We always knew there was a reason that Pedro Pascal was one of the internet’s favorite boyfriends. He has always radiated an energy of warmth and kindness–turns out he also walks the walk.

On Tuesday, Pedro Pascal took to Instagram to support his sister, Lux Pascal, who recently came out as a trans woman.

On his Instagram page, Pascal shared a picture of his sister on the cover of Spanish-language Chilean magazine, Ya. The caption read: “Mi hermana, mi corazón, nuestra Lux.”

In an interview with Ya magazine, Lux Pascal opened up about how supportive Pedro has been of her transition.

Lux explained that Pedro “has been an important part of [my transition].” Lux, who is currently studying acting at Juilliard, says that Pedro was able to be a “guide” to her because of his artistic spirit.

“He’s also an artist and has served as a guide for me,” she said. “He was one of the first people to gift me the tools that started shaping my identity.”

But her brother wasn’t the only one that was very accepting of her decision to transition. Lux explained that her transition has been “been something that’s very natural for everyone” in her family.

And like many folks who are gender non-conforming, her family seemed to have known ahead of time. “It’s almost something that they expected to happen,” she said.

Lux revealed to Ya that, for a number of years, she identified as non-binary. But she eventually realized that she actually identifies as a woman.

“Moving through the world as a woman is much more simple for me, but I still advocate for nonbinary identities to have a space in society,” she explained. While she says that existing as a woman was the right decision for her, she still “advocates for nonbinary identities to have a space in society.”

Lux is also passionate about LGBTQ activism, saying that the world needs trans activists who are good, smart, informed, and who can be strong voices against transphobia, homophobia and racism.”

When asked if she feels discomfort at seeing images of herself before her transition, Lux said, “I don’t feel anxiety when I see old photos of mine. The same happens to me with theater: I see someone who was doing what they liked.”

As for her new name (she was previously known by the name “Lucas”), Lux said she didn’t want to lose the meaning of her old name, which meant “he who brings the light.”

She looked to one of her favorite movies for inspiration. “One of the characters in Sofia Coppola’s ‘Virgin Suicides’ was named ‘Lux’ which is light in Latin,” she said. “I was pleased with my childhood memory and that my previous name had signified something I was looking for myself.”
