Double Mikaelsons

I do not own these characters, those rights go to Julie Plec.
Imagine if Hope had a twin sister, she hadn't seen for years. They both hate each other, because Andrea did something horrible that Hope will never forgive. Andrea shows up at the Salvatore School, and pretends to be Hope, while Hope is away on a trip. No one knows about Andrea Mikaelson, except the Mikaelsons. They wanted to keep her a secret after what happened.

What happens once Hope returns? Will everyone believe Hope has a twin? What will happen between the twins? What trouble will Andrea cause in Hope's life? Will Hope ever forgive Andrea?
