London, Andrea and Toadie have sex and Toadie's wife, Sonya Rebecchi (Eve Morey), watches it via Skype. Daniel Kilkelly of Digital Spy called it the "ultimate betrayal." When Toadie discovers that Andrea is not Dee, he leaves. Of the storyline in London, Moloney reported, "Of all my storylines over the years, Dee's disappearance is definitely one I'm most asked about, so it's great that we're able to add an international element to this latest chapter." Family introductions Part of Andrea's con, which involved a DNA test from Willow, was not initially revealed to viewers. Herbison said of Willow's introduction, "It's always a great dynamic when you have a child who's forced to parent an adult. She really was a leaf blown about in the breeze created by Andrea." Willow goes against Andrea multiple times, and runs away from London to try and escape Andrea. The following year, Sindi Watts returns to Ramsay Street and reveals that Toadie has a son named Hugo, whose mother is Andrea. Willow then explains the story of Hugo's birth to Toadie and Sonya. In 2018, Neighbours producers introduced Andrea's mother, Heather Schilling, played by Kerry Armstrong. Heather comes to Erinsborough as Alice Wells, a nanny for the Rebecchis. She tries to poison Sonya in an attempt to unite Andrea and Toadie. After Andrea is sent to prison in 2019, the real Dee suspects that she and Andrea are related, ultimately discovering that Dee and Andrea were twins, separated at birth, with Dee being adopted by the Bliss family and Andrea remaining in the care of Heather. Returns At the end of 2017, Andrea is seen watching over Toadie and Sonya renew their vows. For this scene and her upcoming appearances in 2018, West was not credited as either Andrea or Dee, but instead simply a guest appearance. McMullan of Digital Spy stated, "So, when 'Andrea' reappeared this month in a psychiatric hospital, eagle-eyed fans quickly spotted that Madeleine West was given a unique credit as "special appearance" without a character name. If this isn't a clue that Neighbours want us to think there's something amiss, we don't know what is." Additionally, he added, "What does it all mean? Either the Neighbours bosses are playing games with our hearts, or the real Dee is alive, but doomed to be accused of being Andrea Somers. Talk about a twist of fate."
