Part 2 of my angst Merthur AU where Merlin has the short-term memory of the girl of 50 First dates. For more context read part 1 HERE
Credits to @mine087 and @warypumpkin whose comments/ideas left on the first part I used for this part.
Most days Arthur can fool Merlin. By the time he lifted the ban on magic, he had well-crafted routine. Merlin would wake up asking for Gaius and the druids, who now worked as physicians in the castle, would tell him Gaius went to the suburbs to treat an illness and would be back tomorrow. And when a very upset and confused Merlin claimed Gaius had been kidnapped, they would tell Merlin he must have really hit his head hard because Agravaine's conspiracy with Morgana to kidnap Gaius happened months ago. Then Merlin would get out of his room and discover a Camelot that welcomed magic again and that would distract him enough. Then, in a stroll around the citadel, Arthur would relate him what supossedly happened in the battle where they saved Gaius and finally defeated Morgana.
Merlin: (nervous) So you know? About my... (not able to say it)
Arthur: (casually) Your magic? Yes. You used it to save me and I catched you for once. (sighs) I didn't react well.
Merlin: (laughs a bit) I bet. But I guess you came around. You lifted the ban! It’s exactly how I imagined it! Thank you! You don't know how happy this makes me.
Arthur: (murmurs, with a sweetbitter feeling) You say that every time...
Merlin: What?
Arthur: I said you said that the first time too.
Merlin: (frustrated) I wish I could remember. How Camelot became what it is now.
Arthur: (forces a smile) You heard the druids. It's just a temporary amnesia. You'll remember by tomorrow.
But there were also the bad days. Where Merlin cannot be convinced that easily and finds out the truth by his own means. He would scream and shout in dispare and rage, Arthur always being the reciever of it. Yelling at him for lying to him, for making his life a set up, blaming him for Gaius' dead, his condition, everything. And then...
Merlin: (hurtful) I killed your father!
Arthur: (sighs, swallowing the pain of going through this again) I know. You were Dragoon. You told me that before.
Merlin: And I freed the Great Dragon! I poisoned Morgana!
Arthur: (yells) I KNOW! (Tears well up in his eyes) I know everything. You want me to hate you, to get me to execute you or stop caring for you and it won't work!
Merlin: This was my plan all along. Pose as your friend, manipulate you so you would lift the ban-
Arthur: Stop.
Merlin: (yells furious) And take away everyone you love just as you did with me!
Arthur: (his voice breaks) We are even then.
Merlin: (screams and his magic gets lose, breaking the windows and causing an earthquake)
Arthur: (doesn't even flinch, he's just sad)
Merlin: (drops to the floor and breaks down crying)
Arthur: (hugs him, rubbing his back) I'm sorry. I'm so sorry.
Merlin: I lied about your mother. She was real.
Arthur: (his hand stops rubbing Merlin's back, frozen and eyes wide)
Merlin: (gives a dry chuckle) I guess that one was new.
Arthur: (cries silently, but doesn't let go of Merlin)
One particular night-over year since the accident-someone does something different when Merlin has one of his "bad days".
Gwen: (enters Merlin's room) You are being unfair.
Merlin: (in disbelieve) I'm unfair? I'm the one whose whole life is a fucking theater play!
Gwen: I'm not saying that what Arthur does is okay. Gwaine and I tried to talk him out of it multiple times. But at least he's not doing this to intentionally hurt you. On the contrary, he wants to spare you the pain. While the only thing you do is guilt him and then say hurtful things to him everytime you find out.
Merlin: (resentful) Oh, poor, poor Arthur who doesn't want to deal with the consecuences of his actions!
Gwen: He's been dealing with the consecuences of his actions for over a year!
Merlin: (stunned)... It's been a year?
Gwen: (nods, sadly) I know for you Gaius' dead is recent and it's hard to see beyond your own grieve. But Arthur's been grieving too. He lost his last remaining family in that rockfall... and also a friend.
Merlin: ...
