Someone on Reddit had a nice spin on what Brenda should have done:Actually felt for Brenda - that was cut throat. That reward twist was unfair really.
Regarding Brenda's choice: I would say, "I promised this visit to Dawn, its not fair to take it away. Jeff, can I just give up my visit and let the other 5 go?" And Jeff will say "No, the rules stand." And then you say, "Well then I have to keep it for Dawn."
