There's something in Obi-Wan's expression that tells her he's seen something, or knows it, however it was the Force worked with Jedi at times. She'd experienced it with Anakin's dreams and she knew that sometimes others would learn things while awake... Whatever it is, she holds on to it, grasping the certainty he felt because it's all she has. And she tries her hardest not to think about the fact that he hadn't offered the same certainty in answer to her question.

"Thank you," she says after a few seconds of silence, a sadness in those two words that she wasn't sure she would ever lose. She would still hold to the hope of seeing her children again, but at least she knows that they will live, and considering all things, that's truly the best outcome possible.

A deep breath and then she lets that sadness fall back into place around the edges of her mind instead of at the forefront, instead offering him a small, teasing smile as she points out, "Have you always been this terrible at meditating?"
