I love this insight to Snape. It is so IC and gives him so much more depth. I like that the whole fic seem to expand on what happened in the books. Your use of canon here was fantastic. Snape is so focused on doing what he must that he gave up so much of himself. He seemed to be addicted to repeating those past experiences in order to keep himself going in the present. Harry's reaction to the memories of what Snape did to him was classic. And I like that you had him request that they all be removed. It gave them a chance for a new beginning in the epilogue. And such a wonderful epilogue it was! You have wonderful writing skills and the enviable ability to really see into your characters. Such a great revisit to Occlumency fics of past with the added information of the end. A truly great fic!
