She came to her brother's birthday party that was organized by his daughter, Emma, with her mother. Right after Emma was struck with the moonlight, Emma made a joke about her skirt looking like a picnic rug, the joke made everyone laugh. Thea also saw Emma outside when she looked for her, but the other girls scared her back inside with bat stories. Seeing the party falling apart, Thea thought that Emma is a rather tasteless human. Thea interrupted Emma and Byron from kissing right before the dinner. Then she suggested to Emma's parents that she needs some good old-fashioned discipline.
