I not reading this thread until after the season is over so I don't know what else is mentioned, but I see the thread didn't get far this season.
One of Brenda's interviewers yesterday asked her how she felt about Dawn. Brenda said she would be civil but that was about it. She said the Reunion would be difficult. She discussed it in a way that made me believe Brenda has not faced Dawn since being voted out, which would mean she never ran into Dawn at Ponderosa, which suggests Dawn makes F3.
