Writers then placed Finn in an issue-led story exploring underage sex and teenage pregnancy with Amber Sharpe (Lydia Lloyd-Henry).
[2][3] Marquess commented on the family: "We're very excited about the arrival of the O'Connors who burst onto screens in August with a very dramatic storyline.
Hollyoaks, teaming up with Channel 4 Education's Battlefront, would explore sex involving two 12-year-olds, which would lead to Amber's pregnancy.
Abbie Louise’s campaign Where Is The Love tackles an incredibly important issue which affects many young people today, who feel huge peer pressure to have sex before they are ready, often without the help and advice of adequate sex education at school.
"[7] Of the storyline, Marquess said: "Hollyoaks has long been credited for tackling difficult issues that affect young people in a sensitive and intelligent way.
I am very proud that we are once again bringing to the forefront a subject for our young audience that many parents, politicians and schools struggle to address.
The storyline very clearly communicates to the audience that Amber and Finn were not emotionally or physically ready to engage in any sexual activity.
On 12 July 2011 Finn receives a text message of Amber with a photo attached of their baby girl, Bella.
"[7] In August 2011, Emma Smithwick told Daniel Kilkelly from Digital Spy that Finn had left to live with his father.
His returning scene will see his stepmother Diane reach out to him in prison and mention how she wants him to understand the mindset of rapist, after his sister Sinead is raped by her husband Laurie Shelby (Kyle Pryor).
Upon the announcement of his return, producer Kirkwood will show how Finn finishes his sentence and afterwards whether the villagers allow him back to community or whether he is truly sorry.
After Diane kidnaps a baby from a local hospital, Finn and Amber take the child, but are caught by Anita Roy (Saira Choudhry).
When Amber's family finds out about her pregnancy, she lies that Rob is the father of her baby; as a result, the Sharpes move away from Hollyoaks.
Amber's allegations also lead to the truth emerging that Diane is a former pupil of Rob's, and her relationship with him began when she was still underage.
A few months later Finn receives news that Amber has given birth to a daughter named Bella but he decides not to go to see her.
Sinead plans to go to a party with Robbie Roscoe (Charlie Wernham) and Callum Kane (Laurie Duncan), but on the way they run over Finn.
While on a class trip, Finn and Robbie compete with each other for the attention of Phoebe McQueen (Mandip Gill).
However Finn realizes what Robbie is planning and switches the statement, resulting in John Paul being sent to prison.
Meanwhile, Sinead, who is out to destroy her family, breaks into Finn's laptop, discovering he has been viewing very graphic pornography.
Finn immediately jumps into the role of father, while Diane is suspicious about Amber's true motives.
Later, after learning Diane had paid Amber to leave, Finn storms in the Dog and attempts to buy a beer, however Nancy refuses.
Thinking he had again gotten away with his crime, Finn attends Nancy and Darren's wedding, but leaves during the service when a suspicious Phoebe texts him from Robbie's phone.
Finn casually denies it and once again mocks John Paul that Nancy was man enough to report her attack.
However, moments later while congratulating Nancy, she suddenly realizes that the aftershave Finn is wearing is the same as the one her attacker wore.
In September 2015, Sinead went to visit him for a while to meet her daughter Hannah for the first time, before leaving Hollyoaks forever after she discovers that Ste was having an affair with Harry.
At some point, he attacks John Paul's boyfriend, James Nightingale, who is representing Finn in his legal case to ensure that he does not get out.
Two years later, Diane visits Finn in prison and asks him questions about his actions, hoping to understand the mind of a rapist after Sinead is raped by her husband, Laurie Shelby (Kyle Pryor).
Juliet Quinn (Niamh Blackshaw) grabs Finn's cap running and she throws it inside the classroom.
Sally confronts him about raping John Paul and banishes him from the school, in front of Finn's boss, who fires him.
Agreed with John Paul, Edward, Nancy and Sally, Finn decides to leave the village to be with Amber and their daughter Bella, without saying goodbye to Yasmine.
