(I DO NOT OWN THE VAMPIRE DIARIES OR TEEN WOLF OR THE ORIGINALS!! sadly. )
Everyone knows the Original Family. They all know Elijah, Kol, Rebecca, Henrik, Finn and Klaus. But do they know the lost child Alexandria? Of course not, her siblings believe that she died with Henrik. So I guess it will be a huge surprise to them and especially Niklaus when they see her. Do you think Nik will be threaten or thrilled to share the crown of being the Original Hybrid?
How do I know this, you may ask? Well it's pretty obvious... I am Alexandria and this is MY story.
