Emmerdale‘s Jacob Gallagher puts pressure on Sarah Sugden next week as he urges her to tell her grandmother Charity Dingle about her cancer.

Sickly Sarah still hasn’t informed anyone of her diagnosis, but how long before her distressing news is out?

“Just when Sarah needs her family the most, she’s shutting them out,” begins our Emmerdale insider.

“Jacob only knows because he saw her at the hospital, and made her promise she’d tell Charity. When he finds out she hasn’t, he’s fuming.”

Sarah’s condition was discovered during tests to see if she was suitable for IVF, as she’s desperate to have a baby.

While Sarah initially confided in close friend Vanessa Woodfield about her desire to become a mum, once doctors detected she had cervical cancer she vowed to deal with the upsetting news alone.

With Sarah out of sorts, Charity wonders if everything is okay and begins asking awkward questions – while Jacob finds himself dragged into the drama and has to cover for his ex, not wanting to betray her trust.

He’s angry that Sarah has gone back on her word about putting her gran in the picture, not to mention putting him in an awkward position.

“It’s getting harder for Sarah to hide how much pain she’s in,” explains our source.

“Sooner or later she’ll have to explain her symptoms to Charity. Sarah’s also banking on Jacob honouring patient confidentiality, but what if he gets so frustrated he blurts it out?”

As she anxiously awaits the next steps of her treatment, will Sarah let Charity help her?
