Does this really need explanation?
Let me ask you if someone is obviously Scum but you also strongly suspect someone else & they are gonna escape, u will kill the one that Town already agreed is Scum or other one?
Nana was already Scum in eyes of most players, so no need to do anything to her, she was gonna die anyway
But i suspected Xlaw strongly at first & feared that he might fool Town somehow, so i decided to use my ability on him
The post you quoted proves that i indeed strongly suspected Xlaw
Ofc my read was wrong, but it doesn't change the fact that i really suspected him
Hours after that, Xlaw started to be more convincing & genuine but i was asleep & forgot that i even sent that Action
