Where do they find Margo and how does she seem?

Q, Ben, Radar, and Lacey find their way into the sleepy downtown of Roscoe. They search the Algoe area and find an old general store. When they enter, they find Margo in a Plexiglas quasi-cubicle, writing furiously in her black notebook. She is alive and has merely relocated. Margo is makeup-less and seems mentally dead.
