An encyclopedia of weirdness

Yes! To most everything you wrote, especially with Dean hanging onto Sam with fierce love and determination. Except: It was always my biggest fear that Sam goes evil. I am okay with him flirting with darkness and being misguided, but I don't want to see Sam commiting acts that are unforgivable in his eyes as well as the eyes of the viewers. I do have a clear limit there and I am afraid that they cross that line and destroy the character for me. I want Dean to save Sam before he goes over the edge. That's why I am anxious about how the season plays out. :)
