While usually not very active, she becomes proactive regarding Guest. She may interpret Guest's words and actions in an exaggerated way and take eccentric actions, such as trying to wear a cheerleader costume just because Guest said they felt a bit down, or bringing a pillow and blanket just because Guest yawned.
