It's the unmissable moment that EastEnders fans have been waiting for - Ian Beale discovering that his mum Kathy is alive and well.
Adam Woodyatt and Gillian Taylforth filmed the must-see scene on location in London today (August 5) and newly-released pictures offer a tantalising sneak peek.
Future episodes of EastEnders will see Ian reach breaking point as the pressure of concealing his young son Bobby's killer secret takes its toll.

Jane tries to talk Ian to safety
Seemingly seeing no other way out of his desperate situation, Ian prepares to take his own life by jumping from a bridge at the Queen Elizabeth Olympic Park.
Ian's wife Jane desperately tries to prevent him from doing the unthinkable, but nothing can prepare either of them for the shock they face when Kathy arrives on the scene.

Ian finally comes face-to-face with Kathy
Kathy was at the centre of one of EastEnders' biggest ever surprises in February when she briefly reappeared in the show's 30th anniversary week, despite her off-screen 'death' in 2006.
Since then, Kathy has made another brief appearance by meeting up with her ex-husband Phil Mitchell in a café.
Ian and Kathy's dramatic reunion scenes are expected to hit our screens in early October.
