An enjoyable read. I really like your Snape. He wants to die after the war, but maybe because he's never really lived.
"You save them and set them free, and you don't use them for your own ends." Snape pauses and Harry hears the rumble of many voices punctuated by loud requests from the press at the other end of the main hall. Harry takes Snape's hand and quickly seals them into the Visitor's Entrance lift. "I've never encountered someone like you before. You intrigue me, Potter." Perfect. Harry put Severus off balance because he didn't expect anything from him. He gives Severus a choice, something he's never really had.
