Declan Napier calls Diana to tell her that some money has gone missing from the Lassiter's Hotel account and Diana arrives in Erinsborough. She goes to Charlie's for a drink and Declan calls her and says that the situation with the money was down to a software glitch. Diana see Paul Robinson arrive and she goes over to him. Paul introduces her to Declan and Diana tells him that if there is any dirt to be found on Paul, she will find it. Paul later introduces Diana to his son, Andrew, and his wife, Rebecca. Rebecca invites Diana for dinner and Diana asks to meet Declan to discuss why he called her. Diana reveals to Declan that she knows that Paul has been embezzling money from the company. Andrew becomes jealous of Declan and Diana's bond and he gives Diana some of Paul's financial papers when he tells her about his business idea. Diana calls Rosemary Daniels and tells her that she has evidence of Paul's embezzlement. Rosemary asks Diana to keep her updated on the situation. Paul asks Diana to join him in taking over the company and to prove his loyalty, he goes to Diana's hotel room and sleeps with her. Diana hides a camera in the room and after Paul leaves she checks the tape, but finds Paul has wiped the footage. Diana tries to sabotage an event being held at Rebecca's bar, by taking all of the security for a conference at Lassiter's. Declan pleads with Diana to help his mother out, but
Kate Ramsay (
Ashleigh Brewer) solves the problem instead. Diana asks Paul's lawyer,
Toadfish Rebecchi (
Ryan Moloney), to work for her in bringing Paul down and he agrees. Diana discovers that Paul is blackmailing Toadie into covering up his embezzlement. Paul tells Diana that he has sold PirateNet and that his money troubles will soon be over, before giving her cab fare to the airport. Diana tells Rosemary that she was the one who secured the deal to sell PirateNet and that she did the deal to protect Paul. Rosemary is grateful and tells Diana that she will book her a flight home. Diana asks Paul to come to her hotel room and she tries to seduce him, but he pushes her away. Diana tells him that she is not going anywhere and that she will take everything from him. Paul goads Diana when she comes into Charlie's, he tells her that it was fun crushing her and Diana throws her drink in Paul's face. Diana is about to go home, when she hears that Paul has decided to put Declan in charge of Lassiter's for six months, so he can spend more time with his family. Diana asks Declan to help her bring Paul and Rosemary down and he agrees. Diana begins calling the board members in the hope that she can persuade them to vote Rosemary and Paul out. Paul discovers that Toadie and Declan are working against him and he tells Rosemary about Diana's plan. Diana goes to Declan's office and finds Paul waiting for her. He tells her that her plan has not worked and that Rosemary has fired her. Diana discovers that Paul has written a story about her in his newspaper and she confronts him. Diana tells him that she will receive many job offers in New York, but Paul says that no one will be interested as she is toxic. Diana's plane ticket is cancelled and she is thrown out of the hotel by Paul. She asks Declan for help and he tells her that Paul keeps his business papers in the home safe. Diana kisses Paul, and at the same time she takes his house keys from his pocket and she breaks into his house. Diana does not find anything and, in anger, she smashes Paul's possessions. Diana calls a mystery person and arranges for them to hurt Paul. She then goes to Rebecca and tells her about her husband's affair. Someone goes to the Lassiter's mezzanine and pushes Paul from it. Detective
Mark Brennan (
Scott McGregor) discovers one of Diana's earrings at the scene and he stops her at the airport. During questioning, Diana tells him to speak to Rebecca again after revealing her affair with Paul. Andrew,
Summer Hoyland (
Jordy Lucas) and
Natasha Williams (Valentina Novakovic) follow Diana and see her meeting with
Jack Ward (Peter Lowrey), a
hitman she called on the night Paul was pushed. Natasha retrieves Jack's phone and the group listen to a message left by Diana, telling him to leave town. Andrew confronts Diana at her hotel and Mark arrives to arrest her for conspiracy to commit murder.
Susan Kennedy (
Jackie Woodburne) receives some emails telling her that Diana did not push Paul and she goes to see her. Diana tells Susan that she has been formally charged, but insists that she is innocent. She realises that Susan believes her and she begs Susan to help. Diana is later released. After Paul wakes up and mentions that he argued with Diana, an anonymous caller informs Diana of what Paul said and she begins packing. Mark and his team arrive at her hotel, but they find the room is empty. Diana goes to the hospital to see Paul, he tries to call for help, but he is too weak. Diana tells him that she did not push him, but if she did, he would be in the morgue. She asks him to tell the truth and do the right thing, before leaving through the side entrance of the room. ==Reception==
