Hmm, I wouldn't have thought that the reaction only of someone really shallow or damaged. You needn't even be genuinely disfigured-- only insecure enough.

Though it does seem the action of someone who hasn't thought the action through. How long does she imagine she's going to hold her hand like that?

The only way I could see her suddenly having a reaction more social than the way we're told she's grown up is if she's suddenly and intensely attracted to him. Which seems like a different, or perhaps compound, literary sin-- of the author falling so in love with his character (with Bond, that is) that he makes Bond just attract the women like flies, even unlikely ones like this.

But it sounds as though you're going on his depiction of women throughout the book. I've never read any Fleming, so I can't really discuss that point in much depth.
