I saw this pool a long time ago. I felt bad for both. Miss has mental issues. Satorin is a baby, judging from the speech and the little basket she's carried in. If she were older, she might have understood..intuited Miss' condition.
This is a perfect case of what is excusable "baby talk". Satorin just babbles what she picks up. A shithead (say) Marisa not only talks trash but has all the telltale mannerisms of gutter trash.
