There's rather a lot of rooms. In one, a young man stares into the mirror. When the door opens, he stands in front of his reflection protectively. In another, a woman sits, giggling, covered in a carpet of iridescent scarabs. In yet a third, one of the two residents is clinging to the other, who tolerates this while gazing adoringly at a painting of him. Everyone has something or someone, except a handful of people wrapped in straitjackets.
Finally she comes to a room containing two beds and two women. One, massively pregnant, is caressing the wall and humming to herself. She bears a more than passing resemblance to the Singer. The other is the Singer, lying in the bed, covered in bruises. She's harmonizing with her sister's humming, or at least she's trying; she can't always predict the next note.
When the Wastelander enters, she stops humming and lifts her head effortfully. "Oh, thank God," she breathes.
