The walls are finally closing on Megan Walsh (Beth Nixon) in tonight’s Coronation Street, when Leanne Battersby (Jane Danson) and Eva Price (Catherine Tyldesley) find the proof to bring the child predator down.

It’s been a long time coming. For months, Megan has been grooming underage pupil Will Driscoll (Lucas-Hodgson-Wale) into an illicit relationship right under the nose of his unsuspecting family.

She exploited her status as an athletics coach and a teacher to appear beyond reproach in the eyes of Will’s dad Ben Driscoll (Aaron McCusker), stepmother Eva Price, and grandmother Maggie Driscoll (Pauline McLynn). The abuser even started a relationship with Weatherfield High’s Daniel Osbourne (Rob Mallard) as the perfect cover.

Justice comes in all shapes and sizes, and for Megan, it came in the form of schoolboy sleuth Sam Blakeman (Jude Riordan), Leanne’s adoptive son.

As Will’s friend, he sensed something was off about his dynamic with Miss Walsh and became determined to expose the monster. However, Megan fought back by sabotaging his grades in school, prompting a spiralling Sam to take unprescribed Ritalin in a desperate effort to boost his academic performance.

This would ultimately prove to be Megan’s undoing. After Sam suffered a shock collapse on the street, he was rushed to hospital where a concerned Leanne, Toyah Battersby (Georgia Taylor) and Eva finally get him to admit what’s wrong… and they were rocked to learn that Megan has been sleeping with Will.

The devastating revelation rocked the Driscolls and the Barlows/Battersbys to their core. Predictably, Megan turned on the waterworks and framed her relationship with Will as a harmless schoolboy crush that got way out of hand. While she manged to wrap her boyfriend Daniel round her little finger, Leanne is convinced that Sam was right about Megan and won’t rest until she’s locked up behind bars.

The only problem? No evidence. Megan’s been careful not to get caught. When Sam put camera in her flat to catch her out, she even staged a conversation with Will that deliberated made their relationship seem like a one-sided teenage infatuation. There’s been no dirt to incriminate this arch manipulator… until tonight’s episode of Coronation Street.

With Megan and Will sticking to the same story, Cobbles Copper Kit Green’s (Jacob Roberts) investigations hit a dead end, much to Ben’s frustration. Try as he might, Will is still insisting that Megan never behaved inappropriately and refuses to co-operate during the police interview. Megan plays the victim, with her lawyer Adam Barlow (Sam Robertson) challenging Kit to provide a shred of evidence that his client is an abuser.

Meddling Maggie does some investigations of her own and manages to find a promising lead. Will broke up with Chloe, the girl he was dating in Hull, long before he booked a room in the Chariot Street hotel for his birthday. Therefore, it couldn’t have been Chloe hiding that bathroom… it must have been Megan!

Unfortunately, Ben and Eva are thwarted when they visit the Chariot Street Hotel only to be informed by Ronnie Bailey (Vinta Morgan) that the footage has sadly been automatically deleted. Back to square one…

Incredulous, Ben can’t believe he’s hearing about this now. After all, that baby could have been his grandchild. But Eva insists she was only trying to protect him. Toyah guesses the baby must be gone by now, but Leanne suspects otherwise. Why keep pregnancy vitamins on your bedside table when you’ve already had the abortion?

Eva agrees. ‘If she has lied all the evidence we need is growing right there in her belly!’ She reasons.
