It's been many years since Klaus and Elijah's death bud finally Caroline found a way (ancient spell/ritual) that would destroy the Hallow without killing the host, so once she gets all the necessary ingredients, she finally convinced her best friend to travel in time and to help the Mikaelsons, so they won't have to take a part of the Hallow and be apart from each other.

What will happen when she will come back to the present? How much will things change?
