One possible plot could be that Davina and Kol discover the pregnancy unexpectedly. They might face many challenges. For example, they would have to deal with the reactions of their families and friends in the supernatural world. Some might be happy, while others could be worried about the implications of a half - witch, half - vampire baby. Also, they would need to protect the unborn child from the many threats in their world.
One possible plot could be about how Davina's pregnancy affects her relationships. For example, it might strain her relationship with Kol as they face new challenges together. Maybe the other characters in The Originals have different reactions to her pregnancy, some being supportive while others are worried about what it means for the supernatural balance in their world.
The plot twist could be that Kol and Davina find out that the pregnancy is part of a prophecy. However, the prophecy has been misinterpreted by many. They initially think it's a good thing, but as they dig deeper, they realize that there are dark forces at work trying to use the baby for their own evil purposes. So they have to fight against these forces to protect their unborn child and their future together.
For Davina, she would become more cautious. As a mother - to - be, she would no longer take risks as easily. Her focus would shift from just her own powers and place in the supernatural world to protecting her unborn child. Kol, being the father, would likely become more responsible. He has a bit of a wild streak, but the pregnancy would make him think twice before getting into dangerous situations.
Kol could be the father. Given their relationship in The Originals, it would be a likely scenario. Their relationship was complex and a pregnancy would add another layer of depth to it.
One possible plot could be that Kol turns Davina into a vampire out of love. He doesn't want to lose her to mortality.

She and Kol then have to face the wrath of the witch community who see her transformation as a betrayal.
