Her: "Do I need to talk to you?"
"Yes because my commander said so"
"What do you need?"
"Your father(can't remember his name)said for me to tell you that you are no longer needed and will be expelled"
At this point her self worth would plummit into an abyss. Making her perfect for manipulation.
Simply hold her for a bit as she bawwwws (if she does) tell her that you won't let anything like that happen again.
Say that you want to have sex with her as a "symbol of love" (she won't know any better) and keep on doing it. Pretty soon she will come to you.
Be polite for a few weeks about stuff you want her to do. you HAVE to ask her to do stuff. She cannot have any say in what she wants to do. You have to dictate her activities for her.
