Spot on, Early you keep strength before a merge but after a merge if you're to strong at challenges, leading, making decisions, or too likeable, you'll go.. Also in seasons with past survivors or seasons with multiple tribal swipes its more likely for people to flip between alliances.

The only things i want to talk about after this episode is if Sarah made the right decision, i don't think so.. Also was Debbie the right decision.. I don't think so either.. She was the least threatning of their alliance.
