The 100 AU: Bellamy and Lexa as Trikru-born siblings
(requested by @cvndlehoe)
Bellamy and Lexa always compete with each other, even with the simplest of tasks. “I bet I can catch more fish than you.” “Oh yeah? Watch me pick more berries, too."
Until they’re both chosen for the conclave, and their nightblood becomes a curse instead of a blessing. They’re scared. Bellamy and Lexa have been competing their whole life, but never like this, never with the intent to harm. And now people are dying. The other nightbloods are turning on each other.
Bell looks at Lexa, says, "if it comes down to me and you, i want you to kill me.” And Lexa stands there, feet planted in the ground. She’s shaking her head slowly, not comprehending at first what he’s asking her to do. Lexa can’t harm her own family, her own blood.
It does come down to the two of them. Bellamy looks at his sister, as if memorizing her face, bruised and bloodied. He drops his knife, letting it fall with a certain finality to the dead leaves at his feet.
Lexa drops her weapon too. She looks Titus in the eye.
“Kill us both. I won’t take my own blood down.”
