I don't think Shaughna is anything like Amy last year. Yes she appears to be talking about it a lot, but that could be the editing. That chat with Paige could have been the only time she mentioned it all day but because that's all we've seen of her it looks like that's all she's blathering on about.
And to be fair there's not much else they've got to chat about. They wouldn't be shown discussing anything else, they never are other than "where their heads are at".
Also the intense nature of the villa, of course it's going to be worrying her. She'll have no escape when he brings Molly back.
