You've found a brilliant way to subvert the ending we all love to hate--whisk Snape away to an alternate universe--truly defining the term in this story. I love all the changes you pictured, and the whole idea of Harry growing up with a loving mother and a father who died to save them. And what would Snape have been like if he didn't have 17 years as an ex/current Death Eater spy, and no sex? Lovely to think about and even lovelier to have our embittered man get to have that life after all the struggle. And I also loved the way you created Harry--smarter, secure, determined, sneaky--the perfect Slytherin.
