Jack Branning (Scott Maslen) has uncovered an unsettling secret about Harry Mitchell (Elijah Holloway) in EastEnders.
Ever since Harry arrived with his family – dad Teddy (Roland Manookian) and brother Barney (Lewis Bridgeman) – fans have been trying to piece together the mystery of why they made a sudden move to Walford.
We know that the lads are estranged from the matriarch of their family – who will soon be heading to Albert Square.
Harry swanned into Walford – and instantly caught the eye of Jack’s daughter Penny (Kitty Castledine).
The two men clashed over what was best for her, and eventually came to blows last week after it was revealed that Jack had been blaming the wrong person for the club crush at Peggy’s.
