Marbles's Links
Marbles loves her little sister very much and is very protective of her. However, she doesn't appreciate her sisters help because she doesn't think she needs help.
Marbles loves her sister and despite being the younger sister, she often needs to care for her. Marbles' intensity can be draining on Socks so she doesn't spend too much time with her.
Knight was by no means Marbles' first love, however, he was the first to accept her despite her intensity. Her attraction to him was superficial, however, as time went on she grew to love his qualities. Although due to her fear of commitment, when Knight desired to adventure further away she rashly broke things off. Which she regretted long afterward and continued to mourn their relationship.
Knight never was particularly interested in anyone and no one was ever interested in him. So he was taken off guard when Marbles expressed interest in him. He was intrigued and always up for an adventure so he accepted her proposal. They did not mesh very well and would often fight, however, Knight always put up with Marbles and truly cared for her. He was shocked and hurt when Marbles chose to break things off. He still remembers Marbles fondly after their break up, however, he is against ever getting back together with her.
