The Elijah Mikaelson treatment is when a character in a tv show was originally supposed to be a one-off character. But the people working on the show
like the actors performance so much or they found the original one-off character interesting, that they find a way to make the character important to the main plot of the show. The
definition was originally used by the YouTuber, Kitty
Monk.
"I
don't
like Mina Loveberry from Star vs The Forces of Evil. Why do they keep her around? She seems more
like an unimportant character to me."
"I think she got The Elijah Mikaelson treatment. So that's why she's apart of the show."
