I have been a fan of Nick Scipio for a long time. His Summer Camp series is a favorite. One thing i like about it is the opportunity to run off on a tangent to fill in unspoken parts of the story. Big Ed Magnuson and Strickland83 have done a number of great stories that flesh out the original stories.
To that end I have posted "The Train". This is my explanation of what happened between Paul and Kendall in Summer Camp Book 4 Chapter 9. I hope you enjoy it.
