There was a moment when they first saw each other again, after Dean had clawed his way out of hell and hijacked a meat suit until he could get his own back. Just a moment when they stared at each other, realizing what the other was, and was horrified by it. Then the moment passed into ringing, triumphant laughter and a full-on wrestling match in the parking lot of the motel that totaled three cars. Sam's eyes were shining when he finally let Dean win, still the same innocent blue-hazel they'd been back when he was human. Dean stared down at his little brother and realized that they'd be spending all eternity together.

It was perfect.
