I am currently working a two-part fanfiction story for this particular fandom. However, the first part of this story doesn't involve our favorite ghost-busting boys (that will come later). Instead I thought to take it upon myself to give a background story for two ghosts that only had a few minutes of screen time. The Scoleri Brothers.
Their own cannon background was very short and didn't offer much (which was a total pain for me since I tried to get their personalities right >_< ). The only thing I know about from the creators is that they were sentenced to the electric chair at Sing Sing maximum security prison in 1948 by Judge Wexler for murder.
So. I broadened it. I'll release a short bio on them tomorrow, maybe with chapter one of the first part but that might not happen. Still have a few kinks in the story that I have to work out.
