Looking for angsty fic where (slayer?) Kurt has to deal with being enemies with (vampire?) Blaine

[sparklegemstone.livejournal.com]

A while ago I came across a fic where the gist of the summary promised an angsty fic where Kurt had to grapple with the fact that he has to somehow take care of / kill / ? Blaine, who he loves (edited my post a bit because I only read the summary I'm not sure it was necessarily kill) .

I'm pretty sure I saw it on fanfiction.net and that it was a slayer/vampire sort of story.  But I've spent hours trawling ff.net and sadly can't find it.  I'm kicking myself for not reading it when I first came across it--if anyone can point me in the right direction you'd have my utmost gratitude!



I'd also welcome any Klaine recommendations that have a similar theme of it being on opposite sides of someone you care for.
