I saw that in the comment section to my previous chapter, there were a few confused people who didn't really know what I meant by 'the demon in Jimmy's head', and that's ok! Here's the explanation:
So we all know that Ghost has Jimmy in his head, and that he's been there since at least high school. Everyone got that. The problem is with Jimmy. I'm not going to reveal anything to super important about Jimmy's past quite yet. All i'm going to say is that the demon has been in his head since he was around 10 years old. The demon has caused lots of problems, and influences Jimmy's decisions greatly (especially who he murders and who he doesn't). Sometimes, the demon will stay quiet for a long period of time, causing Jimmy to forget it was there. The demon was not always in his head though. That's all I have to say! ;)
Hope this helped!
