Everything has fallen apart for Scootaloo.

Her Cutie Mark will never come. The doctor said so. Her blood is just wrong.

As she stays in the Cutie Mark Crusader's Clubhouse, her friends show up. Now she has to explain that her crusade is over, and that there's even worse news.

Life as she knows it is over.

A/N: Kind of a sad story, with an upbeat ending. Listed as Slice-of-Life because it contains headcanon that makes some modicum of sense. Pretty light (Scoot's not even an orphan in this), and may have been done before, but this idea's been bothering me for too long, so here it is. Bonus points if you know what the title means. Avoid comments for massive spoilers, even if you do know what the title implies.

And yes, I do have some background in genetics, but I'm skimming it a bit for show feel.

Edit 28/7: Made the whole thing a little longer, and I think better in general. Hope you enjoy!

Watch out for the sequel, being worked on now.
