To be fair they had not heard from the house in a week, they had no idea who the villain was - they had heard Megan and Gemma denounce John's game playing - so Steph got saved against the odds, good on her for playing against John IMO. Good on Angie for voting the sidekick Kristina too, would love to see her in a double eviction with John lol.
Surprised Stephanie got saved, mays well milk it she had.
