Sarah gets a glimpse of just how dark things have got for Bethany when her daughter fails to show up for a day at a wedding fair because Nathan wants her to go to one of his dodgy parties. Sarah goes to the apartment and finds Bethany drunk on the couch while Nathan is out picking up his mate Ian. She manages to get her out of there, but we don't think a clearly brainwashed Bethany will be thanking her for it. Also tonight Kate starts to have her suspicions that someone in the family is having an affair, while Rosie and Adam search Daniel's room for evidence that he was behind Ken's attack.
