When a worldwide pandemic was announced, Williams and a few of her pals decided to move to Paris for the time being.
Only when the borders reopened that "we decided to come and quarantine in here for a time," Williams jokingly says.
It's a bit weird to hear her talk about her life experiences.
Even at her young age, Williams has grown accustomed to being in the spotlight.
She began acting at the age of 12 but was thrust into the limelight when the first season of "Game of Thrones" aired on HBO.
The show's eight-year run made it a global hit, and its characters became cultural icons.
No one was more courageous than Maisie Williams, who played the feisty youngest daughter of the Stark family.
Under intense public scrutiny as an adolescent, Williams had to build her image and established a sense of who she was.
The actress grew up on castle sets and fled adversaries on horseback: "Socially, maybe I found it rather hard," she says of coming of age.
"However, I've never truly known anything else."
Her age may have worked in her favor in several respects.
She may have been too naïve to be rattled or to have feelings of inadequacy.
In her "showing-off" phase, "I just wanted to perform for everybody who would watch me," she recalls.
We have changed; we are no longer so self-centered.
A decade working on a massive production like "Game of Thrones" has affected Williams's perspective on life in a profound way.
As early as kindergarten, I was taught the value of hard work and dedication and the importance of making sacrifices to achieve your dreams.
"I'm grateful for that," I said.
Her self-assuredness and maturity belied her tender years.
Williams, a 22-year-old Emmy-nominated actress, entrepreneur, and activist is now a household name.
Taking a break from probably the world's biggest pop culture franchises, Rahne Sinclair, or Wolfsbane, joins the X-Men film series' last installment, "The New Mutants," as Rahne Sinclair, or Wolfsbane, the Marvel character.
For Williams, it means stepping out of her comfort zone to see if her acting chops are up to the task of starring in a Marvel film.
People-watching is Williams' secret weapon when it comes to playing a variety of personas.
It's one of my favorite hobbies to observe people since I find them fascinating.
Walking down the street or sitting in a cafe.
What is it about a person's body language that says something about them as they enter the room?
Williams has resorted to TikTok, a major social media network, for entertainment, these days, as orders for stay-at-home moms are at an all-time high.
Because you get to watch the lives of teens from all over the world who are so unlike yourself, I find TikTok to be quite fascinating.
Despite being 22, I still play teenagers a lot, so I've been paying attention," the diminutive actress explains.
Williams' career trajectory thus far has been defined by this mix of effortless confidence and inquisitiveness, as she grows from a youngster with virtually no experience into a feisty mutant.
For Williams, the best part of her profession is the opportunity to keep learning and growing.
I still want to find others who are like me," she admits.
Williams was just named a Pasha de Cartier ambassador by French luxury brand Cartier (the other four being Academy Award-winner Rami Malek, singer Troye Sivan, singer Willow Smith, and South Korea-based artist Jackson Wang).
They are successful because of their diversity, their ability to connect with others, their ability to work in multiple disciplines, and their generosity," says Cartier International marketing and communications director Arnaud Carrez.
As Williams puts it, "I'm really proud to be affiliated with them."
Despite belonging to various social groups, each of these people represents some of the most influential voices of their period.
Even in a world where everyone can become instantaneously famous, hard effort and skill will last a lifetime.
Williams has become a household name with more than 11 million Instagram followers, despite her worries about stardom.
Even yet, she is focusing on using this as an opportunity to give back.
Integrating her spiritual advancement with rationality as well as a deep sense of community is what Williams is doing now as she mentions the Japanese concept ikigai (meaning value and purpose).
Having a voice for the voiceless, like animals, the environment, and the living world that we are constantly exploiting, is something she feels strongly about.
Because of this, Williams has been involved in several projects, including the Dolphin Project with Harry Styles for the #DontGoToSeaWorldCampaign and English magazine Dazed's "A Future World" campaign contributing her voice to causes she believes in.
A few months earlier, Williams contributed £50,000 to the Bristol Animal Rescue Centre, which had lost all of its income due to the pandemic.
And that's just one of the many organizations she has helped us a child celebrity.
Doing the right thing is difficult in today's world.
Williams is acutely conscious of her status and station in life at 22.
Because of this, she relies on the brands she's associated with to help her see the world more clearly.
As a result of Cartier's continued efforts to empower women and entrepreneurs, commit to being a socially and ethically responsible company, as well as creating items that cater to both men and women, "I think Cartier is a brand that has embraced that," she explains.
The Pasha watch, she says, is "something I identify with and feel very empowered wearing," she says. "It's amazing that I get to share something like it with men and women since I've always considered gender as quite flexible."
The new Pasha de Cartier is an exact copy of the original from the 1980s.
Cartier purposefully created a watch with a round casing and a square minute track.
Using this and similar campaigns, Williams sees herself as a true artist who has yet to be noticed by the public, as she continues to build her talent and weight outside the boundaries of her work.
Something as simple as a watch is critical because she spends much of her working day clothed in someone else's clothes.
Her thoughts are centered once again when she puts her watch back on, her jewelry, and her clothes back on at the end of each workday.
To put it another way, "I feel like I'm back in my own life."
When we're done talking, it's clear that I'm not talking to a famous person, but rather an up-and-coming artist with a childlike sense of wonder and optimism.
She explains that people have a strong desire to change the world.
That's a significant statement, but I'm confident that we can accomplish it.
