Yeah i pretty much made DAMN fucking sure if PGO gets priority and trumps ALL including roleblock/protection (such as scribble), and any kind of piercing effect.
Once I made sure from researching and asking the right questions and checking mafiascum etc, i realized that I was the one that killed What for SURE.
And that's when I took the risk for the gambit.
I'm not surprised that Rosie figured I was PGO, but as a PGO i HAD to hint at town to "stay away from me, shit's crazy here" so that I don't accidentally kill off town power roles like Pass actually mentioned. (pass i had already done that in my posts even if u did not see it per se).
I got lucky i guess that Rosie got stubborn over me and my vig softclaim to confuse ppl as to who killed What.
