   Summary

   Blue was tired, he was hungry, and quite frankly, he was done with Ink and Dream and how they treated him. He knew if this went on much longer, he was going to fall down from malnutrition or exhaustion before he fell in battle. Well, none of Nightmare's followers seemed to be treated poorly, so Blue might as well join him.
   Or my take on the Blue joins the Bad Sanses, because there isn't enough, and I need more.
   I just need more Blue-centric fics, really.
   My AU is a mess, and I have decided to make it everyone's problem.
