Sally (Sally Dynevor) isn't on the best terms with Tim (Joe Duttine) after discovering he concealed his health news from her, in this Friday's (January 21) hour-long episode.

Currently, Sally is in the dark about the recent revelation that her husband, Tim needs triple heart bypass surgery after some concerning test results.

However, in a dramatic turn of events next week, as Tim lies frail on his hospital bed, he pleads Kevin to speak to Sally on his behalf and convey how sorry he is and how much he loves her.

Moments before the surgery and as the anaesthetic begins to take effect, Tim hears a commotion in the hospital corridor as Sally is arrested by a police officer.

Later, Tim wakes from his operation with hazy memories of Sally's arrest and figures it must have been a dream.

In reality, Sally really was arrested after a damaging article and picture of her appeared in the Weatherfield Gazette... What did Sally do wrong?

Before these events take place, Sally will grow increasingly suspicious that Tim must be having an affair and confides in her ex-husband Kevin Webster (Michael Le Vell) about her suspicions.

Kevin encourages Sally not to jump to conclusions and instead advises her to speak to Tim directly.

However, when Sally does confront Tim and accuses him of having an affair, he still feels unable to tell her the truth about his health, which fuels her suspicions further.

Sally's worst case scenario begins to escalate when Shona Platt (Julia Goulding) tells Abi Webster that Tim has been spending a lot of time with Aggie Bailey lately.

Can Sally cope with the truth about her husband?

Coronation Street airs on Mondays, Wednesdays and Fridays from 7.30pm on ITV.
