Yay, I loved this, and I'm anything but a fan of 'moving to alternate realities to escape' plotlines usually. But this was absolutely delicious. Regulus, wow! Snape's alter ego, double wow! At first (having downloaded only the story without header information) I had no clue whether it would end up being H/S, H/D or H/L, so the guessing game was double fun.
But the Snapishness of Mr Crane was evident very quickly, and I loved to see Harry's potions obsession (and the way Snape didn't let the poor boy breathe in between work).
The romance, when it comes, is wonderful in its fragility, with Snape skittish about commitment and publicity, and Harry hell-bent on restoring his name because it's the right thing to do (so, so Harry!). I was so very glad to see Snape relent in the end ('cause he's the type who could throw away a good thing for pride's sake).
I laughed my head of at when Harry deigned to start a conversation he was met with a look that would singe a Chinese Fireball's whiskers.
Though as much as I liked this fic, I think I hate you for siccing the most aggressive plot bunny on me I've seen in ages, with Your first and only marriage was to Voldemort. Brilliant, brilliant line!
Wonderful fic, too :). Thanks so much for writing this!
