Oh, this was awesome! I feel bad that it took me so long to comment on it. I read it this morning right before work, and then never had a chance to come back and say anything about it.

But I loved the way you wrote it -- Cas's enthusiasm and excitement about everything, and Dean being a little more reserved and quiet. And their personalities, that are just a little bit more adult than regular kids. I can just imagine Cas rambling on and on about all the things he knows. And “Old fashioned salt 'n burn prolly.”? Probably my new favorite sentence. Little five-year-old Dean planning hunting strategies. Awwww.

...I kind of want to see more of these guys. (psst! What if maybe one night there's a really bad thunderstorm, and Dean is maybe a little scared, but he'll never admit it?) :D

Anyway, great job! Loved it!
