Hayley is the mother of Freya's niece Hope through her half brother Klaus. Hayley has saved Freya's life by giving her blood to heal a wound. Freya helped Klaus look after Hayley's daughter Hope while Hayley was under the Crescent Curse placed on her by Dahlia.
Throughout The Originals SeriesEdit
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.
