The pair look set to grow closer as Ray attempts to comfort a lonely Denise (Diane Parish) in early January, but it's clear that they're playing with fire.
Viewers see the drama begin when Kim and Zainab plan a surprise dinner party to cheer Denise up, feeling sorry for her after she struggled with being single at Christmas.
Hoping they can bring some romance into Denise's life, Kim and Zainab invite AJ Ahmed and Ian Beale over as potential suitors. However, when the meal doesn't turn out well, Denise is left feeling worse than ever.
Ray (Chucky Venn) notices Denise's downbeat mood and tries to reassure her, but it's not long before their heart-to-heart leads to a passionate clinch.
Will this be the start of something, or is it just a one-off mistake?
EastEnders airs these scenes in early January on BBC One.
