Klaus and Aurora began their relationship some time after the Mikaelson Family came to the Count de Martel's castle. Soon after, Aurora caught the eye of Klaus and they slowly fell in love. Their relationship became more complex in modern days, as they haven't seen each other in centuries. They had a temporary sexual relationship before Aurora started threatening Camille O'Connell.
Aurora currently desires revenge against the entire Mikaelson family, especially Klaus, who chose Camille over her. However, Klaus counterattacked her revenge plot and walled her in to the Garden where vampires are forced to desiccate for a long time, or possibly eternity.
After she was released from her entombment by Lucien, Aurora and Klaus reunited once again.

Niklaus and his family disguised themselves as Nobles in order to hide in plain sight and stayed at the Count De Martel's castle. It was there that Klaus and Aurora first laid eyes on one another. Klaus remarked how Aurora was exquisite. They soon fell in love and began their secret affair.
Not long after Lucien became a vampire, Aurora soon discovered what Klaus and his family were. Regardless of this revelation, she still loved him all the same, even after he revealed that he killed his mother.

When Mikael found out the location of Klaus and his siblings, Klaus asked Aurora to run with him and his family so they could be together, but she broke his heart. Unbeknownst to him, Aurora had been inadvertently compelled by Elijah out of anger when he discovered the truth about their mother.

- Klaus: "I never meant for you to know me. I never meant to let you in. But then, I should not have kissed you. Not the first time. Certainly not the second. There is a light in you so bright it makes me feel like the man I wish I was... and forget the thing I am. I am chained to certain hungers, and have damned another to my fate...You've seen what we do-- we hunt. We feed. We kill. But what I am, I can't answer. My family are the first-- there is no name for it. But I also desire. Deeply. And I can love... As I love you."
- Aurora: "Ooh, how you loathe me, so certain I've come to do you harm. Yet, as I recall, we did plenty of harm to each other. And, if I'm not mistaken, we both rather liked it, didn't we?"
- Aurora: "Do you remember what that first time felt like, to be with someone every bit as powerful, as tormented, and as cursed as you?"
- Aurora: "Look me in the eye and tell me that you haven't thought about what we had every day for the last thousand years. You want to know why I have come? Because after a thousand years of trying to erase your touch, your smell, the taste of your lips... I'm here for you."
- Klaus:"We could have been the greatest love story ever told, perhaps you have forgotten why we are not."
- Aurora: "You know, over the long centuries, I would dream of you, My bright light in an ocean of darkness, whose despair mirrored my own, and whose love brought me a joy I had not felt, and have not felt since."
- Klaus: "Two hundred years ago, it was my art studio. It became a tomb for my memory of you.I thought that if I painted what haunted me, I could free myself of you forever. In all my years, I have never been more wrong about anything."
- Klaus: "I tire of this fantasy. You are someone I left behind long ago. And there is nothing between us now."
- Aurora: "You're angry. We say things to hurt each other when we're angry, that's what lovers do, but I know that I am the one for you. As I know that you will thank me, eventually, for killing your little human pet."
- Klaus: "You presume to know me? Then know this: I will gladly end you for what you did to Camille. But first, I'm gonna make you suffer in ways your spoiled little mind cannot possibly imagine. And when it's over, when your sweet recollections have been rendered obsolete, you will associate my name with fear and pain and perhaps the dull realization that you are nothing to me."
