Despite the tension between Meghan and Kate, Harry and Kate shared a close relationship. Kate had a nickname from Harry, “Cath,” showing their bond. Kate once said, “We did become very close friends from quite early on.”

Although William and Harry’s relationship has since soured, royal biographer Christopher Andersen believes Kate could help reunite the brothers. “Of course, Kate would love nothing more than to see the brothers kiss and make up,” he said, but she’s also loyal to her husband, William, and understands his reasons for remaining upset.
