Sometimes, what usually isn't possible, actually can be once you try it out. Rainbow and Twilight discover this with the help of friends, through a simple experiment.

A bout of sickness causes a rainbow maned pegasus to wander over to a friend's place late at night. However, while no cure is found, a universal remedy might be created under the starry sky.

Magic is an extraordinary element, as Twilight knows. But what if revenge is taken upon her, by somepony with magic which surpasses her own. What if this magic alters her mind? What if this involves a pony she loves? What if this involves Rainbow?

I like to believe that I am the strongest of anypony I know, that I have no weakness. And I like to believe that I am the strongest out of my friends, for certain reasons. I couldn't be more wrong.
