CASSIE!! Cissie loves Cassie dearly. She still carries some baggage about how things went when she quit YJ and how left behind she felt for the last several years (or however long it's been, oh timing), but she's slowly getting past them. She does have some jealousy issues where Cassie's other friends are concerned, but she knows better and represses as best she can. ;) Sometimes she worries that she doesn't "count" because she quit, but that's not a strictly Cassie issue. She doesn't always understand Cassie, but she's trying, and she thinks it is okay that she doesn't understand, if she accepts and tries anyway. She wants Cassie to be happy, and to know that she is always there for her, and she loves her no matter what.

Also, this video. Which is applicable because even when Cassie makes mistakes or does things Cissie doesn't understand, she still wants to defend her, be there for her and have her around, because she is her family.
