However, her older sister Rachel arrives and tells Jack that Natalie is hiding that she has not got good grades at school in Scotland. For her own good, Jack sends her back home.

Jack provides a home for the Dean family after their eviction from their home. After first being sceptical, he soon warms to the family. Jack then begins a relationship with Frankie Dean (Helen Pearson) after the collapse of her marriage to her husband Johnno (Colin Wells), and the couple later marry, after five years being a widower following the death of his wife, Jill. Frankie's three children Jake, Debbie and Craig accepted him as a new father, however Steph will never accepted him as her new father and refused to be close with him, causing Frankie and Steph's siblings angry at her, but, they understand that she remain close to her father Johnno. The nadir was when the Dog was destroyed in an explosion Jack and Frankie were out for a meal when the Dog exploded and Jack and Frankie nearly lost Darren, Steph, Craig, and Jake as they were trapped inside the pub when it exploded and caught fire. While they used insurance money to rebuild the pub, they stayed at a grimy bed and breakfast where the owner constantly treated them poorly. They were kicked out, and briefly lived with the McQueen family until finally Frankie could take no more and forced Jack to use the insurance money he had been pocketing to pay for a nice hotel until they could go back to their apartment. Jack and Frankie decide to start fostering disadvantaged adolescents. They first foster Barry "Newt" Newton (Nico Mirallegro).

During a game of poker with Mike Barnes (Tony Hirst), Tony Hutchinson (Nick Pickard) and Warren Fox (Jamie Lomas), he bets his half of The Dog, which Warren wins. After finding this out, Jack suffers a heart attack and Darren is told to leave the house. Warren then signs his half of The Dog over to Jack again for a low price. Despite this low price, Jack goes through money worries, and begins to water down drinks. An inspector finds this out and declares he is to take him to court. Seeing no other way, Jack decides to commit suicide so his family can claim his life insurance money. However, Darren stops him. They then discover the body of Eamon Fisher (Derek Halligan). Darren tells Jack that they could fake his death, claiming Jack is the deceased body. Jack goes along with this and his family are horrified at his apparent death. Frankie discovers Jack is alive and the pair agree to flee to Spain. Niall Rafferty, the secret son of Myra McQueen, finds out Jack is still alive and hiding in the attic of The Dog.

They are both imprisoned. During his time in prison, the Osbornes are forced to sell The Dog to the Ashworth family.

Jack is released from prison four months later. Upon his return, Frankie, Steph, Newt and Darren throw a party for him. He visits Eamon's sons, Kris (Gerard McCarthy) and Malachy Fisher (Glen Wallace), where he learns that Darren had only offered to buy them a drink as an apology for using their father's dead body in their scam.

In December, he discovered that his niece Eva Falco (Kerry Bennett), Billy's daughter, had been in the village since September, she held Jack, Frankie, Tom, Kim, Esther, Darren and Nancy hostage. Eva forced Jack to admit the truth, he did so, and it was revealed that Jack had framed Billy for murder of a boy called Callum, when in fact it was Jack that had killed him. Eva said she'd never forgive her uncle for framing her father when she was young because he was in prison for the rest of his life until he died. After the admission, Eva pulled a gun out on the Osborne's and she attempted to shoot Jack but ends up shooting his step-granddaughter, Esther. After realising the heartache he caused, he decided to call the police and turn himself in after 48 years. Eva becomes wanted by the police and Jack and Liam help her get away, and Eva thank him for confess the truth.

She turns Johnno down but is unaware that Jack has been trapped under rubble following an explosion at the school. Believing that he is dying, Jack gives Darren a message for Frankie while she simultaneously tries to contact him to apologise and reaffirm her love for him. When they are unable to contact her, Diane Hutchinson (Alex Fletcher) goes to the Osbornes and finds Frankie collapsed. Jack survives and is taken to hospital where he is devastated to find out that Frankie had suffered a stroke and died. After walking in on Mac Nightingale (David Easter) as seeing his wounds, Jack quickly works out that he is responsible for trying explosion and is therefore the reason that Jack wasn't with Frankie when she died.

Mac then unsuccessfully tries to turn off Jack's life support. Jack is visited by Frankie's ghost, who convinces him to go on living. The two say a final goodbye and Jack wakes up.

In January 2020, when Breda fakes having dementia, Jack plans to move to Portugal with her to spend their last days together, however Breda was using this to escape from being caught for the murders she committed. Jack realises he needs to stay and help Darren, and Breda breaks up with him before attempting to kill Darren by stabbing him in the back. After Breda is caught out, Jack is questioned by the villagers about how he didn't know what she had done, and still grieves her death despite knowing her crimes.

Characterisation

Lucy Allan described him as "Jack the hero!"^[3] The Daily Record described him as "an ex-copper who takes no nonsense from his regulars – although most of them seem to be underage".^[4]

Financial issues

The Osbornes suffered financial crisis when Darren's gambling addiction grew out of control. It was announced that Jack would fake his own death to claim on the life insurance.^[5] Darren found Jack about to commit suicide, before finding the body of Eamon Fisher. Darren and Jack decide to fake Jack's death, which Jack reluctantly agreed to. A Hollyoaks spokesperson spoke to Digital Spy saying "Jack's at an all-time low and the finding of a dead body is too good an opportunity for him and Darren to pass up. They swap the dead man's identity with Jack's, forcing Jack to slope off into the night. Darren's then left with the formidable task of telling step-mum Frankie of the 'death'. As Darren's tangled web of lies continues to grow, he's left in an extremely tricky position when he learns that Kris and brother Malachy are searching for their father. It's only then that Darren discovers the true identity of the corpse. Will Darren be able to keep his cool, or will he crack under the pressure? It's only when Jack turns up at his own funeral that Darren realises that the situation has truly spiralled out of control".^[5]
