I have to second Kimp.
a) Near to impossible to contact her, Im' sure.
b) Most likely she has very good reasons for doing what she has, and (don't take this the wrong way, but) I doubt she's want a 16-year-old stranger questioning those ways. In her eyes I am sure that she thinks it is best. Plus you do not want to jeopardise any future chances of him returning
c) For the time being at least it seems best to just leave the situation alone...
