I didn't see the last few seconds of the show, a disservice rendered by my DVR. It stopped recording just before the end of the show, and I didn't catch the last scene after she opened the door. I have now caught up on exactly what she said at the very end.
She hasn't been living with Peter, has she? Her situation has been one of conflict all along, what with the affair with Will. I know she can continue the practice of law (a notable example of a governor's wife as lawyer was, of course, Hilary Clinton, who was probably the highest earning lawyer in Arkansas before he ran for President in 1992.)
