"Improve the bloodlines." Diana is a distant cousin of Charles. It was all hyped for the Royals. He needed to have spoke up and stuck with Camilla but by then, she'd 'stolen' Princess Anne's beau and married him.

But yes, she was his mate all along.

Diana was rumored to have given birth to a child to prove she was fertile before hand. That could just be idle gossip. How sad if it was real. She was the loser in all of it.
