This was beautiful and amazing! I love the relationship between these two, and you have them perfectly characterized. You even made me like the kids! ;)
I almost felt like you were inside my mind - as you seemed to have the same issues with DH as I did. I loved Snape's anger towards Dumbledore, it felt very apropos.
I almost hate to mention this - as it's such a small thing with such a wonderful story - but there are quite a few typos and missing words/wrong word placement in this fic. Just a heads up if you plan on archiving.
And lastly - I adored the ending - Snape finally feeling Harry's hair! This fic really moved me, outstanding work! ;)
