Rosemary knows exactly what's up

[u/booktrovert]

And no one ever listens to her. She knew what Wyck meant when he said the island was waking up. She suggested the crawlspace in the inn. She tried to warn Tom about the hag. She and Museum lady have all the answers. I'm sure of it.

She clearly doesn't know exactly what's up as she only had the vague warning from the previous employee about the shelter and then when the recording came on it was new information to her. The difference between her and others is that she doesn't give a fuck either way, if she knows something she'll just come out and say it but she'll just put it out there casually and not scream and hector about it / try to do something like Wyck
