If you are interested in working with this therapist, perhaps it would be good to talk to her about your observations and concerns. Tell her that you find these behaviors somewhat strange and ask why she is doing them. Perhaps the way she responds would reveal more about her underlying motives, i.e. whether she gets uncomfortable/defensive, wants to change subject, or can provide clear and relaxed explanations. If I were in this situation, I would be curious enough to raise these things before cutting her loose or anything else.
