The vile Harry Slater explained Harry was one of the soap's most monstrous figures Classic EastEnders Features Kat Slater Zoe Slater Share By Joel Harley Sep 2 2025 By Joel Harley Sep 2 2025 Zoe Slater and mum Kat raked up the past in EastEnders tonight (Tuesday, September 2), dredging up talk of the monstrous Harry Slater as their shocking reunion continues. Feeling tricked into seeing her mother again, Zoe wanted nothing more than to get back out of Walford. However, Kat was determined to talk to Zoe, and did her best to get Zoe to open up. As the pair swapped some difficult home truths, the reason for Zoe’s estrangement became clear. And no, it wasn’t just Kat’s poor parenting, as Zoe had claimed. Speaking of her disgust at being an ‘incest rape baby,’ Zoe’s never managed to overcome the terrible revelation that the woman she thought was her sister was actually her mum. And, more than that, the knowledge that her biological dad was her uncle, Harry Slater. But who was Zoe’s father? Harry Slater was Kat’s uncle (Credit: BBC/YouTube) Who was Harry Slater? Harry Slater was the younger brother of Kat’s father, Charlie. Unbeknownst to her dad, Harry had begun grooming niece Kat when she was a child.

Passing the second baby off as afterbirth, Viv left Luke for adoption at a convent, while raising Zoe as the daughter of herself and Charlie. Soon after the incident, Harry left the UK for Spain. The truth came out in the soap’s most iconic scene (Credit; BBC/YouTube) Return to the UK and death Harry arrived in Walford in 2001, to visit Charlie and his family. By this time, the girls’ mother had died, and the Slaters had relocated to Walford. After meeting and hitting it off with Peggy Mitchell, Harry announced his plans to emigrate to Spain along with the Mitchell matriarch. However, Kat was incensed by the news that Zoe planned on joining Harry and Peggy in Spain, and forbade her from going. During the resultant argument, the truth came out, as Kat revealed to Zoe that she was actually her mother. As Zoe demanded to know who her father was, Kat was forced to admit that she’d been raped by her uncle, Harry. Having learned what Harry had done, Charlie confronted his brother in The Vic, attacking him in front of a shocked crowd of punters. Harry left shortly after that, disowned by his family. He died from a heart attack the following year. He left Zoe £18,000 in his will but, seeing how much the money was eating Kat up, Zoe opted to burn the cheque instead. However, if the events of tonight’s episode are anything to go by, his monstrous presence still looms large over the lives of both women.
