I don't think there is any way anyone here can answer those questions with the lack of information about the situation. Also, not all t's operate the same. Just because a t isn't ethically obligated to report a situation doesn't mean they won't if they have enough victim identification information to do so (ie. names, addresses).

Maybe your friend could ask her own t to know for sure, posing her questions as hypotheticals and not giving away any identification of others.
