Maria and Julia, who shot themselves in the foot by helping the only Roadblocker behind them, Lorena (or "she who screams and falls on her knees when her camel will not cooperate with the milking").

It works, and Lorena and Jason first catch up with The Sisters and then beat them to the mat. Oops.
A reminder for us when we race -- it can bring good karma to help other teams, but only when helping them can't hurt us.
