Pin-Lee (Sabrina Wu) is one of the supporting characters in the AppleTV+ sci-fi action-comedy series, Murderbot (2025). The series is adapted for the screen from the saga The Murderbot Diaries, written by Martha Wells. Both Wu and Pin-Lee are nonbinary and use the pronouns they/them.
Pin-Lee is a scientist and counsel for a science team from the Preservation Alliance, sent on a scientific mission to explore an untapped planet in the Corporation Rim. They are alarmed not only at both the discovery of certain variables on the planet and suspicious activity, but at the fact that their security cyborg (Alexander Skarsgård in the title role) has overridden its government software and seems to have established sentience.
Pin-Lee is in a committed partnership with Arada (Tatiawna Jones), a biologist who is also on the mission. Pin-Lee is brilliant, caring, and cares deeply about their team, which closely resembles a chosen or found family as a collective. They semi-reluctantly agree to open their relationship to take on a third partner, Ratthi (Akshay Khanna), a wormhole expert and another scientist on the mission. At first this seems to be mostly to appease their partner, though they find Ratthi attractive enough. But as the series moves on, it becomes clear that Ratthi, who initially was mostly interested in Arada, has fallen for Pin-Lee. Pin-Lee feels more emotional attraction towards Ratthi than at the beginning of the series and feels some conflict with the balance of the triad. The throuple eventually dissolves amicably due to the imbalance of the feelings and attractions of the three partners, seemingly without much emotional aftermath.
What is particularly interesting about Murderbot, is that in this world bisexuality is not only accepted, but normalized along with alternative relationship structures to the point that the triad can bring up and sign a boilerplate contract honoring their three-way agreement. It is also particularly noteworthy that, though these relationships are important to Pin-Lee, they are not the center of their arc or character traits, but are treated as part of their character instead of the whole.
