Additionally, Suzy and Laura discuss her issues (or how Suzy reacts to her parents thinking she has issues) during the bathtub scene.
Becky, the operator, also talks to two women with names, though they don't appear on screen. As the phone operator she speaks with the two operators on the other ends, Judy, and one other, whose name escapes me. They can be heard talking on the other end and connecting them with Sam's foster parents or Social Services.
They talk to each other a few times throughout the movie (although it seems mostly about Sam), but during the bathtub scene (after the Bishops bring Suzy home), Suzy tells her mother that she hates her. Laura assures her that she doesn't mean it, that it's only her emotional state making her say these things.
It's a brief exchange, and since the emotional state was brought on by her forced breakup with Sam, it's dubious.
But I think technically it should qualify.
