Prince Harry and Prince William reunited at Monday's funeral for their grandmother, Queen Elizabeth II, limiting their interactions with each other as they mourned the late monarch at St. George's Chapel.Though the brothers are said to be estranged following Harry and Meghan Markle's decision in 2020 to step down as senior members of the royal family, the pair was seen marking a show of unity during key moments at the funeral — from William inviting Harry and Meghan to sit with them at the committal service to the brothers walking alongside each other during the funeral procession.«What I didn't see was them together other than in the procession, and if you looked at the seating plan, it almost seemed like every effort was being made so that there wasn't an awkward moment where they had to sit side by side,» royal expert Katie Nicholl told ET's Kevin Frazier at Methodist Central Hall Westminster in England of William and Harry's interactions.
