The End of the World

Mabel is a regular school girl who is bullied horrendously. Dipper is Mabel's long lost twin brother who is being experimented on in a top secret science lab. Watch as they both see their worlds end around them, and as they try to save everything and see each other one last time. Rated T for abuse, language, suicidal thoughts, and possible character death. No ships. A little OOC
