Morgana at Mordred's grave. I actually thought that this was really sad. In the midst of her bitterness and obsession with revenge, she pauses to bury the only person left who cared about her. It's morning, meaning it took all night for her to drag Mordred from the battlefield by herself and find a proper spot to bury him. She felt that he loved her as she loved him. So to lose the one person who loved her--knowing that it was probably her fault her died--must have cut deep.
