Cassie was friends with Lori, a fellow animator. They bought expensive special pencils and promised to use them only for special projects and to ask each other first. However, both of them did use the pencils quite a bit.
When Neflite took control of Lori, Cassie told Amy Anderson she believed something was wrong with her friend. When she, Amy, Raye Hino, and Serena Tsukino went to confront Lori, Cassie fainted when the Gemini Warriors appeared, which allowed Serena, Amy, and Raye to transform without exposing their secret.
When Lori's energy was restored and the Gemini Warriors were destroyed, she and Lori discussed the fact that Lori used the special pencils they bought together. Cassie held no hard feelings toward her friend and promised that they would remain friends.
