With the Antiques Roadshow coming to Chigwell, Sharon, Dorien and Tracey go into Tracey and Sharon's loft. Sharon discovers some letters written by her mother suggesting either she or Tracey were adopted. After some arguing between Sharon and Tracey, Sharon invites round their mother's sister, Auntie Sylvie, who finally tells them that they were both adopted but they are still biological sisters. Meanwhile, Dorien goes to the Antiques Roadshow with a family heirloom, but to her horror discovers the Russian Empire vase is in fact a mid-20th century East End fake.

Auntie Sylvie,just out of hospital,comes to convalesce with Tracey and Sharon and proves to be very demanding,as well as encouraging Garth to buy a motor-bike against his mother's wishes. They consider putting her in a home but feel unable to go through with it though fortunately she has a mind of her own.
