Back in Africa, Kelly G said that the jurors were watched and not allowed to talk game. Yes, it certainly seems to have changed. No doubt their psychological health is improved by getting to talk out their feelings of betrayal and such.In Tocantins, I think Brendan lobbied hard for JT. Not sure if he needed help, but by the time Stephen faced them, he had no shot at all.
Note: in the Outback, the jurors didn't stay on the ranch the whole time. For example, we know that Alicia and Jerry went on a trip around Australia. That changed. Now the jury only gets to do day outings.
