@sechel
have a look in She’ilat Yavets end of Tshuva 5 where he brings numerous examples of people [who are wothy of hora’a] being holek on their rebbi -even muvhak.
So i would suggest to CS not to tell her brothers yet that she is besting all those non habad people even though she never learnt in a yeshiva.
Same to sechel….
