Damon had turned you into a vampire centuries ago, and since then you've been together. That was until a war broke out between vampires and you two separated - ending up on different sides of the war. Damon thought you had died and was completely devastated.

When you went to deliver the drink, you realized that you already knew the person - who was rather cranky when he turned to look at you. He hadn't recognized you yet

"What took you so long?!"