Gwen: (sighs and spots Merlin's parchment, the one Merlin wrote for himself and hided in his magic book and has random entries from the days Merlin found out the truth) Hide that well or they will take it when they search. (leaves)
After a moment of quiet reflection in his room, Merlin resolves to seek out Arthur. But when he arrives, Arthur’s chambers are empty. Deciding to wait, Merlin glances around, curious if anything has changed in the past year. Yet Arthur was careful enough to keep it as how it was a year ago.
Then, something catches his eye—a book on Arthur’s desk, unfamiliar and out of place. Merlin picks it up, flips it open, and recognizes Arthur’s handwriting.
Another dawn. Another day of lies.
Today Merlin moved through the day as if nothing were wrong. He approached me smiling again, asking if Gaius had returned from his trip yet. I told him no, not yet. Not until tomorrow.
I never thought I could despise a word as much as I hate "Tomorrow."
A shudder runs through Merlin. How many times has Arthur said it? How many times has he promised a tomorrow that would never come?
He nodded and joked about Gaius’s terrible sense of time. I laughed. It tasted like ash.
He teased me, rolled his eyes at council meetings, even scolded me for not wearing a thicker cloak in the cold. For a few hours, I could pretend. Pretend that Gaius was just away. Pretend that Merlin was still himself. Pretend that I hadn’t failed them both so utterly.
Pretend Merlin doesn’t loathe me.
Merlin turns the page, his fingers brushing over the smudged ink—tears, perhaps, or the shaky hand of a man pushed to his limits.
Gods, this is worse than battle. Worse than betrayal. Every morning, I resurrect a dead man for him. Every night, I bury Gaius anew.
Is this how Morgana felt?
She, too, lived in a world of half-truths, of secrets festering until they poisoned her. I failed to see her pain until it curdled into hatred. Now I watch Merlin’s face fracture every time he dicovers the truth.
Perhaps this is my penance. For Morgana. For Merlin. For not listening to them when it matter.
Merlin, I was a fool. You warned me time and again and I dismissed you. I called you an idiot, a coward, when all along, you were the wisest of us all. How many times did you save me, only for me to repay you with scorn? I thought I was being a king—strong, unshaken—but I was only proud. And now, when I think of the secrets you must have carried alone, the burdens you bore in silence… I should have listened. I should have trusted you. I'm sorry.
The journal trembled in his grip. Arthur’s pain was raw, unfiltered. Not the king, not the warrior. Just a man drowning in regret. For Morgana. For Gaius. For him. For everything.
Merlin looks at me, and I want to live in that gaze forever. He touches my arm to steady me, and my skin burns. He speaks, and I hang on every word like a drowning man gasping for air.
Gods help me, I love him.
And it is the cruelest twist of fate that he will never know.
How could he? When every morning, he wakes up not remembering the day before? When every night, I am forced to lie to him again? When the truth of my feelings would only burden him further.
I could tell him. Just once, just to see how it feels to say it aloud. But what then? Tomorrow, he would wake up, and it would be gone. And I would be left with the hollow echo of a confession he cannot keep.
No. This is my penance, too. To love him silently. To carry this alone.
So I will love him in silence. And I will let him go every day. And that will have to be enough.
The journal slipped from Merlin’s fingers, landing on Arthur’s desk. The weight of Arthur’s words pressed against his chest, the last confession carving deeper into his heart.
A year. An entire year of Arthur carrying this alone. A year of Arthur waking each morning to carve open his own wounds, just to spare Merlin the pain of knowing. The grieve.
And what has he done in return? Screamed. Blamed. Twisted the knife deeper every chance he got. Responded Arthur's relentless love with nothing but anger in return.
The door creaks open. And Merlin doesn't need to turn to know who it is.
Arthur: (face pale in panic, but eyes and voice exhausted) You weren’t supposed to see that.
Merlin: (turns, eyes with unshed tears) Gwen said it's been over a year since... (not able to say it)
Arthur: Since the rock fall, yes. One year and two months to be exact.
Merlin: And you lied to me. (the first tears fall) Every single day.
Arthur: ... Yes (braces himself, as if expecting a blow, and explosion)
Merlin: Why?
Arthur: (confused, not used to Merlin not exploding) Why what?
