In the event that you've just finished your event of The Crown Season 3, at that point Falling off the unbelievably sensational finale, which at long last gives Helena Bonham Carter's Princess Margaret the spotlight minute she'd needed all through the remainder of the period, there's one inquiry each watcher is will undoubtedly be eagerly asking: Who is Roddy Llewellyn?

Played by Harry Treadaway, Llewellyn is the tying, etch jawed chap who grabs Margaret's attention right off the bat in the finale and turns into her fleeting beau.

Llewellyn walks into Margaret's life at the perfect minute, as her turbulent union with Antony Armstrong-Jones is self-destructing.

In spite of the fact that his undertakings have for quite some time been a generally open mystery, Antony is presently truly engaged with another lady, Lucy Lindsay-Hogg (who he will proceed to wed in 1978).

Margaret isn't going to accept this profoundly pernicious disclosure without a fight, and she burns through no time in getting herself a more youthful man who—as a few characters do—looks somewhat like Antony.

Here are a couple of key realities to think about Llewellyn.

He was 17 years Margaret's lesser.

One of the numerous eyebrow-raising parts of Margaret and Llewellyn's relationship, by 1970s benchmarks, was the noteworthy age distinction between the pair. At the point when they initially met in 1973 Llewellyn was 25, while Margaret was 43.

As indicated by the BBC, he was viewed as "her most unbelievable decision to date … numerous years more youthful, footloose and extravagant free. The couple initially met in Scotland in September 1973 at the Café Royal in Edinburgh when venturing out to a local gathering in Peebleshire facilitated by Margaret's old companion, Colin Tennant."

His association with Margaret was outed by a newspaper.

As portrayed in the show, Margaret and Llewellyn's relationship becomes open when a paparazzi picture taker tails them in the midst of a get-away toward the West Indies and takes clandestine photos of the pair skipping in the sea.

For Crown enthusiasts, this minute plays as a callback to the scene of Season 2 wherein Margaret and Antony initially meet.

In the wake of consenting to give Antony a chance to photograph her, Margaret convinced him to send one of the insufficiently clad pictures to a paper, where its distribution started a minor embarrassment.

Following the distribution of the photographs, all things considered, Llewellyn gave a shamefaced articulation, stating, "I much lament any humiliation caused to Her Majesty the Queen and the illustrious family, for whom I wish to express the best regard, deference, and steadfastness. [… ] Could we please make a special effort to be allowed by the media, who have assaulted us, to continue with our work and private lives moving forward without any more impedance."

He counseled with Helena Bonham Carter for The Crown.

It's broadly realized that while some illustrious relatives watch The Crown, some determinedly don't. Yet, Llewellyn appears to have given the creation of his approval, and he even met with Bonham Carter preceding taping.

"He came to tea with me and Harry, who plays Roddy," Bonham Carter told the Sunday Times before proceeding to talk about the reasons why Llewellyn had been such a decent counterpart for Margaret.

"He was so fun and warm—that is the thing that [Margaret] required. He's melodic. He began singing a tune in my kitchen. He said they found each other exactly at the opportune time. They were both lost, both felt to some degree outcasts, just not exactly acknowledged by the family—or not exactly sufficient. Her certainty was truly undermined by the breakdown of her marriage. He additionally gave her enjoyment when she wasn't having a lot."

His association with Margaret went on for quite a while.

In spite of the fact that The Crown portrays their relationship as a generally short excursion, which apparently finishes in the season finale, in all actuality, Llewellyn and Margaret dated for a long time, as per the BBC.

In a 2002 piece for the now-ancient News of the World paper, Llewellyn opened up about his time with the princess.

"I didn't consider the results of such a prominent issue," he stated, per The Telegraph.

"I was simply following my heart. [… ] I found a warm and clever lady, having a solid feeling of obligation and commitment to her nation's advantages, who have respected me with her companionship since that first local gathering that was so loaded up with fun and giggling. [… ] In Princess Margaret I found a fine companion who could relentless my eager nature and offer insightful direction."

The sovereign endorsed of Margaret's association with Llewellyn.

Notwithstanding the contention their sentiment drew, Margaret's sister, Queen Elizabeth II, apparently gave the couple her approval—at any rate implicitly.

Per History.com, Colin Tennant's significant other, Anne Tennant, uncovered in a 2018 narrative that the sovereign moved toward her at Margaret's memorial service in 2002, and stated, "I'd recently prefer to state, Anne, it was fairly troublesome at minutes, yet I thank you such a great amount for acquainting Princess Margaret with Roddy 'cause he made her extremely cheerful."
