Once upon a time Antonin trusted her enough to tell her everything. She provided an excellent sounding board for him, a confidant he could vent to when his frustrations grew too heavy. Her role as his favorite student allowed her a number of liberties no one else enjoyed. When their friendship shifted to something else, something she couldn't quite label, he stopped sharing his secrets. Perhaps he was paranoid with grand delusions that she would one day betray him. Of course, to his credit, there was some truth to his concerns. She did stab him in the eye with her fork before running away from her home, her family, her Dark Lord, her entire life. It wasn't unreasonable to imagine that she would come back one day to finish the job she started.
