Pedro Pascal celebrates sister Lux after she comes out as a trans woman: 'Mi hermana, mi corazón'

While fans know and love Pedro Pascal for his memorable performances in big franchises of the likes of The Mandalorian, Game of Thrones, and Wonder Woman 1984, the one role he takes most seriously is his real-life role as a big brother. The 45-year-old recently proved himself to be his sister Lux's biggest cheerleader when he proudly introduced her to the world after she publicly came out as a trans woman. Sharing a photo of Lux's cover debut for the Chilean magazine Ya with his 2.1 million Instagram followers, Pascal wrote: "Mi hermana, mi corazón, nuestra Lux." The heartwarming caption translates to, "my sister, my heart, our Lux."

According to PEOPLE, Lux opened up about her transition for the first time in a cover story for Ya, where she revealed that she started receiving hormone treatment in July last year. The 28-year-old, who has appeared in Chilean dramas Los 80 and La Jauría, is now studying acting at the prestigious Juilliard School in New York City. "My transition has been something that's very natural for everyone in my family," Lux said in the interview, translated from her native Spanish. "It's almost something that they expected to happen."

Lux credited her big brother as an "important part" of her transition as she recalled coming out to Pascal over the phone. "[He] has been an important part of this. He's also an artist and has served as a guide for me. He was one of the first people to gift me the tools that started shaping my identity," she said. "When I officially told him about my transition through Facetime, he asked me how I felt… because I remember that he was worried. I told him: 'I'm happy.' And his answer was: 'Perfect, this is incredible.'" Lux also revealed that she had earlier told her family that she was nonbinary, but realized that "moving through the world as a woman is much more simple for" her. "But I still advocate for non-binary identities to have a space in society," she added.

According to Remezcla, Lux explained in the interview that she shies away from becoming a voice for the trans rights movement as she feels that she has been lucky to have been in a position of privilege during her transition. "I have had a certain form of privilege because I have been able to make my transition hidden and with support," she said. "LGBTQ+ equality movement has been led by the most marginalized of voices, those who at the end of the day, had nothing to lose because they had already been deprived [of] everything. I have been very fortunate."

Instead, Lux plans to use her platform and the public spotlight to highlight trans voices — something she feels is her duty as a privileged trans woman. "I feel that many will say that I am appropriating the discourse of unprivileged trans women, trans sex workers, or trans people who do not have the money or the help to buy their hormones or transition as they want. But I have a connection with them. I call them sisters because I feel them like that," she said. "We need trans activists who are good, smart, informed, and who can be strong voices against transphobia, homophobia, and racism."
