What caused Montana’s fall from grace?

So I watched season 3 for the first time recently and, like many people I think, Montana was my early favourite. She was clearly popular with the public given that she was voted most popular female islander (Marcel was most popular male islander) early on because obviously she has a bit of a fall from grace at some point. It doesn’t help that Alex was sorta boring, but other well-loved islanders have made it to top 4 with boring partners before.

Can someone who watched it in real time chime in on what caused the public’s opinion of her to change? I wish I could go back and watch the old seasons in real time and follow along on twitter because I’m really interested to know what the public chatter was at the time.

For me, there was a comment she made at one point to someone (I can’t recall who) about how she was essentially getting tired of having to support or be there for Camilla all the time. I always knew she wasn’t a warm and fuzzy personality but it seemed rude of her to complain about having to be there for a person in the villa who was well-loved and had been there for everyone else. That’s when she took a bit of a turn for me, plus the drama with Gabby who was insecure I think but had good intentions and who I liked.
