In The Originals series finale, Klaus makes up for 1,000 years of torturing Rebekah by offering her the cure. All she has to do is wait a few decades.

In the series finale of The Originals, Klaus Mikaelson offered his sister Rebekah what she wanted most in the world: the cure for immortality. The Vampire Diaries introduced the cure during season 4.When a member of The Five arrived in Mystic Falls, the story behind the cure slowly unfolded. The witch Qetsiyah created the immortality spell, cementing their love as eternal. After Silas betrayed her, she developed the cure. Qetsiyah demanded Silas drink it so that they could spend the rest of their mortal lives together. When he refused, she locked him in a tomb with the cure. Every vampire in Mystic Falls had a vested interest in finding the tomb, Silas, and the cure.

The search for Silas led most of the main characters, including Rebekah, to a remote island off the coast of Nova Scotia, but it was Katherine Pierce who succeeded in retrieving the cure and freeing Silas. Bonnie Bennett eventually defeated the ancient witch, encasing him in stone (he escaped following Bonnie's death). Damon Salvatore gave the cure to Elena Gilbert, who shoved it down Katherine's throat. Silas drained it from Katherine, and when Stefan Salvatore killed Silas, the cure went with him. However, when Bonnie returned from the 1994 Prison World (an alternate dimension where the cure still existed) during season 6, she brought the cure back with her. History repeated itself when Damon once again gave it to Elena. Bonnie injected Stefan with Elena's blood during season 8, making him human, and in the series finale, Stefan passed the cure on to Damon.

Before Klaus died, he offered Rebekah a peace offering: the cure. He told his sister the cure was waiting for her in Mystic Falls, and he asked Caroline Forbes to get it for her, saying,"In a handful of decades, when it's time, you can go to Mystic Falls and get it. Then if you no longer wish to be a vampire, it's your choice."It's unclear how long Klaus had known there was a second cure, since Damon and Stefan were initially determined to keep its existence a secret fearing for Elena's safety. The cure was never mentioned throughout The Originals until the series finale, despite both Rebekah's and Klaus' desire to procure it onThe Vampire Diaries.
