EastEnders' Teddy Mitchell makes a bold move in next week's episodes of the One soap as his son Harry drops a hint about their past. After Gray Akins sells One Albert Square, Chelsea Fox is forced to move out of her home to number 20, but the new owner is revealed to be Teddy. He tells half-brother Billy Mitchell and Honey that he's brought the property sparking the couple to explain how previous owner Gray killed his wife Chantelle and Tina Carter in the house.

But Teddy is unfazed by the revelation but his clueless son Harry makes a tactless remark to furious Chelsea. He is forced to march Harry around to number 20 to apologise as he reminds Harry of the trouble they've left behind and that they need to make friends in Walford. He suggests they host a housewarming party and invite their new neighbours.

Teddy starts inviting people to his party and even manages to get Kim and Chelsea on side with his charm offensive. While the party is in full swing, Chelsea is stunned when Teddy reveals he insisted on an last-minute clause in his deal to buy Gray's house. Harry sidles up to Teddy and tells him that 'you know who' has been sniffing around their old place to find out where they've moved to.

But Teddy shrugs the comment off and insists he's got everything under control. But who is the mystery person that is looking for Teddy? Since Teddy and his sons Harry and Barney arrived on the Square, little is known about their past except they are related to Billy though Stevie Mitchell.
