The drama begins when Lloyd (Craig Charles) has a chance meeting with a former flame named Mandy in an upcoming episode.
Lloyd is delighted to have the chance to catch up with Mandy (Pamela Nomvete), as he's always thought of her as 'the one that got away'. However, while he is keen to have her back in his life again, Mandy seems hesitant to revisit the past.
When Lloyd persists with Mandy and pops round to her house, he is stunned to see that she has a daughter named Jenna (Krissi Bohn), who she had failed to mention in their earlier meeting.
Back on the cobbles, an intrigued Lloyd tries to work out how old Jenna is. With the dates matching and Mandy's sketchy behaviour speaking for itself, Lloyd realises that Jenna could be his.
Confiding in Eileen about the full story, Lloyd explains that he'd always been keen on Mandy, but his best mate Johnny got in first and married her. Johnny - who has since died - wasn't the best of husbands and for a while Mandy turned to him for comfort, leading to an affair.
When Lloyd confronts Mandy with his suspicious over Jenna, she instantly dismisses them. However, Lloyd can't let this go - convinced that he is right.
In the end, Lloyd heads back to Mandy's place, leading to an awkward atmosphere as Jenna is present once again.
Jenna soon realises that something is amiss, and when she learns that her mum had a fling with Lloyd, she immediately has questions of her own to ask!
Having always thought that Johnny was her father, how will Jenna react when she learns that her dad is actually Lloyd?

Tyler (Tony Discipline) is in for a shock as he arrives back on Albert Square, finding out that his brother Anthony is missing and that Derek now owns the antiques emporium.
Keen to repair his fractured relationship with Joey (David Witts), Derek has given him the keys to the Moons' former workplace, telling him that he can turn it into any business he likes.
Joey is still reluctant to build bridges with his father, though, so he tells Tyler that they should team up to teach Derek a lesson after what happened to Anthony.

Joey is not at all impressed when Tyler takes up Derek's offer. Tyler assures him that it's just a business arrangement, but when Joey calls him Derek's lapdog and insults Anthony, Tyler punches him.
