Prince Harry and his wife Meghan Markle have surprised much of the UK with their secret trip to their former homeland.
The Duke and Duchess of Sussex, who now reside in Los Angeles after quitting the UK in 2020, flew in yesterday from the US for a face-to-face with the Queen at Windsor Castle.
The couple also saw Harry's father, Prince of Wales during the quick stop on their way to Holland for the Invictus Games, writes The Mirror.
The couple, who snubbed the chance to attend the late Prince Philip's memorial service last month, smiled and waved at stunned onlookers.
They've been at the centre of a few controversies since quitting the UK, from tell-all bombshell interviews to high-profile legal cases.
It's all been extremely uncomfortable and embarrassing for the monarch and the rest of The Firm.
And their decision not to return home for big family events - including Prince Philip's memorial service two weeks ago - means there have been limited opportunities to discuss them, until now.
It's only the second time Harry has visited his family in two years.
And it's the first time Meghan has seen any of them since the couple announced they were quitting royal life.
But what might they have talked about during the short face-to-face meeting on their way to the Invictus Games in The Hague? Here we take a look at what could have been said behind closed doors...
Security issue
Harry's ongoing legal challenge against the Home Office regarding his and his family' security when he is in the UK is one of the reasons he has cited for staying away.
He is bringing the claim after being told he would no longer be given the same degree of personal protective security when visiting from the US, despite offering to pay for it himself.
The duke wants to bring his children to visit, but claims it's "too dangerous" according to a legal representative.
Still no Lilibet meeting and christening debate
Lilibet is the first daughter of the Sussexes and is named after the Queen.
It was the nickname Prince Philip used for his wife so it was an affectionate nod to the monarch despite the distance between the relatives.
But despite being born last June, the Queen is yet to meet her great-granddaughter, so there is a chance she may have asked if she will get a cuddle any time soon.
Due to her age, the Queen doesn't travel abroad any more so a meeting would involve Meghan and Harry bringing their children to the UK, which Harry has said he doesn't want to do due to the rows over security.
If his stance on this doesn't chance, the Queen may never get to meet little Lili, despite her being eighth in line to the throne.
Details of Lilibet's christening are also still to be decided, so they could have discussed that.
Many royal fans were left wondering if she will get the traditional welcome to the church.
This is very important for the royal family as the Monarch is Defender of the Faith and Supreme Governor of the Church of England.
The celebrations are normally a big family affair and official photos are usually shared with fans.
However when it came to Archie's christening, Meghan and Harry raised eyebrows by doing things their own way and cutting the public and press out. Photographers weren't invited to take pictures of guests arriving and all the details - including the Godparents - were kept secret.
But it's not known if the couple will decide to give Lilibet a traditional royal christening, and if so when it will take place.
Royal kids are normally christened quite early but Lili will be celebrating her first birthday in June.
Oprah interview - royal racist and mental health
The secret meeting was the first time Meghan has seen the Queen since she made a number of bombshell claims in her interview with Oprah Winfrey.
There is a chance the Monarch would have used the meeting to clear the air on some of the distressing issues raised, after releasing a statement saying she was "saddened to learn the full extent of how challenging" the Duchess' time in the royal spotlight had been.
Among the most shocking were her allegations that someone in the royal family asked questions about how dark Archie's skin would be. Harry later said he would never reveal which of his relatives it was, but said it wasn't the Queen or Prince Philip.
The statement caused huge upset across the world and saw Prince William questioned on whether the royal family was racist. He replied: "We are very much not a racist family."
Meghan also said she was denied help for her mental health during her time in the royal family, despite having suicidal thoughts.
She told Oprah she "didn't want to be alive anymore" and when asked directly if she was thinking of self-harm and having suicidal thoughts at some stage, Meghan replied "yes".
She says Harry "cradled her" when she told him, and he later admitted it send him to a "dark place".
Meghan claims she asked the palace to seek professional help, and said she no longer had access to personal effects such as her passport after joining the family.
However she says she was told she couldn't get help.
In the interview, Harry also accused Charles and William of being trapped and said his father had cut him off financially. Meghan accused Kate of making her cry and said she wasn't supported when she joined the royal family, saying she had to Google the words to the National Anthem.
After the interview, the Queen released an unusual statement addressing the claims.
She said: "The whole family is saddened to learn the full extent of how challenging the last few years have been for Harry and Meghan.
"The issues raised, particularly that of race, are concerning. Whilst some recollections may vary, they are taken very seriously and will be addressed by the family privately.
"Harry, Meghan and Archie will always be much loved family members."
Harry's memoir
Harry's upcoming memoir could be a major source of discussion.
He's set to give his account of life within the royal family.
This goes against the Queen's desire to keep private affairs private and could be extremely embarrassing for The Firm.
He's understood to have received a £15million advance on the book, which is due out later this year.
While it's unlikely that Harry will hit out at his grandmother in the book, many experts believe he will hold no punches when it comes to his step-mum Camilla, who earlier this year the Monarch put forward as the future Queen Consort.
Ex-Vanity Fair editor Tina Brown, who was friends with Diana, says Harry "can't stand" his father's second wife and doesn't want her to be Queen.
Why they missed Prince Philip memorial
Even though yesterday's meeting was the first time back in the UK for Meghan since leaving for America, Harry has actually been back twice.
One of those times was for the funeral for his late grandfather Prince Philip, who died aged 99 last April.
As his funeral was hit with Covid-restrictions, a huge memorial service was held at Westminster Abbey last month attended by 1,800 - including nearly all of the royals.
However, Harry and Meghan both skipped the event - with Harry in particular coming in for blunt criticism for failing to attend to honour his grandfather and support his grandmother.
Maybe the Queen and Charles broached the subject of them not coming to the UK for the event during their talks?
Rift with Prince William
One royal who was absent from the Sussex's meeting with the Queen and Charles was Harry's older brother Prince William.
There has been much made of the rift between the two brothers.
It was reportedly sparked by William's concerns over Harry's fast-developing relationship with Meghan ahead of their royal wedding in 2018.
The tense row quickly boiled over - with Harry claiming his brother was "trapped" within the royal system during the Oprah interview after quitting as a senior royal.
It's been reported that the relationship between the two brothers has still not recovered, and speaking on a documentary last year, royal expert Emily Nash said the falling out between the two brothers will be "hard" for the Queen to bear.
Might both Her Majesty and the brother's father Charles discussed Harry's rift with William - and urged him to take the first step in burying the hatchet?
