It's such a childish question. Like asking why the sky is blue or where the water goes after it passes them in the steam. She's more interested in that stiffness to him. The first time they had sex a week and a half ago was her first time with anyone. No one else has been safe enough. The other boys would tell everyone. She'd be in trouble. And she never wanted them as much. Just wanted to compete with them. Her hand slips down to cup his flat stomach, fingers dipping into the front of the deer skin pants. The tone Jack uses when he asks isn't childish. And she knows he's not as soft in the head as the men think and it's mostly a language barrier. So she tries to answer.
"White monsters. Understand?" She leans back enough to see his face, trying to use small words he might know. The French are white but not the Spanish. Yet they both wear the odd clothes and carry swords. Swords like Jack. "Braves Hecetv." She points to her eyes and then sweeps the hand that was touching him out- indicating the forest. "Whites..." She considers it for a moment and then pulls her own hair, making a face or fear. Her closed fish comes down on the chest with a stabbing motion. "Chief says..." This bit is going to be hard to explain. "No fight. Tribe-" A hand to her heart and then his. "Tribe no fight. Whites no fight. Apart." She holds both hands flat and separate. "Braves hecetv whites. Want to kill. Before they come."
As long as they're asking questions- "Why does Jack have white weapon and white clothes?"
