The always running Barry Allen, is going to need to get much faster in order to outrun his high school years. Taking place in season two of The Flash (with a few alterations), this crossover shows just how hard it is to keep his multiple aliases away from each other. When his old friends (and enimies!) show up, the people he cares about need to know the truth. But Barry will try to avoid doing so. In all honesty even I don't know what will happen. I do not own any of the characters in this story. Please do not sue me.
