Throughout The Vampire Diaries
The Original Hybrid, Klaus Mikaelson, and the second-known Petrova Doppelgänger and newly-turned human/witch of the Traveler sub-culture, Katherine Pierce, slept together in Graduation and conceived their daughter, Adyelya.
Eventually, Katherine accepts that She is Deeply in Love with Klaus and and Elijah, and is unable to live without Either by her Side; Klaus and Elijah come to Understand that they also both love Katherine too much to leave her, They All agree to enter a Polyamorous Relationship.
Stefan Salvatore is objectively Katherine's best love interest in the series. He was the only person that she loved unconditionally, and it was Stefan that made viewers see Katherine as less of a villain and more of an anti-hero.
After Rose discovered that Katherine had stolen the moonstone from Klaus, she told Katherine she was going to turn her over to Klaus rather than risk her and Trevor's lives. She fed Katherine her blood to heal her wounds. Then when Rose left the room, Katherine hanged herself and became a vampire.
In death, as in life, Katherine Pierce is as selfish as she was over the last five centuries. Just after her daughter, Nadia, dies of a were-bite, Katherine finally can't outrun her enemies. Stefan plunges the Traveler's knife into Elena's body, expelling Katherine's spirit.
Can Hybrids Have Babies? Mules and bananas are examples of hybrids that are infertile, so they cannot have their own babies. But surprisingly, there are many examples of hybrids that actually can have babies. This happens when the hybrid mates with another hybrid, or with the same species as one of its parents.
Literally the explanation is that Klaus was born a werewolf, so he can procreate. Every hybrid on the planet was born a werewolf. The CANON ANSWER is that he triggered the curse thus he can procreate.
In 1490, when she was about 16 or 17 years of age, Katerina became pregnant by an unknown man, a Traveler, and her family disowned her for the shameful birth of an illegitimate daughter.
Nadia was Katherine's only child. Katherine gave birth to Nadia onscreen, though these were in flashbacks in the episodes Katerina and 500 Years of Solitude.
Who are Klaus Mikaelson's offspring? Klaus has two known progeny – Hope and Hayley Marshall-Kenner.
It is revealed that Elena is a Petrova Doppelgänger (like Katherine, Amara and Tatia), which is thus responsible for her being identical to her ancestor, Katherine Pierce (née Katerina Petrova). This also has the implication of making her a supernatural creature.
That bloodline eventually lead to the Flemming family (Elena's birth mother). Isobel Flemming gave birth to Elena. So, Katherina is Elena's ancestor. Katherine is like her great great great great grandmother.
The two of them discuss what happened between Stefan and "Elena" and Caroline also tells him about Nadia and Matt and the text he sent to her. From Matt's text, who used "K" and not "E", they put the pieces together and they realize that Katherine is in Elena's body.
