Oh, she and Lord Vader have gotten into arguments before about his lack of sleeping. She knows there are things she cannot possibly understand about his nightmares. She knows that his nightmares are only a part of the reason he doesn't like to sleep. But, she also knows that he needs sleep. He feels better after he actually sleeps and not just dozes. Plus, if he dozes, she can work a little bit tonight, even while she's keeping watch.

She smiles at Luke, amused at his concern. "If something happens, I won't be far from you, and you can roll out of the shelter, and rescue me." She's teasing. She very, very rarely needs rescued and once had been because that Toydarean, Treeko, had sent a bounty hunter to find her when she was fifteen. Lord Vader had not taken well to such a thing happening.

"Really, Luke," she uses his name for the first time. "I'll be okay. I'm going to get into an argument with your father," still weird to say, "and then, I'll be meditating most of the night. It'll help my focus, and allow me to protect all three of us." She knows that if the Rebels come upon them, likely the only person to get out unscathed is Luke. "You have been through an emotionally and physically taxing trial. It's okay to let someone else bear the burden for a moment." She says gently.
