When Karyn made her wish, the person standing closest to her was Athena, obviously, since she was the one pulling her away from Jon. And, because this was the Mimicry Stone, she acquired 10% of Athena's personality, which was her taste in gothic clothing. Now Karyn's personality was 60% her own, 10% Sarah, 10% Kyla, 10% Zoe, and 10% Athena. She was definitely starting to lose her identity.
