Scootaloo is worried about her wings. They're so small - what if there's something wrong with them? Worry turns into anxiety. What if she'll never be able to fly? That thought scares her more than anything.

Rainbow Dash isn't the most eloquent of ponies. Can she find the right words to cheer her honorary little sister up?

The flu; all ponies have had it at some point in their lives. It's a simple yearly ordeal that leaves you feeling crummy for a week or two, then you're fine again, right? Oh how wrong of a misconception that is. This is not the story of the feather flu, this is the story of the black flu; the worst flu pandemic in Equestrian history.
(There is adult SpikeBelle shipping [as in age, not content] and no, there aren't any zombies.)

Though this story is fictional, I'd like to point out that this will be an accurate representation of a worst case scenario pandemic in our world. And after the recent outbreak of H7N9 in China and NCoV in Saudi Arabia, I felt as though I needed to write this story. So I hope this story will both entertain and educate you.
