The rest of the TVD cast as their assigned characters but Stephen Amell plays Alaric! 

Now as for Kol, he is still played by Nathaniel Buzolic. If you rather imagine someone else as Kol, that is fine! But the reasons why I did not change him is because he is the only person to resemble Daniel Gillies and I can't imagine anyone else as Kol.

I do not own these characters except Antonius, Kathleen, Celine and Eun Mi. All other characters from TVD are owned by Julie Plec!
