Aiden is the son of John and Angela Longhurst, brother of Valerie Longhurst (13), and younger half brother of Matthew and Adam Longhurst. His father was an abusive man, who regularly beat his mother - and already had prior domestic abuse convictions regarding his first wife, Valerie (Matthew & Amanda's mother). He grew up believing that the appropriate way to treat women was with disrespect and violence, adoring his father despite his faults - it was all he ever knew.
In November 2008, Aiden's mother Angela made contact with Adam and Matthew - John's children from his first marriage, seeking out support from other family members as her family did not support her at all. While John didn't mind her desire to talk to Matt, he refused to acknowledge Adam (born Amanda) as family - and once he discovered Angela had been in contact with him, made his opinions very clear in the kitchen. He was afraid that Angela was seeking support to leave him, and they had an argument that ended in Angela's death and the two children witnessing the entire gory scene. The children were immediately rushed to Narrie, and left with Matthew while a police investigation arrested John, and had him sentenced for life.
Aiden and Valerie then lived with their elder half-brother Matt and his new wife Kate, at the apartment on the top floor of the Drunken Roo, the pub that Matthew owned and managed. Aiden was enrolled in Tallygarunga's junior school, and the school has been his one stable home since then.
When Matthew was hit by a tram and subsequently fell into a coma in 2012, Matt's brother Adam took custody of both Aiden and Valerie. They live in a small house in the outer-suburbs of Melbourne to be close to Adam and Cass's workplaces, but both Aiden and Valerie spend the majority of their week at Tallygarunga. Adam and Cass make plenty of time for them during holidays and weekends, often including Matt and Kate's daughter Hazel in family time.
Aiden does love the school and has slowly grown into a respectful young man. He has his sights set on a future in the medical profession, wanting to be the one who can stop tragedy from happening to other families.
Aiden knows what happened to his mother, and still has horrific dreams about it. He's glad that Valerie was too young to remember any more detail, and tries his best to shield her from the brutal truth.
