Royal expert Katie Nicholl reveals to ET that Prince William has definitely been affected by his brother, Prince Harry's, bombshell Oprah Winfrey interview alongside his wife, Megan Markle, that aired on Sunday on CBS. Harry made shocking comments about his family, including that he felt Will and their father, Prince Charles, were "trapped" in the royal institution. Megan also claimed that Will's wife, Kate Middleton, made her cry around the time of her wedding to Harry, though Kate later apologized and gave her flowers.
