I'm skipping replying to most of your post and starting with the fact that we should form a Snape is not dead denial club. I was sooooooooo upset when she killed him. I don't know why all of my favorite characters are always killed. Albus then Snape, oh and it's traumatic to watch you're first favorite character kill your second favorite character for the greater good. (I didn't think Snape had really turned dark for a minute.)

But, I like your idea. He's totally in Spain.
