"You owe me an arm, cousin." Jaina bared her teeth, too ferocious to be called a grin. The raised lightsaber cast half her face in sharp violet light, left the other side covered in shadow. "And I'm here to finally collect - with interest."
Kylo Ren snarled back, and charged.
Red and purple clashed, broke apart, swiped and spun and collided again. Ren was taller, clearly stronger, but Jaina danced around him in such a way it didn't matter. He bore down with devastating power, she twisted out of the way. He lunged faster than the eye could follow, she leapt over him to land on the other side. He flung out a hand, unleashing the Force in an overwhelming wave, and she jumped, spun in place, turning body and blade both parallel to the ground before landing as delicately as a leaf upon water.
Every avoidance swept Kylo into a higher rage, and clearly, that was what the Jedi wanted.
"Emotion," Jaina smirked, "Yet peace."
"Don't you dare-"
"Ignorance, yet knowledge-" Kylo Ren howled, launching himself forward yet again, lightsaber blurring as he hacked and slammed and desperately tried to cut his cousin in half.
But for the first time in their fight, Jaina did not dodge.
"Passion, yet serenity," she went on, voice turning stern rather than amused. Her blade swept up, meeting Kylo's blow for blow, an impassable defense that gave no ground, exposed no weakness. "Chaos-"
"Shut UP!" Blazing red swept down. Shining purple turned it aside. Jaina's grip upon her weapon became one handed, her mechanical arm letting go, pulling back - metal plates parted, and a second lightsaber came out.
"Yet harmony," she said, before white plasma burst forth, spearing through Kylo's chest before he could pull back. A strangled gasp wrenched free of his throat; slowly, the man tipped forward, the strength going out of his limbs as he sagged against Jaina's steady form. She took his weight, still unmoving. In her cousin's ear, she murmured, "Death, yet the Force."
Kylo Ren died with a soft wheeze.
When Rey and the others arrived, they staggered to an immediate halt. The former Ben Organa laid on the floor, his cape unclipped and draped over him as a makeshift shroud. Jaina continued to kneel beside his body, eyes closed, both her deactivated lightsabers in hand. One built by her own hands, powered by a sea-dragon pearl won from Ahch-to’s depths; the other borrowed from a memorial site, with the promise she would bring Aunt Soka's murderer to justice.
“...I need to build a pyre,” the young woman eventually murmured.
Rey twitched. Finn clenched his hands. Poe glanced away.
Rose took a step closer.
“Would- there’s, wood furniture, in a fancy room upstairs. Would that work?”
Jaina took a deep breath, and let it out slowly, releasing fifteen years of grief and lingering anger to the Force. “Yeah. That’ll do.”
