Throughout The Originals Series
Hayley met Freya either in or before Night Has A Thousand Eyes. Freya was at the compound discussing how best to prevent people being possessed by Dahlia, like Hayley's husband Jackson Kenner had just experienced. Freya created a tonic in order to prevent it happening again which Hayley consumed with the rest of the Mikaelson's.
Freya suggested using Jackson as a way to find Dahlia, Hayley wasn't happy with the idea at first, but after silent persuasion from Klaus she relented and agreed to let Freya perform the spell.
Later on in the episode, Hayley pushes Freya away from Jackson as she is performing a spell on him, as Rebekah believed Freya was being used by Dahlia as a power source and was a danger.
In For the Next Millennium, it is revealed in the voiceover for the episode, which narrates a letter Freya is writing to Rebekah, that Freya has been working on a way to break the curse that binds Hayley to only becoming a human on the full moon and Klaus has been no help with that, and she know's Hayley is struggling with only seeing Hope once a month. Freya also states that her brothers are at odds because Klaus will not apologize to Elijah for "the suffering Hayley continues to endure" in reference to the curse Klaus had Dahlia place on Hayley. Freya, along with her brothers Elijah and Klaus has been looking after the latter's child with Hayley, Hope. In the same voiceover, she mentions that it is clear that Hope misses Hayley.
In You Hung the Moon, Klaus asks Freya to perform a locating spell to find the missing Hayley. Freya obliges, though she cannot find Hayley through the spell, unknown to her this is because of Davina Claire's magic cloaking her.
Later on, in the episode, Hayley knocks Freya out as she is examining Jackson for the Crescent Curse. While Hayley and Klaus fight, Freya uses magic to prevent Jackson going to Hayley as she knows Klaus will hurt Jackson. Freya looks on as Hayley reconciles with her daughter and tells Klaus she is moving out.
In Out of the Easy,
In The Bloody Crown, Hayley and Freya work together to save Kol and Elijah as Klaus confronts Marcel and the rest of the Original hybrid's former sireline. Klaus decides to sacrifice himself to Papa Tunde's blade as Freya spells the rest of their siblings to a purgatory-like slumber. Freya does this and Hayley ensures them all that she will find a cure for all the Mikaelson siblings as they slumber and wait for Hayley to find a cure.
In Gather Up the Killers, After five years, Hayley prepares to wake Freya up early from the Chambre de Chasse. After gathering, the final ingredient needed, she stabs a syringe into Freya’s heart causing her to awaken, and Hayley happily embraces Freya. The pair then continued the preparations needed to awaken and cure the rest of the Mikaelson's. The warehouse is soon attacked by vampires, and Freya tells Hayley that they need more time, prompting Hayley to attack the vampires and fend them off.
In Haunter of Ruins, Hayley and Freya fight over allowing Keelin to be set free. Hayley pins her against a wall and Freya telekinetically throws Hayley a few meters back. The two continue to fight, before arguing. Freya starts to say something about Hayley not being family, but Elijah stops her and Freya leaves after Elijah sides with Hayley, and tells Freya not to look for Keelin.
In A Spirit Here That Won't Be Broken, Freya informs Hayley and Klaus that Elijah is running out of time in her pendant, and that they need to kill the Hollow to create a surge of power to bring Elijah back. Freya also tells them that Hayley's blood isn't strong enough to kill the Hollow, as she's techincially been dead for years. However, Hope's blood would be potent enough. Klaus and Hayley orignally tell Freya no, but Hayley eventually agrees. Freya and Hayley then team-up to find and destroy the Hollow at the LaForge house, where she's hidden herself. Before going into the house, Freya confides in Hayley about how she is worried about not coming home from the fight now that she has Keelin to come home to. Hayley then tells Freya that she will come home, and that she has her back. Freya tells Hayley that they haven't always seen eye-to-eye, but family rarely does. This is the first time Freya calls Hayley family. Later, Freya subdues the Hollow enough for Hayley to kill her. When Hayley is killing the Hollow, she gets swept up in the moment and starts repeatedly stabbing her. Freya then pulls Hayley off of her dead body and states that she is dead and that Hayley did it.
