If she didn't tell Dawn anything, than votes would be as follows:
Corinne, Malcolm, Mike, Eddie, Reynold, Erik: Sherri
Sherri: Phillip maybe?
Phillip, Cochran: Eddie or Reynold
Andrea, Dawn, Brenda: Reynold or Eddie
Assuming split vote happens where guys vote 1, girls vote, 1. Little does Philip know that 2 men and one women are not doing the split vote.
Than after this, starting with Philip, they all get picked off one by one.
