How does Miranda fit in with the other actors on her first day?

Anne-Marie sits in the front of the room, in a stiff, upright posture, which Felix says shows “no inviting slouches” (151). After the men get their role assignments, she offers to rehearse the “mushy stuff” with Ferdinand, but Felix keeps her with him to rehearse her parts with Prospero. In this way he keeps her apart from the other men.
