I'm looking for fics that use the Sectumsempra scene as a POD. Something along the lines of Snape being otherwise engaged thus unable to fallow Draco around that day and there being no one to stop Draco from bleeding out.

For some reason that scene has been bothering me lately. It's just such a good place to start a fanfic. The stage is set and all the world building has been done. And the differences stemming from it could go in so many different ways. Dumbledore staying alive but weakening by the day alone could be used to great effect.

So it's impossible that there aren't fics that use this, but I can't think of any. So can you guys point me in the direction of one?
