Awwww, that was just all kind of adorable! So much cuteness in this I can't even begin ... him being horrifed at finding Vincen't baby brother in that "cage", his campaign on getting one of his own, the book omg!, his letter to Santa *melts*

God, I can't imagine what it's going to be like if Dean did get a little sister instead of a little brudder!

And this - He was going to have a little brother, by God, and he was going to show Vincent and all big brothers the world over how it was done. - oh Dean, you certainly showed them. Dean Winchester - best big brother in the whole world!

Thank you for this, I love it :)
