I’m getting this scene, where the teen son of a ‘modern human’ has this neadertal teen girl out on a ‘date’, and he takes her into a cave where he shows her a neat trick with pigment, making an image of her hand on the cave wall, as evidence of their ‘undying love for each other’. And he adds his hand image with hers as his proof so she can go bakc next week and see the proof.
