I enjoyed this quite a bit. This is a tightly written and quite awesome au. I love that Ellen just takes Dean in and raises him as her own. Love that we don't quite know what happened to Sam and we never find out how John died. Especially like how Dean conflates his failure to protect Sam with protecting and taking care of Jo. Love how you bring Castiel into this, that Dean refuses to let him cure his inability to speak and how, in the end, he comes with Castiel to keep Sam from killing Lilith. Am thrilled that Sam goes to find Dean after it all and that Ellen welcomes him with open arms. And the end was fabulous.
