Well they've saved her enough bloody times!
When she was HOH and it was a triple eviction till they realized she was up anyway and they threw in the cash for Aisha to leave and she said no so they threw the cash at Trasha and still no but that week Sandra & Jason went with Priya the next one but lucky they changed the rules. Which wouldn't have mattered anyway, had Aisha or Trasha agreed to go Priya would have not gone regardless.
Then the other time they changed the double to a single over the weekend and Priya would have gone if it was a double.
