Merlin is immortal, and Arthur will eventually rise again. But resurrection is not the same as immortality. Will Merlin wait for Arthur all that time just to see him die again? Could Merlin himself make it through seeing Arthur die twice before him and not be broken completely?
Merlin Headcanon:
It takes him a long while - years even (heâs not sure, he stopped counting) - to learn that he couldnât die. Illnesses and plagues came and went, loved ones lived and died (in sibbe gereste, Arthur, Gwaine, Gaius, MotherâŚ), reckless and suicidal missions were won and gone. Through each, Merlin thought he might die, but didnât. As it happens, drowning doesnât work. Neither does poison. Neither magic nor sword do either. He knows, heâs tried.
It takes him a long while - years even (heâs not sure, he stopped counting) - to come to peace with it. Great waves of grief wash over him from time to time, but he is an affront to magic and to life itself if he wastes either. Heâs never certain he deserves this power (punishment), but he has come to peace with it. He sets out to live a life (many lives).Â
It takes him a long while - years even (heâs not sure, he stopped counting) - to realize that Arthur was truly coming back. Merlin is there, ready, waiting at the lake, to greet him, to take him home.Â
It takes him a long while - years even (heâs not sure, he stopped counting) - to realize that he still isnât aging.
Arthur dies again.
It takes him a long while - years even (heâs not sure, he stopped counting) - to feel human again; itâs too much, too much, too much. Heâs still broken when he feels it.
It takes him a long while - years even (heâs not sure, he stopped counting) - to realize that Arthur has many futures. And itâs okay (itâs okay) because Merlin has many futures, or one constant future, or - it doesnât matter, itâs been so long that he stopped counting. He greets Arthur at the lake.
(One future, many futures from now, from then - Merlin begins aging. He suspects that the world doesnât need their help anymore. He follows Arthur home.)
