Hosie is the femslash ship between Josie Saltzman and Hope Mikaelson from the Legacies fandom.

Canon
At the beginning of the show Hope and Josie are not close despite having known each other for years. However, throughout the show they grow closer and consider each other close friends. When everyone loses their memories of Hope there is some tension between the two as Josie begins a relationship with Landon in Hope's absence. However, the two eventually resume their friendship after Josie returns everyone's Malivore memories.

In "This is the Part Where You Run" Hope witnesses Josie setting her ex-girlfriend Penelope's hair on fire. Using this information she gets Josie to help her perform a dark magic spell in order to find Landon.

In "We're Being Punked, Pedro" the Salvatore School students are doing community service as a punishment for breaking out into a fight in the previous episode. Josie chooses to join Hope in picking trash. During this they argue a bit but eventually begin to bond. Later on in the episode, Josie helps Hope defeat the Gargoyle.

In "Mombie Dearest" Josie finds a letter from Hope wishing her a happy birthday, including a talisman which Josie decides to wear. Hope later helps find Josie after she was buried alive. When Josie asks what the talisman was supposed to do, Hope responds with "make quiet things heard".

In "There's a World Where Your Dreams Came True" Lizzie encounters a jinnie and is granted multiple wishes. One of her wishes takes her into an alternative universe where the Salvatore Boarding School doesn't exist and twins attend Mystic Falls High. Alaric is recruited by this universe's version of Hope Mikaelson to become the new headmaster for her father's school. While touring the school, Lizzie sees AU Josie and Hope flirting.

In "There's a Mummy on Main Street" it is revealed that Josie lied to Lizzie when they were kids and told her that Hope was spreading rumors about her. Josie says that Lizzie had made a remark about Josie being obsessed with Hope, so she lied. When asked why she did that, Josie reveals that she had a crush on Hope and didn't want Lizzie finding out. She also reveals she accidentally lit Hope's room on fire while trying to burn a love note she had slipped under Hope's door.

In "That's Nothing I Had to Remember" Hope tells Lizzie that she had a crush on Josie for a week when they were fourteen.

In "Facing Darkness is Kinda My Thing" Hope goes inside of Josie's subconscious in order to help bring her back from the dark magic inside of her. Josie's subconscious takes the form of a fairytale where Josie, the queen of the fairytale is asleep. Upon finding a sleeping Josie, Hope's pig compnion suggests she kisses Josie in order to wake her up. Hope declines, saying a "nonconsensual kiss is never the answer". It is later revealed Josie was the pig.
