Petalia Duet was one of the slave medic’s for Jarl Jaeger Thorsson’s pirate squadron. She goes by “Two,” a nickname given to her by Tyrian Tauri, the pirate king. She healed Ceres, with Serenity’s help, after he got shot in a duel. She also crafted some meds to help him resist Ka’ra’s chemical charms during the recon and escape phases of the Valhalla Op.
