Dev Alahan discovers a big secret that leaves him reeling in tense Coronation Street spoiler video

Dev Alahan (Jimmi Harkishin) is left reeling in a new Coronation Street spoiler video as he discovers a huge secret.

In upcoming scenes, Gemma Winter (Dolly-Rose Campbell) comes to realise that Bernie Winter (Jane Hazlegrove) has been lying about her whereabouts, and asks Dev to investigate.

In the new spoiler video, Dev heads round to see her and asks what she’s been up to.

When Bernie explains that she has been shopping, Dev points out that he can’t see any shopping bags, but Bernie is quick to cover.

Dev makes it clear that he doesn’t believe her and begs for the truth, but when she refuses to change her story, he insists on going out to find Denny.

Denny recently arrived in Weatherfield after hearing son Paul Foreman’s (Peter Ash) interview on the radio, though Bernie was less than pleased to see him.

Things grew even more tense between them both when Denny alluded to Bernie having a secret that she wouldn’t want Gemma or Paul to find out.

With Dev halfway out of the door, Bernie finally relents, and reveals what has really been going on.

Bernie is quick to explain that she had another baby – Zodiac, or Zac for short – who ended up being taken into care.

Having never had any contact with him since, she reveals that she is determined to find him.

It was recently revealed that Bernie is set to be left worried after getting in contact with her secret son, when she fears that he may have something to do with the disappearance of Lauren Bolton (Cait Fitton).

Is she right to be worried?
