EastEnders newcomer James Farrar has revealed more about his character's past ahead of his arrival in Walford next week,
Zack Hudson was recently confirmed to be the secret brother of Sharon Watts, and the son of villain Gavin Sullivan.
Evil Gavin was killed off on the soap off screen last month, leading to Sharon making the discovery.
He's already caused some trouble and there's more on the way, with actor James revealing Zack's trauma over his past.
Hinting he could have traits inherited from his villainous father, James revealed Zack just wants to be part of a family with his sister.
Speaking to The Mirror and other press, he said: "There’s trauma certainly and seeing as nobody knows him it is hard for Zak to fit in, in that he finds it easy to impress with his charisma but makes so many mistakes because of his upbringing.
"I don't know masses about [his past] yet but there are certain scenes Tish and I have shot that show there are reasons behind the way he acts, when he acts in an ignorant way.
"But the majority of the time he’s a nice guy."
James also teased more drama ahead as he revealed: "Up to this point, we've had one stunt in my arrival episode and we've had four since.
"They might be fights, or trauma – I will leave that open. He ruffles feathers, let's say that."
On whether Zack will be like his dad, James hinted there could be more to him.
James said: "He's smooth, but his behaviour has consequences. He's already delved into his past with Gavin and the mistakes he makes are due to either the way Gavin treated him, or the fact you do turn into your parents.
"Zack is desperate for Sharon to embrace him.
"It soon becomes clear that he needs to stop making mistakes though, because even though they might be innocent, Sharon will always see them as Gavin all over again."
EastEnders airs Mondays and Fridays at 8pm and Tuesdays and Thursdays at 7:30pm on BBC One.
