Kat found herself in business with Harvey against her will this week, after Cheeky announced that they were each other’s mystery partners in their new limo venture.

While Kat was furious about this development, she and Alfie decided to make the best of things in today’s episode – but when Jean and Mo returned to Albert Square, she panicked about this partnership being revealed.

Alfie encouraged her to come clean straight away and Kat took his advice, but when she called round and discovered that Jean was still heartbroken over Harvey, she didn’t feel able to break the news to her.

Meanwhile, organising a wedding photoshoot for their business gave Alfie ideas, and he told Linda that he was thinking about proposing to Kat – for the third time.

He plucked up the courage to suggest to his partner that they be the bride and groom in the photos and get married for real again. Kat was initially reluctant, but Alfie’s romantic speech about growing old together changed her mind and she happily accepted.

The newly engaged couple headed to the Vic and demanded that Harvey and Kathy pay for half of their wedding, which they eventually agreed to.

Kat and Alfie planned to have a big reception during the shoot next week and then wait a while before tying the knot properly. However, wedding planner Kim insisted that they have a joint stag and hen do tomorrow night to celebrate their unconventional nuptials.

As champagne flowed in the pub, Jean and Mo arrived at the Vic and were surprised to hear about Kat and Alfie’s sudden marriage plans.

With Jean confused about why Harvey knew about the engagement before her, it wasn’t long before she discovered the truth about Kat’s new business partnership.

When Kat fought back and condemned her for leaving the family during Stacey’s time of need, Jean angrily slapped her.

“You marry Alfie and change your name back to Moon,” she exclaimed. “Because as far as I’m concerned, you’re no longer a Slater!”

Is there a way back for Kat and Jean?
