Coronation Street‘s Cassie Plummer is set to discover a concerning secret granddaughter Hope

Dobbs has been keeping.

In scenes set to air tomorrow (September 13), youngster Hope takes a drag on her vape in the school

corridor, refusing to listen to Jack Webster and Sam Blakeman, who both try to warn her about the dangers of vaping.

Later, Cassie discovers the vape pen in Hope’s school bag and confronts her about it. Hope begs her grandmother not to tell her parents – but will she keep her secret?

The family has a lot on their plate at the moment in the ITV soap, with love in the air for troubled Cassie as she harbours a crush on Steve McDonald.

Cassie has feuded with Steve’s estranged wife Tracy Barlow. However, as Tracy leaves the cobbles to give her relationship with Tommy Orpington another try, she plays matchmaker and points out to Steve that Cassie likes him.

Steve has had multiple failed dates since Tracy left him – so could this be his happily ever after?

Elsewhere, Hope’s father Tyrone is set to go to drastic measures to attempt to stop his ex-partner Alina Pop and their son Dorin from returning to Romania.

Alina arrived back in Weatherfield to testify in a human trafficking trial, with Tyrone discovering that the former lovers share a son.

Now that the gang members behind the crime are behind bars, Alina feels safe enough to return to Romania, but Tyrone secretly steals her passport from her rucksack to spend precious time with Dorin.

Fiz, disturbed by Tyrone’s actions, returns their passports but doesn’t give away Tyrone’s plans, and Alina and Dorin leave the country as planned.

But when Alina abruptly ends a video call between Tyrone and Dorin claiming that the contact is too upsetting for her son, Fiz complains that she never would have returned the passports if she’d known Alina would behave like this.

Suddenly, Fiz and Tyrone realise the call is still connected and Alina heard their entire confession about her passport being stolen.
