Towards the end of 2009,
Holly Barton (
Sophie Powles) starts
flirting with
Aaron Livesy (
Danny Miller) and it looks like a relationship is brewing. At first, Adam isn't keen but comes around, making friends with Aaron. When Aaron suddenly starts playing hard to get with Holly, Adam questions it, but Aaron says it's all part of the plan. However, everything slots into place when the boys and Holly go on a "lads" night out. When Aaron and Adam are on their way back, they are involved in a car crash and Aaron cuts his head. As Adam is checking it out, Aaron leans in for a kiss. Adam is horrified and pulls away, questioning Aaron's sexuality, but Aaron convinces him that it's all in his head. Not completely convinced, he tells Holly after realizing that she has slept with Aaron, but his parents insist he drops it when Holly, refusing to believe Adam, gets annoyed with him. Aaron watches jealously as Adam gets closer to
Scarlett Nicholls (
Kelsey-Beth Crossley) and starts dating her. In early 2010, Adam is still convinced that Aaron is gay, but leaves Aaron alone as he learns that Hannah is being bullied, but is confused about why
Victoria Sugden (
Isabel Hodgins) did it. When sheep on the Barton's farm start being stillborn, John knows something is wrong but doesn't know what. When
Carl King's (
Tom Lister) children,
Thomas (Jack Ferguson) and
Anya (Ceryen Dean), are hospitalized,
Jai (
Chris Bisson) and
Nikhil Sharma (
Rik Makarem) are blamed but tests clear them and Adam remembers moving some toxic barrels a few months back and is shocked to discover he's responsible. When he confesses to his parents, John goes mad but realises that they have to admit responsibility. They are fined by
Nathan Wylde (
Lyndon Ogbourne) for the cleaning up, so John stops Adam's wages until the bill is paid. In April, Adam witnesses Aaron kissing his secret boyfriend,
Jackson Walsh (
Marc Silcock), but tells Aaron that he'll still be his mate, regardless of his sexuality, and keep his relationship secret. On his birthday, Adam and others at The Woolpack see Aaron punch Jackson, after Aaron thinks he's flirting with him in public, resulting in Aaron being arrested. When released, Aaron decides he can no longer risk people finding out he's gay and attempts suicide in the garage. When Adam and
Cain Dingle (
Jeff Hordley) discover him, they save him but Aaron reveals that he wishes he had died. Adam and his whole family struggle to come to terms with his sister Holly's
addiction to heroin. He takes her to see Jackson who, after a horrific accident, has lost his ability to walk. Adam tries to show Holly that, she (unlike Jackson) can choose to get better, and she has made herself ill. The message doesn't sink in and Aaron is annoyed with Adam for using Jackson to get this message across to his sister. Scarlett notices that Adam has less and less time for her, ignoring her phone calls and text messages. This decline in their relationship culminates in Adam kissing
Mia Macey (
Sapphire Elia) on New Year's Eve. Devastated by this, Scarlett leaves for a holiday in Canada. Adam tries to pursue Mia, although she plays hard to get. They later start a relationship although Adam ruins this when he starts an affair with Mia's mother,
Ella (
Corrinne Wicks). She is furious when she finds out the truth and leaves the village. Adam is understandably distraught when he learns of his mother's affair with Cain, but he is delighted when John and Moira patch things up and they get back together. When John and Moira spend the night in a hotel, Adam is stunned to receive a phone call from
Katie Sugden (
Sammy Winward), informing him that John and Moira have been in a car accident. Shortly after arriving at the hospital, Adam watches in horror as the doctors declare his father dead. Adam falls to pieces after the death of John, blaming Cain for his death, believing that if Cain had not seduced Moira, his parents would have never split and had to go on the romantic break, resulting in John's death. Adam then set fire to the Dingle Automotors Garage, trapping Cain inside, then saving him. Adam confides in Aaron. Seeing Adam's pain at the grieving of John, Aaron tells the police he started the fire. Missing court, Adam helps Aaron escape to France with
Ed Roberts (
Lloyd Everitt). In August 2014, Adam is shocked as Aaron returns two years later and is ready to cover for Adam, following events of the fire at the garage. Aaron confesses to arson for Adam, but Adam later clears his name and spends a while in prison. During his time there, Adam suffers a beating, but recovers in hospital and is later released from prison. Adam and Aaron set up a small scrapyard business nearby.
