Mackenzie Boyd and Chloe Harris’ secret finally exposed in Emmerdale with devastating twist

CHARITY Dingle has no idea she’s holding up a roof over Mackenzie Boyd’s one-night fling, Chloe Harris.

However, Mack and Chloe’s secret finally comes to light… and one Emmerdale resident is rushed to hospital.

The pair spent a night together after an argument between Mackenzie and Charity over building a family together, which followed a devastating ectopic pregnancy.

Chloe has since found out she’s pregnant with the hunk’s baby but only her mother Kerry Wyatt knew the full truth.

It’s all about to change next week as Sarah Sugden (Katie Hill) finally and unwillingly gets to the bottom of things.

The teen had initially caught on before Chloe manipulated her into thinking she was wrong.

Coming up on ITV, Mackenzie Boyd (Lawrence Robb) tries to join in Charity’s (Emma Atkins) happy banter… but he’s unable to get rid of the guilt he’s carrying.

While Chloe is happy to keep the secret, Mackenzie grows increasingly aware he needs to be honest, particularly since Charity gave the mother-to-be a place to stay when was kicked out of her home by her sister Amy Wyatt.

The following day, Mack reveals to Chloe he’ll be telling Charity about their baby.

Chloe is flummoxed as Mack refuses to back down, ready to face the consequences of his actions that same day.

But in an attempt to save her from the fallout, he encourages Chloe to leave.

She categorically refuses to be thrown to the wolves by him, knowing she has nowhere to go, and stands her ground.

Unfortunately, Mackenzie’s plans to come clean will be thwarted by Sarah who listens to their conversation again, from upstairs.

Just as Mack and Chloe get ready to reveal their secret to Charity, Sarah comes stumbling down the stairs, struggling to breathe.

Charity is mortified but manages to instruct Mack to call an ambulance as Sarah hyperventilates.

Sarah is rushed to A&E and wheeled off for medical treatment as an emotional Charity is held by Mackenzie.

The heartthrob looks over to Chloe and comes to the realisation their plan to tell the truth will remain on hold until further notice.

Charity confides in Mackenzie, worried about her granddaughter’s life expectancy.

But when Chloe clocks a doctor walking purposefully towards them, her concerns turn to fear as she knows there’s news.

As viewers of the Yorkshire-based soap will know, Sarah’s health has often been in jeopardy.

She was diagnosed with a rare genetic disease called Fanconi anaemia at the age of six, which led to her needing a bone marrow transplant.

Later on in 2017, Sarah battled throat cancer before suffering from heart failure, caused by her chemotherapy treatment.

Sarah underwent a heart transplant and gained a friend throughout the ordeal in the form of Chloe.

Could it all come to an end?
