This all sounds good - letting the wolves know that you know the best player, and therefore who they are likely to hit. also lets the doctor know who is a very important player to keep on board. however, if charlie, ice, and coler are all wolves, they may be fooling the doc and using this to keep their own personal 'special role finder' in the game as long as possible.
If we were all wolves we wouldn't chance hitting our own guy on a chance that the Dr might protect him. We'd wait till he was lynch bait then try to talk the Dr into it.
