The Originals family, a powerful family of Originals vampire, they’re all heartless with the one who aren’t their family or close friends. Mikael Mikaelson, the father of them, and Esther Mikaelson, the mother, had another baby. But they were all born since 980/981 after JC, so a big age gap. You born in 2010, and not even a vampire. Esther and Mikael were afraid that they would threw you away or even kill you. Klaus had the idea to kidnapped you the second you birth. Obviously, Kol was agree with. They were going to stole you from their own parents
