Kathy Beale (Gillian Taylforth) and Harvey Monroe (Ross Boatman) can no longer keep their illicit secret under wraps in EastEnders next week – and it’s all thanks to, you guessed it, Cindy (Michelle Collins)!

Still bitter in her feud with Kathy, Cindy catches them in the act and decides to explode the affair at a party where poor Jean Slater (Gillian Wright) thinks she is celebrating her engagement!

Meanwhile, Suki Panesar (Balvinder Sopal) makes a discovery that could turn everything on its head.

Harvey prepares for the Slaters camping trip, but things go from bad to worse when Jean refuses to go without Stacey, upsetting Lily in the process. Harvey manages to convince Stacey to come, but his work is soon undone when Lily is adamant she doesn’t want Stacey there.

Harvey explodes and heads to the café to seek solace with Kathy, but he receives the cold shoulder. Stacey and Lily make amends and the Slaters rally together to set up a makeshift camp at home when Alfie reveals the campervan is no longer available.

Harvey is overcome with guilt and heads to the Square but when he returns home, Jean proposes…

Vicki and Ross continue to worry about Joel’s behaviour, as Vicki attempts to persuade Ross to speak to Ravi and Priya about their discovery last week.

Ross decides to speak to Avani instead, but Suki spies the conversation from afar and grows suspicious of the clandestine chat.

Gina grows concerned for Harry and later secretly reveals all to Teddy and Nicola when they accost her in the Minute Mart on his wellbeing.

Teddy and Nicola head to The Arches to share their concerns with Harry, but he dismisses them before riling at Gina.

Gina denies any wrongdoing, and the pair later make amends in The Vic where Jay warns Gina about her growing friendship with Harry.

Elsewhere, Linda is confused when Phil is reluctant to call Sharon, but he drops a bombshell and reveals she slept with Grant…

Harvey remains tight-lipped when questioned by Alfie and prepares to reveal all to Jean when she returns but things go from bad to worse when Jean mistakes Harvey’s words as an acceptance to her proposal.

Harvey makes his excuses to leave as the Slaters celebrate, and he heads to Kathy’s for a kiss but unbeknown to them, Cindy is watching and has recorded it all…

Suki’s suspicions are raised further when Avani and Ross give different versions of events when questioned about their chat, forcing Vicki to reveal to Suki that Joel slept with Avani.

Suki attempts to talk to Avani about sleeping with Joel, but Avani is in no mood to talk and storms out. Suki tries to talk to Priya about Avani, but she soon covers realising Ravi is in earshot.

Later, Suki finds a quiet moment to reveal all to Priya, but Ravi returns home mid-conversations and overhears everything. Ravi heads to No.43 to berate Joel and a fight ensues between Ross and Ravi.