Emma Barton sabotages them early on and things nearly end in tears when Aaron is hardly attending work, but the two friends continue to make it work. In March 2015, Adam proposes to
Victoria Sugden on her 21st birthday. Victoria accepts, but later admits that she is not ready for marriage and lets Adam down, leading to the pair breaking up. Adam sleeps with
Vanessa Woodfield, who later becomes pregnant, but the father is unknown. Eventually, results reveal that Adam is the father, when really the actual father of Vanessa's baby is
Kirin Kotecha. Adam and Victoria elope to get married, following Victoria's accidental knock down of
Ashley Thomas, who is hospitalized and diagnosed with
epilepsy. Adam and Victoria marry on the day of Victoria's court hearing, and she is given a caution for accidentally running Ashley over. In late July 2015, Adam and Victoria return from their honeymoon and focus on their life as a married couple, but it is interrupted by the existence of Adam's unborn child, as it is still believed that Adam is the father. Adam fails to arrive at Vanessa's scan, which angers her and she makes the decision to leave Emmerdale because she does not want Adam involved in the upbringing of Vanessa's baby. In August 2015, Adam considers him and Victoria leaving instead to start a new life, but Victoria thinks Adam is mad thinking of leaving. Adam gets grief from
Rhona Goskirk and he gets drunk, rather than attend the wedding of
Pete Barton and
Debbie Dingle. Adam falls asleep in a car at the scrapyard, but is unaware that a fire had been started, which then caused some gas canisters to explode and collide with a helicopter, which then crashed through the roof of the Village Hall. Adam wakes up in the car and Robert and Chrissie get him out before the car explodes. In January 2016, Vanessa takes another DNA test to see if Adam really is the father of Johnny (Vanessa's baby), after she finds a
birthmark which the midwife says that it is perfectly normal for a mixed-race baby to have. The DNA test reveals that Kirin is actually the father. When Vanessa breaks the news to Adam, he is devastated and attacks Kirin's father after he learns that it was him that switched the DNA results. Vanessa gives Adam some time alone with Johnny, but Adam takes off with him and hides in a hotel. Victoria talks Adam into returning Johnny to Vanessa before it gets serious. In February 2016, after learning that Aaron had been repeatedly raped at the hands of his father when he was younger, Adam is livid and offers to help Cain deal with Aaron's dad. After Aaron returns from giving evidence at the police station, he hugs him and apologizes for not being there for him. In March 2016, Adam left shocked to found out that Holly returned to the village after 4 years away. A month later, Adam supports Aaron through the court case where Gordon is found guilty and sent to prison. A few weeks later, Adam celebrates with the rest of the family when Aaron gets his deed poll letter officially declaring him as a Dingle. In September 2016, Adam is heartbroken by the sudden loss of his sister Holly, who died from a
heroin overdose. He and Victoria move back to Butlers to support Moira. On the day of the funeral, Adam is angry and upset that his sister Hannah is unable to attend and comforts Moira as they say their final goodbyes to Holly. The following week, Adam helps Robert pull Aaron out following a motorway collision and Adam went to the ambulance with Aaron who later survive. Later, on the same day, he is devastated when James dies as a result of the same accident. On the day of James' funeral, Adam tries to put a brave face on everything, insisting to Moira that he has already buried his dad. However, when Ashley interrupts the service Adam gets upset and asks Laurel to take her husband out, saying he's ruining his dad's funeral. Adam is surprised to learn that James has left him an equal share in his will much to Ross' displeasure. They clash over the issue and Adam admits he was not going to take it but changes his mind and decides to accept it. Adam fights with Ross after he learns that he tried it on with Victoria. Victoria tries to break them up but ends up getting hurt. She is taken to the hospital where she tells a shocked Adam she might be pregnant. The test comes back negative, but Vic confides in Finn that she wants a baby and she's not sure how Adam feels. Later at Butlers, Victoria tells Adam she wants a baby and Adam concedes that if that is what she wants then they will start trying. The next day, Adam confides to Aaron his doubts about starting a family after his experience with Johnny. Aaron assures Adam he's already proven he'll be a great dad and offers to babysit for him anytime. Later, Ross apologizes to Vic and Adam for his earlier behaviour and they call a truce. Adam tells Moira that he and Victoria are trying to start a family and she is delighted. In February 2017, Adam helps the Sugdens and the Dingles organize Robert and Aaron's impromptu wedding. The next day, Adam is gutted when Aaron is sent to prison for 12 months on a GBH charge. However, he is released two months later much to Adam's joy. That year, Victoria and Adam try to conceive a baby, but Victoria fails to get pregnant.
Diane Sugden (
Elizabeth Estensen) pays for a private
fertility clinic, where it is revealed that Adam has zero sperm count. The couple is devastated and begin to fall out. Adam kisses Vanessa during a moment of weakness, leading to Victoria breaking up with him. ==Reception==
