I'd expected to enjoy this fic for Flitwick--a character for whom I've got a soft spot--but Dolohov just grew and grew on me as the story progressed. Like Songquake above, I love hearing about how Death Eaters became Death Eaters (presuming that only a few are as genuinely bloodthirsty as Voldemort), and this fic really delivered on that front. Dolohov is out of sync with British wizarding society in so many ways--not just the queerness, but his particular family history and his ethnic heritage--and perhaps hampered further by mental health issues...this fic doesn't seek to redeem him, but it certainly does show how the path to Voldemort's side might have begun somewhere completely different.
I also really appreciate the fact that Flitwick was the one in a sham marriage. I've always wondered if his absence from the Order said anything about his own opportunism.
