Dean's been talking to Sammy for months. He puts his hands on Mommy's belly and leans in close, telling his brother about the cookies he and Mommy made, or how much fun he and Daddy had at the park. Mommy says Sammy can hear him and Dean loves the idea that, even though Sammy's not here yet, he already knows he has a big brother that can't wait to meet him.
When the day finally comes, Dean holds his brother in his lap. "Hi, Sammy," he whispers. "Remember me? I'm Dean."
Sammy's silent, but his tiny fingers grip Dean's tight.
