Rescuing Julia

Riley and Julia. Friends since they were toddlers, but are total opposites in personality. Julia is more girly and loves cute things, anything pink, and hanging out with Riley. Riley is dark and mysterious (maybe even mean) to other people, but to Julia, she is really friendly and sweet. She loves supernatural things, the colour black, and she hates to admit this, but enjoys spending time with Julia. These girls see each basically everyday, never leaving each other's side. So what would happen if something changed this?

IDK if some people will be triggered by this, but anyways, *TRIGGER WARNING*
