Sword
Her hand closed over the sword that Finn handed her. She saw his look, and understood that he believed Lincoln would not return. A low shudder raced through her, then she slung the sword over her back, tightening the straps so it fit her small body.
There wasn't time to grieve as they prepared to battle the army of Grounders that were approaching. Lincoln had begun to teach her the basics of using a sword. She wasn't great yet, but she could use it.
She saved her brother's life, proving to him, that he was wrong. When Lincoln found them, behind a tree, as she had an arrow sticking out of her thigh. He took her away from the fight, to get her the care she needed.
He enjoyed seeing his sword strapped to her. As he carried her away from the fight, until they reached the river. He promised to teach her to use the sword, he had been planning on giving her the sword in the event that the plan hadn't worked out with the Reapers, he had wanted her to have it.
Octavia loved the sword, it felt rigt in her hand, and she enjoyed having something of Lincoln's, something that could save her life.
