Stuck! The Siamese Twin Nightmare

Jewels has a problem. She faces prison every day. But Jewels is innocent. She has committed no crime. She is not being punished. 

You might say that she has a monkey on her back. Literally. Or should I say a fat-head who constantly tells her what to do, how to act, and what to believe in. For you see, Jewels has a Siamese twin sister who they both share one body. But only recently, Jewels' sister, Nora, does not want to live with Jewels any longer. In fact, she wants a way to do away with her. But how, since they do share only ONE body?
