I am just too filled with OMG and WOAH and NNGGGGHHH to even comment coherently about this fic. Excellent read! Great plotline and so, SO much to look forward to in the future. I love that Harry's obsession runs so deeply that he repeats his actions at the end.
Loved Snape in this, and the Polyjuice scenes were really very well done. So too was Harry's dream about the scars and his realization!