Merlin: Why do you do it? The lies, the pretending. Isn't keeping up this charade tiring? Futile? Boring even.
Arthur: ...
Merlin: Be honest with me for once, please.
Arthur: (thinking) Because I love you. (says, smiling sadly) Because for a few hours, you get to be happy. (his voice cracks) And I get to pretend I didn’t take everything from you.
Merlin: It wasn't your fault.
Arthur: (Stunned) What?
Merlin: It wasn't your fault. Gwen is right I've been unfair. I was just mad and hurt and I took it out on you. I'm sorry.
Arthur: (tears well up in his eyes) You don't have to say that just because you feel sorry for me.
Merlin: No! (approaches and takes Arthur by the shoulders, desperate) Arthur, I need you to believe me because tomorrow I'll forget and I won't know everything you've done and how cruel I've been. (cries) I won't remember that you love me.
Arthur: (open his eyes wide, terrafied, tries to deny it) Merlin-
Merlin: I love you too! That's why it hurt so much when you trusted Agravaine over me. But of course you would. He was your family. You would never blame me for trusting my mother over you.
Arthur: It's not the same. You've known Hunith your whole life.
Merlin: Alright, then my father. If my father had appeared out of nowhere, trying to bond with me, would you blame me for trusting him over you?
Arthur: (a flash of pain in his eyes) You did meet him. For a day.
Merlin: (surprised) I told you about my father? (a realisation) Tell me it was during a good day.
Arthur: ...
Merlin: (brings his hand to his face) Gods, I hate myself so much.
Arthur: You were grieving.
Merlin: You were grieving too! And don't change the subject. I just told you I love you!
Arthur: ...
Merlin: (hands holding Arthur's face) Say something.
Arthur: (exhaled, ragged) What's the point? (voice breaking) Tomorrow, you won't remember this. You’ll wake up and I'll have to lie to you all over again. And you’ll hate me for it.
Merlin: Then don't let me forget.
Arthur: (confused) What?
Merlin: (releases him, turns to the desk, grabs a sheet of parchment and Arthur's quill and says as he writes) I write to myself. On the bad days. Notes about the truth. Hiding them does no good if I don’t look for them. (thrust the parchment at Arthur) Read it to me. Tomorrow. And every day after.
Arthur: (takes the note)
The note reads: Arthur loves you. You love him. Gaius is gone. It’s not your fault. It's not his either. Stop hurting him.
Arthur: (doubtful) You think it'll work?
Merlin: I don’t know. But it's better than... this. (gestures between them, referring to the distance, the lies, their broken bond)
Arthur: (still doubtful)
Merlin: (pleads) Please, it's just one day. If it doesn't work, you can go back to your charade.
Arthur: (incredulous) Are you actually allowing it?
Merlin: I know it hasn't seem like it, but I don't like hurting you. If I didn't have this condition I would cool off and apologise by the next day of my outburst. Had I known I've been doing this for so long... (holds back the tears) But if the only way to stop myself from hurting you is staying ignorant of what happened then I'll allow it.
Arthur: You're the one who's been hurting me? (A disbelieving laugh) Merlin, I've been hurting you every day!
Merlin: We've been hurting each other, alright. (holds Arthur's hand) I don't want us to hurt anymore.
Arthur: (shaky breath) Merlin...
Merlin: Can we talk? Properly talk? We still have a few hours.
Arthur: (nods)
And they talk. The good and the bad about the thing they've done before and after the accident. Somehow they end up lying in bed, side by side.
Merlin: (curled against him) I love you.
Arthur: (so happy and so sad at the same time) I love you too. More than I can explain.
Merlin: Will you tell me you love me? Even if I don’t remember? Even if I yell?
Arthur: (promises) I will.
Merlin: Kiss me.
Arthur: (taken aback, unsure) I don't think it's right to-
Merlin: I don't care if it's right or not. (lifts his head, eyes pleading) If this is the only day I remember, then let it mean something. Please.
Arthur: (kisses him)
Shortly after, Merlin falls asleep in Arthur's arms.
That's all I got for now (again)
