Nope. Don't deal with her at all. If she makes a big deal about her family, just shrug and say they called you. Then walk away. She'll get mad, but don't let her drag you into her own insecurities.
She did the crime, it's time to deal with the consequences. It's amazing how many WASs are fine at blaming their LBS for things, but once they are called out on their sh*t by their own family, suddenly we aren't allowed to talk about it.
It comes down to one thing...control. She is trying to control the situation, but she's going to have to learn that she can't. She has to learn to take responsiblity for her actions. It's not your job to do so. She didn't respect you by having an A, so you don't have to honor her wishes. I think an A is much worse than talking to family. Don't you agree?

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
