The next cause she wanted to take on was illiteracy. She also desperately wanted more children. I can imagine her bringing back a child from one of her Africa trips. I think she would have had a flat in New York and maybe a place in L.A.... The man in her life? As she got older, I think she would want someone who could take care of her and protect her from the press and basically wrap her around with a security blanket.

Diana's former private secretary

Having got their extramarital experimentation out of their systems, she and [Charles] ... could have reached a pragmatic reconciliation.

She would have retired to a convent. The only guests she would receive would be her sons. To be more serious, she always had a spiritual side. She would have turned her back on the world because the alternative was craziness. She would be single and chaste. She'd had enough with worthless men.

Ken Wharfe
Diana's former bodyguard

She would have campaigned for Darfur. She would have needed someone stable—not a rock star or multimillionaire American.

Simone Simmons
Diana's natural healer and confidante

She would have hated it if William and Harry were close to Camilla. Their upbringing would have been different. She would have emphasized a bit of restraint.

Christopher Andersen
author, After Diana

She'd be single and loving it, but dating the likes of [New York City mayor] Michael Bloomberg—money, power, she loved Americans. And she would have pushed for Kate Middleton. Diana would have recognized a great soulmate for William.
