The character made his first appearance on 30 November 2001 when he was born to established characters Leah (Ada Nicodemou) and Vinnie Patterson (Ryan Kwanten). From his introduction, VJ has been played by eleven different child actors. These include Carlo Teodorowych, Jack Monger, Max Theoharis, Marcus Spinetti, Jack Riddle, Harry Roberts, James Roberts, Nicholas Stevens, Cameron Stevens and Cooper Scott. Felix Dean was cast in the role in 2007. Nicodemou viewed Dean as a "surrogate son" and felt the same way that Leah does for VJ. She has also stated that she became attached to each actor that has played VJ.
In May 2014, Nicodemou confirmed that the character had been recast once again. Dean finished filming earlier in the year, while VJ went off-screen for a while. Of the new actor, Nicodemou explained "We've got a new bloke, Matt, who's started in the role. He is really lovely and eager. I think he's going to be really, really popular as well." The actress added that VJ would be all grown up when he returns, as the producers wanted him to look older. On 31 August 2014, it was confirmed that Matthew Little had taken over the role. Little was cast shortly after he completed a brief stint in rival soap opera Neighbours. He said, "I was facing unemployment and literally got the call, so it was a relief to be offered another job to be honest."
Early storylines for VJ were developed through his mother, Leah's relationships. His father, Vinnie is sent to prison and meets his old friend Jesse McGregor (Ben Unwin). Vinnie convinces Jesse to go to Summer Bay on his release and look out for VJ and Leah. Nicodemou told Jason Herbison from Inside Soap that Leah thinks Jesse is a reformed character because Vinnie would not have sent him to stay otherwise. Leah grows close to Jesse following the death of Vinnie in a fire. VJ begins to choke and Jesse saves his life and subsequently Leah kisses him. The actress told Herbison that Jesse forms a bond with VJ which makes him an ideal partner. Jesse helps Leah through problems with VJ's hearing. Following a break-up, Leah learns that VJ will become permanently deaf unless he has another operation. Jesse acts as Leah's "rock" throughout VJ's health issues and Leah wants to reconcile their relationship.
In early 2009, VJ was kidnapped by Brian Lawler (Ric Herbert), who was desperate to get his hands on Leah's inheritance. VJ was playing with Jai Fernandez (Jordan Rodrigues) and Annie Campbell (Charlotte Best) when he went missing. When Leah started looking for him, she was not initially worried, until she got a phone call from someone asking for a ransom of $25,000. Leah was not aware that the kidnapper was Brian, until she went to hand over the money. Nicodemou revealed that VJ was in "a lot of danger" and Leah did not know if he was okay. When she met with Brian, she saw VJ in the car, but Brian had a police radio and when he heard there was a call-out, he drove off with VJ. Leah was hysterical and thought that since Brian had the money, why would he come back with her son? Brian was eventually apprehended by the police and VJ was reunited with his mother.
Leah begins a relationship with Miles Copeland (Josh Quong Tart) They keep it a secret knowing that VJ is still close to her ex-boyfriend Elijah Johnson (Jay Laga'aia). Nicodemou told a writer from Inside Soap that VJ and Miles get along "really well" and he plays a "great father figure" to VJ. Leah does not want to ruin their friendship. VJ discovers the truth but chooses not to tell Leah. When Leah does admit to being with Miles, VJ reveals that already knew and has "major reservations" about their relationship. The actress said that Leah has been a struggling single mother since VJ was born. "As a result, the poor boy's had to grow up so quickly. He's very protective of his mum, so any man coming into their lives is going to have to prove himself worthy - even Miles." Leah later discovers that she is pregnant. But VJ is unhappy with the development and voices his concern. Nicodemou told the writer that Leah and Miles are worried because VJ is unenthusiastic about her pregnancy. She explained that VJ has "seen his mum go through a lot over the years, and isn't sure that they're ready for this just yet." VJ is "devastated" when Leah and Miles break up and he blames his mother. When Miles notices that VJ is struggling to cope with the changes, he tries talking with him, but VJ ends up hating his mother even more. VJ tries telling Leah how he feels, but when she refuses to listen, VJ packs a bag and runs away from home. A show spokesperson told Susan Hill from the Daily Star, "Leah has been through a lot these past few weeks and has not realised just how badly VJ has reacted to her split from Miles. When she notices he's gone she is beside herself with worry. She realises how selfish she's been and is desperate to find the lad before anything happens."
On the day VJ is born, his father Vinnie is arrested for fraud and later stands trial. Vinnie is found guilty and sentenced to 18 months' imprisonment. VJ's mother Leah struggles to raise him despite assistance from VJ's uncle Alex Poulos (Danny Raco).

For his portrayal of VJ, Dean has been nominated for Best Young Actor at the 2008 and 2009 Inside Soap Awards. VJ's name has been a source of amusement to some critics, with one calling him "unfortunately named" and another believing that he was named after an "early model Holden". Linda Barnier and Ben Doherty from the Newcastle Herald wrote that they understood his name to be short for "Video Disc Jockey", while the Sun Herald' Brian Courtis thought he had been "sensitively named". When VJ wanted to become a River Boy, Jaci Stephen from the Daily Mail proclaimed "The days when VJ never uttered a syllable (he was only ever just this side of rigor mortis) are long gone".
Stephen later wrote "If ever there was a child who had 'Bully me' tattooed on his forehead, it's VJ – he's just been too mollycoddled by his mother." When VJ named Jett as his bully, the reporter thought that the gesture would not make him popular at all. During Leah's pregnancy storyline, Stephen quipped "As if being called VJ were not bad enough, on Monday the boy is less than happy to discover that his mother is pregnant. To him, she must be about 103 (certainly it feels like that to me), so who can blame him?" Stephen also thought that "VJ is more appealing than his mum". Gary Gillatt from Inside Soap bemoaned VJ's 2014 recast, saying "Are we really supposed to believe these Summer Bay 'kids' are the same age? VJ now looks about 10 years older than Jett!"
