Kytana would have spared Luke a glance, if she could have. As it was she didn't wish to take her eyes off of the raging knight before her. Knew it would finish them both if she did. So she reached out with the force to Kylo's former Master [He is simply not ready. I have hopes he will be able to stand before all those he fought against without anger, with time, but right now he is not ready.]
While Kylo raged, Kytana relaxed just a little. Enough that she allowed herself the cough that had been tickling her throat since she teleported, when she tasted the copper of blood she bent forward and spit it out, wiping her lower lip after she did. "If you are not weak. Prove it. Break yourself of this path, because if it was your Grandfather's mission, Luke would be dead. Break the Emperor's hold on your mind, Kylo. You stopped a moving bolt, I know you can break your mind from his." She didn't scream, she didn't rage back at him. She simply tried logic.
Meanwhile, she kept one of her violet saber ignited should she need to defend herself.
