I love seeing the boys' relationship from another's perspective...Even better that it's Bobby. My absolute favorite part...

He laughed as he watched Sam chase his older brother across the public park in front of the motel, easily catching up with him. Those boys didn’t get much chance to behave like normal young people, let alone brothers. He was just taking a big sip of coffee, ready to turn back 17th century trial accounts, when he saw Sam pull Dean around and plant one on him.

Dean let him.

So great! Wonderful job.
