Look at the bottom center. I have watched season 8 so many times and I didn’t notice Castiel’s hand squeeze. He is doing that so he won’t hug Dean back. Because he’s about to run again. Because he knows Dean will want to find a way out but Cas doesn’t think he deserves to be free. Because if he lets himself hug Dean back, it will make separating again that much harder.
