|“||Kol was a bloody loon. I loved it!||”|
Kol and Lucien first met when the Mikaelsons slaughtered a caravan of nobles. Upon discussing whether to take the nobles' spots and pretend to be them to sneak into a nearby castle, they discovered Lucien hiding. He revealed he was a servant of the castle and after hearing their possible plan, offered to help them with their ruse. The Mikaelsons voted on if they should let Lucien live or die. Kol eagerly voted to murder Lucien. However, Niklaus had the deciding vote and decided to let Lucien live. Lucien led them into the castle, trying to teach them how to dress and behave like nobles. After fixing Kol's hair, Kol threatened that if Lucien ever touched him again, he'd tear off his arm. With Lucien's help, their plan succeeded and the Original Vampires managed to live in the castle, pretending to be noblemen.
