Harry and Oprah Winfrey's show aired on Apple TV+ today, on May 21.

Harry made a lot of revelations during the show.

But one about Archie's first words have really shaken the internet.

The prince first revealed he's undergoing treatment for PTSD.

And that requests for the royal family to help him with his mental health were met with "total silence."​

In fact, he accused the royal family of "total neglect."

And claimed he was "afraid" of returning to the UK for Prince Philip's funeral.

He also spoke out about his history of substance use.​

Which he believes began with him trying to "mask" the pain of his mother's death.

He pointed out another factor in Diana's death.

The fact she was dating "someone who wasn't white" at the time.

Over the course of the series, Harry was unusually candid about the death of his mother.

Although what he said has been very controversial to some.

"When my mum was taken away from me at the age of 12, I didn't want the [royal] life, sharing the grief of my mother's death with the world."

"For me, the thing I remember the most was the sound of the horses' hooves going along the Mall."

"It was like I was outside of my body and just walking along doing what was expected of me."

Getty

"(I was) showing one tenth of the emotion that everybody else was showing: This was my mum - you never even met her."

​He continued. 

Getty

"I was so angry with what happened to her and that there was no justice, at all. Nothing came from that."

"Unfortunately when I think about my mum, the first thing that comes to mind is always the same one over and over again."

Getty

"Strapped in the car, seat belt across with my brother in the car as well and mother driving and being chased by three, four, five mopeds with paparazzi on."

"She was always unable to drive because of the tears."

Getty

"There was no protection."

Harry also opened up about how his mom would feel about his life today.

Getty

"I've got a hell of a lot of my mum in me. I feel as though I am outside of the system - but I'm still stuck there. The only way to free yourself and break out is to tell the truth."

"I wish she could have met Meghan. I wish she was around for Archie."

He then revealed a heartbreaking detail about Archie.

​"I've got a photo up in his nursery... and it was one of the first words that he said."

"Apart from 'mama', 'papa', it was then 'grandma', 'grandma Diana'. It's the sweetest thing but at the same time makes me really sad."

The series is now available to stream.
