No, I'm happy to hear what you think. Maera's picked up a fair bit about humans; whereas very few humans see merfolk, many merfolk see humans. And it's kind of a conversation topic ("Look at how backwards they are on land!") She's probably not as knowledgeable as she thinks she is, but she knows more about humans that Imogen expects.
For the first time in Maera's life, she's facing true difficulty. Life has never been easy but now she's facing really desperate times ahead, and that's why she's worried.
Maybe I should think about making things clearer.
Anyway, thanks for the feedback
It makes my day to see this being read.
