I am also okay with her sensing him; he can mask his presence and go "haha I like my privacy", and usually shiels/blocks past surface - let me know if she wants to try to get past it, he's a tetchy little bitch who's happy to share some very unpleasant things.

Sadly his surface emotions are usually less enlightening than most people would hope; he's usually got a layer of something blending misanthropy/mistrust/paranoia and a swing between apathy and curiosity along with whatever else is going on.
