S1, E4: The siblings' mother, Marion, insists that Hannah looks after her for two days whilst she is temporarily blind after laser eye surgery, but Hannah feels enslaved by her. Dan dates Izzy, the free-spirited doctor he met at the STD clinic, and falls in love. Hannah and Dan take Marion to Izzy's party, where Hannah and Marion bond when they take revenge on Izzy's strait-laced flatmate Pete, though the bonding ends when Marion gets her sight back and is not happy for Hannah to attend her Tae-Kwan-Do class. Dan attempts to prove to Izzy that he is a sexual being, but it ends horribly when he electrocutes himself with two dildos wired to a car battery.
