Mmm, *nice*. Nearly every line from Snape had me laughing, even though his horrible relationship with Harry was painful to read all the way up until they finally started to get along. Minerva's intervention was a wonderful scene as well as a turning point, and I liked how after that Harry began to have a bit of parity. Snape's starting to fade was so poignant - another turning point, and a great set-up for the twist ending.
Your Minerva was fabulous, the other characters so nice to see, including Dumbledore, dropping oblique hints as always! And OMG, some of those lines of Snape's are so totally what fans may have been wanting to blurt out for ages, lol.
I stayed up too late with this fic to be making much sense, but I wasn't about to stop reading! I loved the whole long ending, when Harry finally got his courage up to go to the crypt, and Hermione had apparently found the right spell, and then OMG, his sorrow at the lack of results. I was crushed! Thanks for not leaving it there! That would have been a good story, too, but I was rooting for the happier ending.
Now I'm visualizing the two of them on their travels, bickering like the arrested adolescents they are, and both finally becoming the people they can be. You really made this pair come to fit together in a logical and natural way, and I love this fic so much for that especially.
That very last line of Snape's is so funny. Yep, two adolescents. Hopefully Snape will never realize how much he sounds like a Marauder...
