Because it was SO out of character for Dean, I know think more and more that it WAS Chuck’s writing to the point where SAM convinced Dean that this is wrong and that he had to listen to Sam and put the gun down.
I can totally accept that as an interesting plot point, but I just wish that was made more clear in the last scene, maybe with Dean apologizing or looking stunned at his own action….
HOWEVER, we may still get that next week as we were left with a cliff hanger.
I really did enjoy this one despite the mess and confusion. I want to believe that was intentional.
