   Summary

   A collection of whatever I feel the desire to write at that time regarding ZZZ! This shit grabbed me by the scruff and right now it's not letting me go. More characters may be written just depending. I don't take requests, but feel free to leave suggestions or ideas in the comments. Oh yeah, this'll mostly be Billy. I fucking love Billy. I need more writers to write about Billy. I will not promise to not go on another writing hiatus because the motivation to write comes and goes and I can't control how long it stays!!! Sorry in advance!!!!!!!!!!!
