Cordelia wanted to make an impression when she entered her sorceress ball, with Cedric helping her by using a potion spell that would create smoke, but Cordelia accidentally mixed in another potion without them both realising it. When Cedric used the potion on Cordelia it caused her hair to turn short, spiky, and gray. Cedric tried to help, but just turned it green. She blamed Cedric into adulthood.
Cordelia and Calista had to stay at for a while until their own castle's renovations had been finished. Cordelia and Cedric got into a fight over how to make Sofia's melon smaller, but they accidentally shrunk the castle and everything in it. In the meantime, Sofia and Calista desperately found out the truth of Cordelia's accident with the Looking Back Glass, which they then showed the siblings. Cedric then made everything regular size again, followed by restoring Cordelia's hair (now knowing the correct counter spell to use), which finally put a rest to their rivalry.
