yes, but it might be worth leaving open the possibility that assessor used their ability n1 to minimize risk of TPR's fudging with their abilities later on in the game when it's less obvious and for WIFOM.
I also think there's a decent possibility that if Unknown/Helz is beguiler or smth isntead then the assessor may plan to simply sit on their ability for ages and let the threat of the ability put pressure on who we lynch.
