Will Ruby ever take off her key necklace?

I don't think that Ruby will ever be able to take off her necklace. The key on her necklace was the key to her old house that she lived in with her mother. To her this key symbolizes her past which was very important to her. Her past wasn't the best but she learned from it and it helped her. Most people would want to forget their pasts but Ruby didn't. She thought of the necklace as a key into her past which she would always keep because it really changed her.
