Double Rainboom. We all know this one; a fan-animation more concerned with its meme-count than its editing or jokes. And in the center of this rancid Cadbury egg was a weak story. So, here's my attempt at making this story interesting, without changing the premise... too much.
Rainbow Dash has just been let out of the hospital after the events of Read It and Weep, and discovers Twilight's hobby; a Talent-Enhancer. After agreeing to be the test subject, she sends herself hurdling through time and lands 30 years in the future where Evil took over in her absence. From there, everything goes wrong.
