the return of the two kings
It takes 1500 years for it to finally happen and its not in the way merlin thought it would. He thought Arthur would return, but when a man that looks exactly like arthur sits beside merlin in his political science class, well merlin realises that reincarnation wasn’t completely off the table.
Merlin introduces himself on the 3rd class, the first two spent of him subtly studying arthur, his face, his mannerisms, trying to figure out if it was really him, though when he heard the voice and name any doubt was swept away.
From that point on they quickly grew as friends. Merlin wasnt really sure what to do, he was told arthur would return when the world needed him, but nothing about if he was reborn again with no memories of his past reign whatsoever.
It stresses merlin out for a while, he constantly was on edge for any world changing dangers, however after a while he just accepted that maybe there was no reason. Arthur was just born again and he should appreciate that.
They quickly grew close, becoming the best of friends and eventually roommates and merlin couldnt have been happier, content with have the blonde back in his life.
Until one day he gets this urge to walk near the lake of avalon again, something hes not felt like doing since he found arthur again. But he does, distantly thinking it was around this time of year he had lost his king all those years ago. So he goes, the sun still rising as he begins his usual route around the lake. He takes it in, smiling at how much life has changed since he last took this walk.
He was distracted so you cant blame him for how much he was caught off guard, really that wasnt his fault.
Despite what anyone who saw would say Merlin did not let out a scream.
He spins around and comes face to face with his best friend, his roommate, his destiny walking out of the lake soaking wet.
“Arthur? What are you doing here? And why are you in the lake? I-“
He pauses, the air ripped out of his lungs as he realises what hes actually looking at. Something was different. Something was wrong. Because this arthur wasnt wearing his usual jeans and jumper, his hair wasn’t slightly too long because hes been too busy with work to get it cut, he wasnt making some joke about merlins poor coffee making skills.
He was wearing chainmail and armour, a sword in his hand one that merlin hadnt seen since that day.
This wasnt the same arthur he left at home this morning, the same arthur who was too busy watching last nights football on catchup to make fun of merlin burning his toast, the same arthur who he has lived with for 6 years and thought was his arthur.
No, this was the same arthur that he held in his arms as he thanked him and took his final breath.
Merlin doesnt know what kind of sick game the world is playing on him but that doesnt matter,
Because now theres two Arthur Pendragons gracing this earth and merlin doesn’t think hes quite as cut out for this destiny thing as he thought he was.
