Reading through all your hurt!Sam fics and loving 'em! I always love discovering new (to me) good fic writers. You're great!

Psst... just one minor correction you might want to make to this fic, though. If John has type A blood and the boys have type B, then Mary's been cheating on him. If a father has type A blood, the children can only have types A, AB, and O, depending on if the mother's blood type was A or O (for type A), B for (AB), or O (for type O). Just changing John's blood to type B and the boys' to type O would mean John couldn't donate to them and yet still be their father.

Yep, Sam would definitely give his blood to Dean. Wonder if that gives Dean demon's blood too now?

great job.. would love to see more from it..

Methodology: Very informative. Sam: Very self-reliant. Story: Very Winchester!
