RGk, AL and Ansa why do you suspect them?
Wait, you aren't reading them as scummy?
RGK has done absolutely nothing this game, has looked bad with his 'catch-ups', had questionable interactions with Poison, and for me has tried to look productive but hasn't. It feels like he's playing a sideline game here.
Al, he's not really a top suspect for me, but he's definitely in my POE, probably near the bottom.
Ansa has been all over this place this game, had questionable interactions with Poison, and looks to headed in the wrong direction with his reads and thoughts constantly.
