I am lead to believe that there is no SK. A no NK the first night would probably have been the doc saving the right person then. My belief is that the doc messed up night two, and that lead to Kyby's death. Dat is my assumtion. Or night two, the doc saved the person who was targeted by SK. Could also be that night one, there was a roleblocker that blocked the SK or mafia, and the doc saved someone too.
Just wanted to point that out. :\
Are you implying that you're the doctor or perhaps the vigilante with this post? Because earlier in the game you said the town couldn't afford to lynch you. Or are you trying to cover that you're scum?
