The blush turned to a grin as she almost got him. Rey enjoyed the fight, the movement of bodies and the push and pull of power. Luke would always frown at her favor of it, of the joy she felt from it. Maybe she didn't have to hold it back, taper her power and the joy from just letting it flow.
Kylo's admittal to knowing what it felt like to be a slave to someone else surprised Rey. So he had gone what she was going through and had felt it to be best. "Why do you want to teach me?" She asked this, trying to understand his reasons for all of this.
She did a quick twirl of her own sword to keep her wrist limber as she thought about what she wanted to do right now and that was to fight, to enjoy the moment and to beat him. With a quick shove of her magic that was harder than before, she tried to push him back to the tree.
