At one point, she starts stealing from Bettabuys just to put food on the table, but looks forward to Terry's release and imagines them rebuilding their relationships as one big family.

Terry hands him over on Christmas Eve and is ready to make a quick departure. However, Lisa's father, Jeff Horton (Dicken Ashworth), forces Terry to tell Jack and Vera what he has done, not wanting to be arrested for kidnap.

On 5 April 2012, Tommy learns that Jeff has died and initially refuses to go to the funeral but after Tyrone persuades him to admit that he feels ashamed because he did not really talk to his grandfather. Between them, Tyrone and Tina persuade Tommy to attend the funeral and he does. That night, Tommy realises that he is in love with Tina and vice versa. They both find each other in the street where they admit their feelings for each other and go home together. Later, Tina says that she has no regrets but Tommy regrets that it took them so long to get together. Tina says her dad would have liked Tommy and Tommy says the same but about his grandfather. Tommy suggests that they go travelling together using the money from his grandfather that he left him in his will but Tina lets him down gently, saying that she does not want him wasting his money on her.

Tommy's father, Terry, returns to the street briefly but their reunion was not pleasant - Terry punched Tommy and neither recognised the other Tyrone had to tell Tommy that his dad had just punched him. They reconciled and Terry, unlike Tina, is quite happy to take Tommy's money and persuades him to invest in a new lapdancing club that he is starting up but admits that he owes him money for the loan sharks and Tommy offers to clear those debts but only gets caught in a whole new web of dilemmas. In order to pay his debts, Tommy takes on extra jobs but he is so tired that he crashes his van and breaks his ankle. Unfortunately as he was not working at the time he was driving the van, he had to pay the pizza company for the van as it was written off landing him and Tina in more debt.

Worried about how they were going to pay their debts off, Tina took a second job doing Owen Armstrong's accounts and when she learnt that his daughter Izzy Armstrong and her partner Gary Windass, were looking for a surrogate. She told Owen she'd be interested if the price was right. Owen offered Tina £15,000 and Tina agreed upsetting Tommy and Rita. Rita told Tommy that Tina would need their help and support but Tommy could not offer her that after people learned that Tina was pregnant and assumed he was the father until he told everyone in the Rovers that Gary and Izzy are the biological parents. Tina begins to feel suffocated by the Windass family as her pregnancy progresses and is shocked when Gary tries to kiss her. Outraged by this she threatens to tell Izzy. Izzy's sister, Katy Armstrong (Georgia May Foote) finds out and lets slip the truth to Izzy, who confronts Gary after finding him with Tina. Tina tells Izzy what happened but goes into labour soon afterwards labour. Tina is rushed to hospital and gives birth to a baby boy with Tommy and Izzy present. Disgusted with Izzy's refusal to allow Gary to see the baby, Tina allows Gary to see his son, causing Gary and Izzy to argue in the special care baby unit. Tina reprimands them for their behaviour and throws them out. They reconcile and decide to name the baby Jake.

Tina starts to have doubts about giving him to Izzy and Gary. When the baby is strong enough to come out of the incubator, Izzy and Gary are shocked to find Tina holding him and Gary suggests Izzy should be left to bond with him. Tina then tells them that she has decided to keep the baby. Izzy and Gary are outraged and she promises to repay the surrogacy money leading to another row and Tina stops them from visiting the baby. They learn that they cannot force Tina to sign the adoption papers. Tina moves in with Rita. Anna, Gary and Izzy are further angered when Tina changes the baby's name to Joe after her father. After Gary tells Anna that there is nothing they can do to stop Tina, Anna storms into the pub and slaps her in front of customers. Tina asks Tommy, Rita and Dennis if she is doing the right thing. Tommy tells Tina that he will support her regardless but she must think about how Jake will feel when he is older. Izzy and Gary reluctantly decide not to fight Tina and let her raise Jake as her child. However, after she witnesses Izzy say goodbye to the baby, Tina changes her mind and decides to give the baby back to Gary and Izzy and they change his name back to Jake. Tina is devastated by this but Gary and Izzy let her continue to be part of Jake's life.

In October 2013, Tommy leaves the street after discovering that Tina moved David Platt into their flat. David then tells Tina about what happened, and that Tommy has left for the airport Tina tells Tyrone about Tommy leaving who is very annoyed considering that he is the only one working at the garage now. Tommy contacts Tyrone and tells him not to tell Tina where he is. Eventually, Tyrone tells her that he's on the Canary Islands. Tina keeps messaging and emailing Tommy wanting him back after David continues to annoy her. Tommy rings Tina, telling her that he's not coming back and that she always puts other people first, upsetting Tina.

Personality

Speaking of how Tommy was described to him Fountain said : "They described him as a cheeky chappy with a bit of swagger about him and also an eye for the ladies - and that for me was a selling point, really! I didn't get a full character breakdown until a couple of days before I started, so I learned later that he'd been busy travelling around the world and he's a bit of a free spirit. He's one of those loveable characters who can say something that's out of order but people still like him, just because he's Tommy. He's got a kind of charisma that borders on arrogance but doesn't quite cross over to that - he's quite a charming guy."

Characterisation

Asked whether he watch any of Tommy's previous scenes, Fountain said: "I didn't, but it's funny because I actually know Joseph Aston, who played Tommy when he was younger - that was quite strange, it's a small world! But I don't think Tommy was that much of a character when he was younger and he definitely didn't have any of the traits or personality that he has now - he's grown up in Blackpool, been away travelling, evolved as a person and evolved as a character. So I don't think it would have really been beneficial for me to look back, but I did look into some of the history with him and his dad and what happened there."

Speaking to The Mirror, Fountain said: "To come in as a Duckworth - one of the most recognised and celebrated names in soap, was quite daunting. Jack and Vera's are big shoes to fill and I'm just hoping I can prove to people that Tommy has that Duckworth charm and wit and gain viewers' respect." Discussing the spray tan that he has to wear for the role, Fountain confessed that he is not a fan of the beauty application. "I don't like them much," he said. "My toes look like someone's been rubbing Marmite on them at the moment - it's not the greatest look!"

Speaking of whether or not he would like Terry (Duckworth) to return, Fountain said: "Yeah, if Terry came back, I think it would cause fireworks between a lot of the characters. It would be nice to see how that would pan out, because obviously Tommy is completely different to Terry - he hasn't got so much of a temper and I don't think he's a nasty person. It would definitely be quite interesting to see what happened if Terry came back."

Departure

In August 2013, show producers discovered that Fountain had posted a number inappropriate and foul-mouthed rap videos online through YouTube, using the alias "The Phantom", which included references about rape.^[1] Fountain was suspended by the show with immediate effect, and a meeting was held with Fountain and the producers to discuss his unlikely future, in which he was informed that his contract had been terminated.^[1] Fountain then spoke out about his sacking, stating that he was "deeply sorry" and "mortified" for his colleagues and employers, and apologised for the embarrassment he had caused.

Fountain made his final ever appearance as Tommy on 13 October 2013, before his character received an off-screen departure ten days afterwards, with Tommy leaving for a new life in the Canary Islands, after his on-screen girlfriend Tina McIntyre (portrayed by Michelle Keegan) moved in her ex-boyfriend David Platt (portrayed by Jack P. Shepherd) into their flat. Fountain was then out of work for three years after his sacking, though returned to television screens in 2016.
