Maggie Driscoll (Pauline McLynn) was in a complete panic in tonight’s episode of Coronation Street in the aftermath of Jim McDonald’s funeral.

Steve McDonald (Simon Gregson) received the shocking news that Jim had died earlier this month, and had sought out support from his new friend Ben Driscoll (Aaron McCusker).

Ben was more than happy to accompany Steve to the funeral, though Maggie wasn’t thrilled by the idea.

It later transpired that she had a good reason for this: She’d had an affair with Jim over 40 years ago and had kept it a secret all this time!

Unfortunately for Maggie, she had to finally face her demons when Steve and Ben returned to the Rovers with two of Jim’s old army mates in tow and one of them recognised Maggie as Jim’s lover.

However, that seemed to be the least of her worries in tonight’s episode, as the flustered landlady raised eyebrows from loved ones and punters alike with her unusually erratic behaviour.

It was son Ben who kicked off her panic when he revealed that he had missed his appointment for his heart condition due to the dire parking situation at the hospital.

Viewers will recall that Ben had a serious health scare several weeks ago and was rushed to hospital after suffering heart palpitations.

In tonight’s episode, Maggie lectured him for not taking his health more seriously, and it later became clear why she was so affected by the incident.

Having spent the day lashing out at customers, Maggie paid Steve a visit and began to question him about his dad’s diagnosis of Myotonic Dystrophy.

Steve had brought up the condition while drinking with Jim’s friends after the funeral, and it had clearly been weighing on Maggie’s mind ever since.

When Jim was diagnosed with the condition, which causes muscle loss and weakness, it caused a great deal of stress for Steve when he discovered that he had a 50% chance of inheriting it. If he had, then his children would also be at risk.

Fortunately, neither Steve nor brother Andy had the condition.

This was no comfort to Maggie, however, who is terrified that Ben may have inherited the condition.

In upcoming scenes, it is set to be revealed that Ben is actually Jim’s son, and therefore Steve’s brother.

Knowing this, it is understandable why Maggie is so concerned about Ben’s health and so keen for him to attend his appointments. But will she be able to convince him to take his health more seriously without exposing her huge secret?
