Piper won't stay in Thailand by the end of the season
Piper reminds me a lot of people I have met who act like they are above their parent's money and want to live a "simple life" while never fully disavowing themselves of the safety net and wealth provided. It is like cosplaying to them. They boast about how they don't need anything from their parents and claim they are self made but when times get tough they run back to the comfort provided. Even if this season ends with no deaths in the Ratliff family I think the knowledge that there is no money for her to return to when she has finished playing at being enlightened will cause her to return home. It is always easy to say that money doesn't matter until you don't have any.
