course, in Vatu's fantasy world. Just in case someone wants to call a "slip" on me.
