In a similar vein, look at Jasmine Chodhury (whose name I just butchered). In Destiny, when she found out the Borg were heading for Deneva where her family was, she called her hushand to warn him to leave BUT she wouldn't tell him WHY was because the Borg were coming. He had the good sense to follow her direction even though his wife couldn't give him specifics.
Actually, the character in Destiny
who warned her husband to take the kids and run was Miranda Kadohata, and her family lived on Cestus III, which never came under direct attack by the Borg.
Jasminder Choudhury is the one who lost her entire family on Deneva. She, however, never broke protocol to warn them (not that she had to, since much of that sector was already in a state of emergency).
