For Better or Worse

The end of the eight weeks is in sight, but the couples still have many hurdles to overcome. Alison apologises to Paul for an affair and reveals the true story behind it. He has to make a decision that will decide the future of their relationship - will he forgive her or not? After the emotional intensity of the apology, Paul takes time out with the other men, as John organises a BBQ to deliver some home truths about the emotional differences between the sexes. To encourage the couples to lock lips, John organises a kiss-in for charity at a central Sydney mall. Inhibitions crumble as the couples show off their newfound sexual chemistry. As the experiment reaches its conclusion, the couples write each other love letters, which are displayed and read in a public gallery.
