“That was the Mark.”

DCcon 2016 | J2

Sometimes I kinda feel a bit sad for Jensen when questions like that come up. He did a fantastic job with showing us a Dean in season 9 and 10 who was losing himself more and more, and showing the Mark taking over. While Dean certainly has some dark sides to him, I think Jensen played the change and the difference the MoC was making very well. Sam has always been Dean’s world and he died three times already just so that Sam could get a chance to live. So that question about that scene was never a question for me.
I know lots of people saw the difference, that it was the Mark, and I hope Jensen knows that he did a wonderful job with this. :)
