In 1.21, Sam and Dean have to save Monica and her daughter Rosie, for the YED making her part demon, presumably. Why was the YED doing this is 1) Rosie isnt the other "children's" generation?, and 2) if itd already happened to sam?? Thanks!
I've thought about that, too, and I've come up with two possibilities: a) Maybe she was insurance in case none of this generation survived, or b) maybe they're preparing for another apocalypse, in another generation.
