This was a very well-crafted story. It unfolded plausibly with a still-recovering Snape going to Harry for help. Both head off on a slow ship journey to the Falklands and tension builds nicely between them as they slowly get to like and appreciate one another better...much better. The ending was wonderful!
"No. Don't— just... don't. I owe you for everything you've done to help me, and... we all do things we regret. Things that we wish we hadn't been forced to do. When I saw your memories, I..." Harry smiled faintly, uncertainly. "It doesn't matter what I thought. But I'm not as angry as I was, you know? I don't blame you entirely." And now his emerald green eyes met his head on. "So. What can I do to help?"
I loved this. Harry is simply note-perfect. He still has issues with Snape but understands why he did what he did and is willing to let bygones be bygones. This scene was exactly what I wanted desperately to see happen in Book 7. Thank goodness for fanfiction!
