While looking for two disappeared anthropologists, Lewis and Tom, a ground team from the Orville enters a coffee shop. The barista, Lysella, flirts with John before his Vote Badge receives hundreds of thousands of downvotes. Shocked, she ejects the entire team from the shop.
Later, Chief of Security Alara Kitan and Doctor Claire Finn find Lysella in the coffee shop in the hopes that she can lead them to the Sargun government's "base of operations." Before they can speak, however, Alara is accosted by Kelvic man who is angry with her for wearing a traditional Kelvic headpiece. Alara and Claire retreat to the shop's restroom. Lysella enters to tell them the man has left and sees that Alara is not Sargun.
Alara and Claire explain to Lysella that they, along with John, are from another world, and need to rescue him. Lysella is shuttled to the Orville's ship, where she is introduced to Captain Ed Mercer, Second Officer Bortus, and Science Officer Isaac, and in return she explains how the world's voting system works. She assists Isaac in uploading manipulative, fake videos of John to the Master Feed in order to change public opinion of him, suggesting what would make LaMarr an appealing figure on short notice.
Once LaMarr is released, Lysella is returned to her world. She decides no longer to vote in the Master Feed.
Lysella is outgoing: she enjoys parties and socializing with her cadre of friends. Based on the state of her quarters, she is neat and orderly. After discovering the alien origin of Claire and Alara, she quickly finishes a presumably alcoholic beverage in moments.
Lysella is portrayed as a typical Sargun, blithely unaware that their voting system permanently damages individuals based solely on public disapproval. At the start of the episode, she uses upvotes and downvotes liberally to punish or reward people for qualities she likes. For example, Lysella vows to downvote a woman named Jesala who did not return a borrowed, unidentified item, and quickly upvotes LaMarr based on his attractive appearance alone. However, by the episode's end she no longer participates in the voting system, having grown as a character.
