One thing irritates me though: Why does Emily start commenting with "filthy" when it is her goal to study that exact behavior. And judging from later comments she wants to do that, it's not a job she's forced to do.
She might not be saying 'filthy' in a bad sense, but in an ironic way. Sex used to be considered 'dirty' by large segments of society in the past, so she might be poking fun at societies norms.
I'm glad you caught the parallels between the two species. :)
Thank you for reading and commenting @hannes-stoffel!
Oh, that makes sense. And fits the character. Ok, now it's even better :-)
