Dean's mouth fell open. He should have guessed, as John wasn't that common of a name, but the news was still a pleasant surprise. "John-Nathan Noah Winchester." He said the name slowly, putting an emphasis on the second part of the child's name so that the three names were all evident. He leaned over, rubbing Claire's arm with a pleasantly stunned look on his face. He could still hear Natalie's voice chattering away, and no doubt he'd find amusement in the story later, but right now all he had room for was awe. They had three children...four children if you counted each of the Bens individually. He was practically an old, settled down, married father of three, and he couldn't think of anything better.
"You're getting a little brother one of these days." Dean said, a pleased look on his face as he leaned over to ruffle his younger son's hair. "Hopefully you won't teach him all of our bad habits."
