Andrea comes to
Erinsborough pretending to be Dee Bliss. She tells Toadie Rebecchi (Ryan Moloney) that she got a brain injury in a car crash with him, but that she was found by a woman named Emily, who did not call for help, as she believed she was protecting her from Toadie. She explains that she saw him with Sindi Watts (Marisa Warrington) and did not want to ruin his happiness. Toadie asks to get a DNA test to prove her identity, but Andrea says they cannot ask Dee's sister,
Cecile Bliss (Molly McCaffrey), for a sample, as she is dead. Mark later obtains a sample of Cecile's DNA and Andrea gives Mark a strand of hair, causing the DNA results to confirm that it belongs to Dee. Andrea tells Toadie that Willow Somers (Mieke Billing-Smith) is his daughter. Toadie's wife, Sonya Rebecchi (Eve Morey), asks for a paternity test and it comes back as positive. Andrea later explains to Willow that she replaced Willow's swab with one she took from Sonya and Toadie's daughter, Nell Rebecchi (Scarlett Anderson). It emerges that Andrea wants the money from the Bliss family estate, and that Andrea and Sindi not only devised a plan for Andrea to act as Dee, but that Sindi posed as Emily over the phone. Sindi demands her initial cut of $20,000 be doubled to $40,000, but Andrea finds out that there is no more money left in the estate. Andrea tells Toadie that she has feelings for him and after Toadie gives Andrea a cheque for $100,000 for Willow's education, Andrea flees for London with Willow. Toadie follows them, leading to him and Andrea having sex. Toadie then finds Andrea's passport and she admits that she is not Dee. He rejects her and leaves. Willow attempts to convince Andrea to return the money, but she refuses. Months later, Andrea watches Toadie and Sonya renew their wedding vows. A year later, Sindi tells Toadie that Andrea is in
Perth. She then brings Andrea's son, Hugo Somers (John Turner), to Toadie's house and informs Toadie that he is Hugo's father. Willow explains that Andrea left Toadie a note asking him to visit her. Willow convinced Andrea not to tell Toadie. Andrea developed post-natal depression and left Hugo in Sindi's care. Sonya discovers that Andrea is in a psychiatric hospital, so she and Toadie take Willow and Hugo to visit Andrea, who fails to recognise either of them and claims to be Dee. Sonya and Toadie agree to pay for Andrea's ongoing treatment for Willow and Hugo's sake. Months later, Andrea's mother, Heather Schilling (Kelly Armstrong), visits her and she reveals that she has conned the Rebecchis into hiring her as their nanny, Alice Wells, so she can destroy their marriage, leaving Toadie free to be with Andrea. Andrea tells Toadie that she knows she is not Dee. Heather's scheme fails and she flees Erinsborough. After Andrea sends a social worker to assess Sonya in the custody case for Hugo, Sonya visits her in the hospital and explains that she has ovarian cancer. Andrea signs over full custody of Hugo to Sonya and Toadie, in return for them dropping the fraud charges. Before Sonya leaves, Andrea tells her that while she was in the
Salamanca Market, a man approached her thinking that she was a woman named Karen, who Andrea suspects could be the real Dee Bliss. Weeks later, Andrea receives a text message from Toadie's brother,
Shane Rebecchi (Nicholas Coghlan). Andrea moves to
Geelong, where Shane informs her of Sonya's death and asks her to explain the Karen story. Andrea explains that the man thought he had spent an afternoon with her. Andrea follows Shane back to Erinsborough, where she gets a cold reception from Toadie. She tells the Rebecchis that she will help them find Heather and Dee in exchange for time with Hugo. Andrea introduces Toadie to
Ian Packer (Nathan Carter), who tells him that he met Dee years previously, now living under the name of "Karen". He tells them that Karen moved to
South Africa, but this is a lie orchestrated by Andrea. She has sex with Ian in return for his part in her new con. Andrea finally comes face to face with the real Dee, after Heather tracks Dee down in
Byron Bay. Andrea pushes Dee off a cliff and returns to Erinsborough to impersonate her again. Her attempt fails and she is arrested. After a DNA test, Andrea and Dee discover that they are twins and Heather is their biological mother. Andrea is sentenced to at least ten years' imprisonment. A year later, Andrea shares a cell with
Elly Conway (
Jodi Anasta). In return for protecting Elly from the other inmates, Andrea asks her to convince Toadie to contact Dee on her behalf. Andrea is secretly contacted by
Claudia Watkins (
Kate Raison), through her lawyer,
Samantha Fitzgerald (
Simone Buchanan), who pays her to start a prison riot to dissuade Elly from having her daughter,
Aster Conway (Isla Goulas; Scout Bowman), in prison with her. Andrea reveals to Elly that she intends on taking advantage of Dee's kindness to regain custody of Hugo. Andrea and Elly's relationship sours when Elly leaves prison with custody of Aster and she tells Dee that Andrea cannot be trusted. In an attempt to reunite with Hugo, Andrea seduces Owen Campbell (Johnny Ruffo) into helping her impersonate Dee again. Owen drugs Dee, allowing Andrea to swap their clothes while Dee is unconscious. She flees with Hugo and Owen. However, Owen later confesses after Andrea rejects him and, with Heather's help, the police arrest Andrea. Dee visits Andrea for the last time before she leaves to find their father Peter Wilson in
Alaska. ==Reception==
