“Sarah’s already proved she’ll kill for those she loves,” begins our Weatherfield source. “This is a desperate move that could add years to her sentence, but she needs to show she’s not to be messed with. It’s survive or die in there, and Sarah is learning the hard way…”
Sarah’s time in prison is getting worse by the day, with Kacey’s threats and violence making her life a living hell. Furthermore, her relationship with Kit is in tatters, and she now feels as though she’s abandoned her son.
Knowing that Kit is struggling to cope on the outside, Sarah’s concern turns to Harry’s welfare. But despite Bethany trying to reassure her that everything is okay, a guilty Sarah is heartbroken for her boy.
When Kacey enters Sarah’s cell, she finds the locked-up mum in floods of tears, but she’s not there to offer sympathy. Sarah soon goes cold with dread when Kacey asks a simple question, as it becomes apparent that she knows Harry’s name.
“Sarah hoped Kacey’s threats were empty,” explains our insider. “She thought that as long as Harry was being well looked after at home, then he’d be able to cope without her. Now that she knows that Kacey has influence on the outside, Harry’s in real danger!”
Back on the cobbles, Sarah’s oblivious family do their best to pretend that everything’s normal. Bethany is concerned when she finds blood on Kit’s shirt, while Alya and Adam take Harry to a new friend’s house – but they are unaware of the danger that lurks…
