Point of view thing... irrelevant if she isn't wanting to work on the M. In my dream world you could just ask her if she wants to work on the M or not. If not - you aren't going to let her vent and justify her own guilt. Then walk out the door dramatically.
But probably you should just give her a few days and let her approach you with her desire. It may be she just wants to guarantee you can't hold her own crap over her head.
