## History

### 2012

Klaus had first met sixteen-year-old Dianna while they were both attending Hayley and Jackson's wedding at his home on December 31, 2012. He didn't warm up to the young woman very quickly at first, due to the fact that she was a werewolf-witch hybrid. That had reminded Klaus of his first wife, who he lost many, many years before.

### 2013

When Alaina Olsen, Dianna's mother, had suggested that Dianna remain in New Orleans to be with her pack and so she could be around others that were like her, her cousin Hayley insists that she moves into the Mikaelson Compound. That puts her in consistent proximity to Klaus, due to the fact that Compound is his home. Klaus seemed to eventually warm up to Dianna, finally noticing that she is very, very different from his first wife. He even starts to encourage her romantic relationship with his older half-brother, Elijah, even giving his brother the money to purchase her a engagement ring. Once Dianna and Elijah became engaged, he was among the first to congratulate them on their engagement,

She also has enough respect for Klaus and his power that she advised her cousin, Hayley, against running away with her and Klaus' daughter, Hope. Despite this, Dianna late becomes a victim of the Crescent Curse that was placed Hayley and the Crescent Wolf Pack after she attempted to run away with Hope. Eventually the curse was lifted and it seems that Dianna had been made ill by the exposure. He tried to apologize for his actions but she told him that she couldn't fault a father for attempting to protect his and his daughter's relationship. She even counseled her fiancé, Elijah on reconciling with his brother by reminding him that he invoked Klaus' rage and knew his revenge would be biblical.

When Klaus attempts to defend Elijah's attending the Strix party with Hayley without telling Dianna, Dianna thinks he is simply honoring the code to smooth things over for his brother and tells him to save his breath before snapping his neck. This strains their relationship for a number of days after she returns to the Compound.

Klaus is seen being bossed around by the 17 year old while she decorates his home for Christmas. He states that she is lucky she is a sister to him or he would not tolerate such behavior in his home. She responds that hardly a year ago he despised her and that now he was calling her a sister. He laughs and says that anyone who makes his brother so happy was a welcome addition to the family. He later gives her the keys to a new luxury car as a Christmas gift.

When she is killed for the first time and her heart is sent to the Compound in a box, Klaus vows revenge on the family responsible. He later encourages her to complete the transition, reassuring her that being a Werewolf-Vampire Hybrid as she was thought to become was not so awful. He later helps keep her from attacking her sister when she falls into her bloodlust immediately after becoming a vampire, and is shocked to find that her ability to use magic has remained.

He is later best man at her wedding to his brother and welcomes her officially to the family in his toast. He also helps keep her safe by keeping her survival a secret from the rest of the world who may have targeted her due to her unique nature.

### 2014

**Niklaus**: "*So you don't wanna talk, fine I shall do the talking. I will tell you what I know from personal experience little werewitch. I wish I could tell you that the feelings of loneliness and isolation that you feel will go away or that the painful ache you feel in your heart when you realize that you're painfully difference from those around you will ever go away. But then I would be lying to you, what I can tell you is that you will learn to live and even thrive with them. I certainly have.*"

**Dianna**: "*I'm not as strong as you are, Klaus! I just drown in these feelings and I can't do this anymore. I though I could, but I just can't!*"

**Niklaus**: "*I didn't think I could do it when I first turned either, sometimes I still think I can't. It is surviving in spite of that, that shows your true strength.*"
— **Klaus** and **Dianna** having a discussion about being the first of their kind
Klaus helped Dianna learn how to adjust to being the first of her kind, as he had been the first of his kind at well. She later attempted to help rescue him from the Strix Coven when they captured him and Elijah and attempted to help prevent them from completing the desiring spell. When they were unfortunately successful she helped him disappear so that he and his daughter could be safe from legions of enemies that had came to attempt to kill him.

She hugged him when he returned home after Finn was bitten. She later helped deliver his second daughter and recognizing that he was in an emotional state that made him ill prepared to take care of his premature daughter and cared for her for him.

She later helped him when he took down Lucien by helping hold Lucien down for Freya to perform the Reversal Spell on his Upgraded Original Vampire nature. She attempted to convince him to forgive Elijah after he murdered Marcel.

Klaus later entrusts his younger daughter to Dianna's care. When he is stabbed with Papa Tunde's Blade she attempted to try to steal his body back before he was bricked up but failed in her attempt.

### 2019

She assisted in his rescue from Marcel's dungeon. She helped her husband support Klaus' body weight as they travelled through the tunnels and drainage pipes back to the rest of his family. She also showed him pictures of his younger daughter on her phone, and he thanked her for all of her care. She gave him bloodbags.
