The fussing is coming. There's no way Vader is getting out of it. The only way he can is by sleeping, which means, she wins anyway!

She presses her presence back against him, reassuring him that his son will be safe and cared for. She would never allow anything to happen to Lord Vader's Son.

To Luke, though, she just holds onto his hand and bumps him genially with an elbow. "You're welcome. And you'll find that I'm right, rather often." Especially when it comes to physical complaints. She knows both men are exhausted and sore. She also knows this isn't the worst Vader has been. But he doesn't have anything else to prove. Palpatine is dead.
