In what could turn out to be the most important day in the 'Big Brother' (Thu., 9PM ET on CBS) house, it was down to Adam or Shelly for eviction. Porsche's greed absolutely saved the veterans when she forced the duo twist back into the competition for a week, and Rachel subsequently won the POV.
Rachel is a big threat in challenges anyway, so she was going to be difficult to get rid of anyway. Giving her the power to also save Jordan when there are only six people in the house is 'Big Brother' suicide. Especially with Porsche the outgoing HOH, because she's probably the strongest challenge competitor in the house besides Rachel, and she can't play.
