My own clexanya au idea contribution:
Lexa is the Queen of a heavily militarized kingdom. Anya is her right-hand woman, the high general of her army, the one who taught a small princess Lexa how to fight when she was barely an adult herself. Anya has loved Lexa for as long as she can remember, proudly watching her become the Queen and standing by her side. She has not confessed her feelings, perhaps she never will, but she is happy to be Lexa's closest confidante and the one she turns to when times get tough.
Lexa has never loved anyone, does not know the feeling, or so she thinks but the truth is she finds so much comfort in her mentor and if she had to describe what love feels like, what she feels for Anya would certainly be what she would describe.
Clarke is a young knight, recently appointed to train in the Queen's private guard. From the moment Clarke enters the throne room she enchants Lexa and becomes hated by Anya. Secret smiles and brushes of hands between the knight and the queen have Anya be extremely hard on Clarke's training, waking her before dawn, sparing and fighting with her so hard the younger girl limps, reminding her its her duty to fight and die by the queen, hoping that maybe Clarke will find it too much and give her position, letting her and Lexa be.
Instead, Clarke grows more and more as a soldier, persistent and resilient, and as she grows Lexa's clear infatuation with her grows bigger.
"She has grown well as a soldier." Lexa comments, eyes not leaving the mock fight betwen Clarke and another soldier.
Anya tenses her jaw, "She is a good fighter, although I find her mouth too smart to be a decent knight with the position of protecting you."
"Well, I like her." Its clearly an admission, a confession of sorts, one that knocks the wind out of Anya, "she reminds me of you." Lexa adds, with a rare smile.
Anya nods, distant, swallowing hurt. Quietly, she whispers "Then why not me?"
Lexa turns to her, face closed but with warmth in her eyes, "Who says it can't be her and you?"
The queen turns her back to the training, returning to the inside of the castle with her handmaids following suit. Anya stays, watching her leave before she turns back to Clarke delivering a final blow, one Anya taught her over and over again, winning her the mock fight.
It is when Lexa and Clarke are finally together that Anya starts to distance herself from the Queen something that deeply hurts Lexa. Clarke knows Lexa loves Anya too, she doesn't care, but she does not want to see Lexa sad like this. So she goes to Anya and extends her hand, asking for a compromise, that she does not need to like Clarke but for Lexa's sake, dont abandon her. Anya angrily says she would never abandon her Queen but Clarke isnt talking about Lexa the queen, she speaks of Lexa the human, the woman who loves them both. Anya shakes her head.
"I can love her enough for the both of us. She doesnt need you."
Clarke sighs, staring down. "If I leave her, will you return to her?"
Anya tenses, "if you leave her you'll break her heart."
Clarke nods, "and you will mend it. She is not happy without you. But if you believe you can love her for the both of us, then perhaps she'll learn to be happy without me."
Anya nods. The next day, she confesses. Her and Lexa spend the night together, and she could not be happier. Lexa looks over the moon. In the morning, after her and Anya share a kiss goodbye so they can go to their duties, Lexa runs to Clarke's quarters, excited to tell her the news, to be with the two women she adores.
But Clarke is gone. A note left on her bed, telling Lexa she has decided to give up her position. That a new battalion leaves in a week to the front lines of a small battle on the frontiers of the kingdom that she will lead it, wishing her all of the happiness she deserves with someone who loves her as much as Clarke does.
Anya is happy when she learns of this. She can love Lexa for both of them, she knows she can. So why, oh why isn't Lexa happy with just her? Why is she crying on her chest instead allowing Anya to love all of her pain away?
