My AU: In my au, Leo and Raph almost always fight. They never knew Mikey and Donnie were there with them most of the time. Those to were always so caught up in their own little world of competition, they never even noticed Mikey crying at their yelling. Donnie would always bring Mikey into a hug because he didn't know what else to do, especially since Mikey has sensitive hearing. He could always hear them no matter how hard he tried to block them out.
