Sam's choice not to be a hunter any longer has been very saddening. I was very upset to see S5 Episode 2 to find out that he quit hunting, thinking himself as dangerous and splitting up with Dean. It was a heartbreaking moment. There are many fans of Sam but for you out there I think that Sam has made one last decision, being the vessel for Lucifer, after this takes place its all over for our dear character Sam... Or is it? I think that it's going to be one sad araw in Supernatural when Lucifer takes over Sam's body. Dean is being forced to have to kill his own brother, well not his brother, but his brothers body. It will be hard for him none the less I do believe that it will be very sad when this episode takes place.
