What happened?

So a few weeks ago, they all agreed the last traitor had to be a man, which would make perfect sense since 3 traitors banished were all female.

Then watching last night, it didn’t seem to be ‘a thing’ anymore. It was more of ‘why am I still here’ so it must be Rob. Why wasn’t the “it has to be a man” part of the discussion with Maura and Mark.

Then at the round table, Natalie didn’t even bring it up that it had to be a man. Did they all just forget what they talked about a week ago?
