The Originals: IM Elijah Mikaelson
He woke mid-motion inside Elijah Mikaelson's body — suit already pressed, Klaus already in the room, Hayley Marshall already pregnant, New Orleans already a powder keg — and the adjustment period he didn't get was replaced by The Inheritance: a magic-absorption power that builds from every spell, hex, and witch-working he survives in close proximity, growing in the one city on the Continent where magic runs thickest and most dangerously contested. He had watched The Originals four times through, read every production interview, and knew the show's internal logic better than some of its writers — which means he knows the Harvest plot's exact timeline, knows Marcel's political read on Elijah, knows the coven fractures Sophie Deveraux is papering over with confidence she doesn't have. The question that sits under everything is the one the arc raises from chapter one: what do you owe the person you replaced? The Inheritance grows. The suit fits. Klaus is watching with the particular attention he gives to things he cannot quite read about his brother. Hayley arrives from the bayou with a debriefing instead of a request for help and MC recognizes, a beat too late, that it was a relationship test he didn't know was running.
