So basically it's say Cassi wins the America's vote and Dani's evicted next week. Dani and Cassi will battle each other and one of the 2 will go back in?

That's stupid. We should just vote someone back in and that be it. Why does the last evicted person from next week get to battle when America didn't vote for that person
