Dean was paralyzed in the same position after he delivered his blow. He was holding his sword in middle-air, one of his legs was totally bent forward and the other was stretched; his back was slightly leaned as well. It was the standard position when making a full swing. Dean's body had learned how to do it even in those dangerous and unpredictable situations.
'I don't feel anything around anymore. That pressure is completely gone, I guess. Did I do it? Did I kill Rick? Is this the end?'
Dean tried to search in his heart for those chains that were attaching him to Rick but... he didn't feel anything. He got ecstatic all of a sudden. It was good the feeling of knowing that you can decide your own things. He wasn't enjailed anymore!
'It's over... However...', Dean opened slowly his eyes, looking at Rick, who was still in front of him.
