Ron, Hermione, and Harry Conjure a Dark Mark Above London
On Friday, the Duke and Duchess of Cambridge took Little Brother of the World, Prince Harry, on a trip to Warner Bros. Studios for the new Making of "Harry Potter" tour. According to People, while there, William shouted "Expelliarmus!" at a group of children also brandishing fake wands. It's unclear why he felt it necessary to disarm them.
