I was relying on my ability to kill her and had convinced myself there were two scum left because I figured Warlord Zjini would make the game and thought Lawls' claim was too obscure, so I killed him and basically lost the game doing that. My intent was to use Crofty to kill the "other" scum player I convinced myself exists and then kill her immediately after. Didn't really occur to me she was BP. which sucks because I was really sure Titania was one of the final scum (along with Lawls). Sometimes having theme knowledge sucks and clouds my judgement.
Also I believed sXe's claim. I was just sick of him tunneling me.
