Shy Girl
Sydney was shy of showing off her neck rings to others. One time she lived in Maryland, she wore heavy turtleneck sweaters just to cover them up. She also worked behind the scenes to prevent any unnecessary attention.
The Mastermind
Her rings were made by her friend. They also soldered around her neck, but this features a special screw so it can be removed in case of medical emergencies. Yet she wants them to be permanently attached to her.
