Kai and Isabella

This is the relationship between Hybrids Kai and Isabella Parker. Bella is Kai's only biologic daughter with Katherine North. She was kidnapped by Klaus Mikaelson after the day she was born. Since then, she grew believing that Kol Mikaelson was her father until Kai performed a locator spell and found her in New Orleans. Had it not been for her, Kai told her that he would have killed everyone present.

When her grandmother returned to Mystic Falls, looking for revenge after Kai murdered her family, she becomes weak and decides to possess Bella. However, she does manage to possess her for a short amount of time, before being drawn to her son's body. However, she was killed by Brandon North and Kaiaphas Parker ultimately.
