Alright, sorry I am late. I guess I have some explaining to do.
I'm not scum. In fact, I'm the doctor. My name is Dr. Feelsgud. I win with the town, but the flavor of my character requires that I have sanity. Basically, I'm a doctors without borders type and although I am sane and an out of towner, it is my duty to protect the insanity of the people in the town because although I can provide needed medical attention I can not interfere with their lifestyle. I need to insure the town lives on, not because I am a member of the town, but because it is my doctoral oath requires it.
I hope that makes sense, I'll explain more if need be. Obviously, I was wrong about Cam and so was KevinH. Although I was wrong, notice my failure in suspicion never lead to the death of a town unlike others who actually have a voting record indicating that they have lynched townies.
So, yes, I'm sane but my victory condition is with the town. I believe my voting record will strongly reflect my benevolence and non-interference.
If I'm left alive my night action will continue to protect Cam, because he is now a known townie. I protected him last night after Alternate_Tree's reveal. It is my understanding then that this is why there was no lynch, not because there was no attempt, but because I prevented it.
