And by extension, her - at least if she's going to keep her game up.

He just really wants her to cough it up so he can take a look at it, examine it and see what the meaning is. Because, guess what? He's pretty damn sure she didn't listen and wouldn't think to remember those words from his murmur alone.

And that is a pretty worrying thought because where else would she have heard them?
