I think the only thing we can really be certain of is that she's feeling a lot of pressure and probably simp numbers are dropping because of other OFs models with just as good if not better tits and showing more than Sophie, and I think Ashley Tervort coming back is a big catalyst.
Sophie had pretty much mailed it in with content being just rehashed boring. But since Ashley and others, there's actually real pressure for her to do more. Ashley's already pushing the envelop a bit, doesn't seem afraid to at least tease tit. Thus if Sophie wants to stay relevant, she'll likely need to follow along or lose simps and subs.
