EastEnders has finally revealed the dramatic way in which Kathy Cotton and Harvey Monroe’s secret affair comes to light — and it’s every bit as explosive as fans might expect. After months of sneaking around behind Jean’s back, the couple’s deception is brought to a screeching halt when they are caught on camera, exposing their betrayal in the most public and undeniable way possible. Harvey, who had been torn between guilt and desire, had recently decided that he could no longer continue living a lie. He resolved to come clean to Jean and commit to Kathy fully, believing that honesty was the only way forward. But before he could make his confession, fate intervened in the most humiliating fashion. The footage that surfaces leaves no room for doubt, and the fallout from the revelation is set to rock Albert Square as characters scramble to process the truth — and Jean faces the heartbreak of betrayal from two people she trusted.

But as he went home to confess everything, Harvey got a big shock when Jean got down on one knee and proposed to him.

In today’s episode, Harvey was stunned and was unable to give Jean an answer, so she ran off in tears.

Harvey faced questions from Alfie about what just happened, and when he expressed doubts about his relationship with Jean, Alfie reassured him that he was good enough – even crowning him an honorary Slater man.

Meanwhile, Kathy found a devastated Jean in the café and assumed that Harvey had come clean, but Jean revealed that she had asked Harvey to marry her.

Jean opened up to guilty Kathy and said that she felt Harvey doesn’t love her anymore, even blaming her bipolar disorder for him getting cold feet.

With Kathy advising her to get answers from Harvey, Jean returned home to have a proper chat about their relationship status.

Harvey told Jean that he can’t marry her, but when Jean broke down in tears about how she is struggling to keep the family together, he vowed to support her – which Jean mistook for him accepting her proposal.

The couple told Kat, Alfie, Lily and Freddie that they had agreed on a long engagement – but as the family celebrated, Kat looked suspicious of Harvey.

Harvey called round to see Kathy and updated her on what had happened, with Kathy left disappointed that he had ended up saying yes.

He made it clear to Kathy that it was her he loves, but they needed to end their affair, in fear of the damage it would cause if Jean found out.

However, what they didn’t realise was that Cindy was secretly filming their covert chat, and even got footage of them kissing.
