I don't see why she'd claim it otherwise, since she wasn't suspected by anyone so it's not like she was saving her life by doing it as Mafia. If the real rev dies it seals Notty's death and I don't understand why she'd do that
I mean her actions inside the council last night really set her up as scum, it was fairly obvious that she was gonna be the number one target today. This is honestly the smartest move scum in her position could do as she's created or atleast trying to create this niche for her to sit in where she's untouchable, both threatening the town and also trying to convince people they need her making her unlynchable.
Ergo when I called her a mafia cult of personality lol
If we give into her even for one night and assume she is rev when she isn't the amount of benefit mafia gain is insane whether it be picking a dictator or even just targetting an inno instead of her (completely ignoring the possibility she may be a mafia pr role/granny thus having another night to use her abilities for evil).
Saying if the real rev dies is silly because they may die in 4 nights for all we know, if she had claimed civ she wouldn't survive the night, especially after we were originally planning on lynching her today. This gives her surivivability which is why she's doing it, to survive.
