I really don't know what to say, beyond that this made me cry. The good kind of crying, mind you, where you just feel overwhelmed by the beauty and truth of what you've read. I know - sounds like a terrible cliche - but there it is. This is so true - it takes a very deft hand to make me believe in a Severus that wants to be owned, one that has an understanding of where that desire comes from. You have that understanding here, and it works so well. This resonated with me on so many levels - it's got an almost meta-quality to it in Snape's discovery of writing, and his joy in it despite (or because of?) the constraints under which he lives. You paint his desolation so wonderfully, you give him a Harry who isn't perfect, but who takes care of him in the ways he needs - I'm just blown away. I really love this.
