If Austin had been successfully backdoored, and James (or Jason) went on to win the following HOH, who would they target?
At that point Dark Moon would consist of Jason, James, Jackie, Meg, Becky, along with Clelli and Vanessa. Jason and his friends fully trusted Clay and Shelli, and I presume the trust would have remained solid if Austin had gotten backdoored. The outsiders would have been John, Steve and the twins.
Would James/Jason make a big move and target Clay/Shelli, would they simply target the twins, or would Clelli and Vanessa manage to convince James/Jason to go after someone like John, in order to protect the twins? Clay/Shelli/Vanessa would remain aligned with the twins so it would only be logical for them to push a John boot.
