Merlin/The Vampire Diaries AU: Merthur as Delena
Tired of hiding his feelings for Arthur and afraid he will never have the chance to tell him after Camlann’s battle, Merlin reveals his deepest secret to his king. He doesn’t wait for an answer though, he enchants him to make him forget, before he might find out that Arthur feels the same. Before it might be too late to go back.
So Arthur walks away, oblivious again. And Merlin does the same.
