Their co-dependence is amazing, incredible stuff. I CANNOT BELIEVE THAT SCENE at the end last night with them. I love how Sam let it all hang out, all that pain, and how Dean responded. You see how they feed into each other and you know - this is one of those shows you will always remember. I've had a few - S&H of course, ASJ, POTA, and now this, but the intensity of the leads, their chemistry and their feelings for each other, that crown belongs to S&H and SPN.
