Hosts James and Oliver Phelps meet the remaining six teams in front of the Knight Bus and challenge them to create showpieces inspired by magical transportation from the Harry Potter world that give the illusion of movement. Plus, the bakers are assigned classic English desserts that must be incorporated into their tasting elements. Special guest Devon Murray, who played Seamus Finnigan in the Harry Potter films, surprises the competitors and joins Judges Carla Hall and Jozef Youssef in deciding which team will be sent home.
