Oh, excellent. Though if you and Cazero are both wolves I will be very sad.
My two aspects are Perceive and Negate. Negate lets me block a night action. Perceive tells me the names of the aspects I'm blocking. I used it on Persolus N1 (Negated "Discern" and "Twist"), Merel N2 (Negated "...?", which was explained by you having stolen her power), and Negated Caohimn N3 on the offchance he wasn't dead (received "...he's dead. Gone. Blasted by the heavens." in response).
You can see why I kept this in the back pocket. Blocking a wolfkill this late in the game could win us everything, if I don't have to worry about it being stolen.
