A cheating scandal is revealed.

Hollyoaks spoilers follow for Monday’s episode (September 23), which is available to watch now on streaming service Channel 4 and hasn’t yet aired on TV.

Hollyoaks has confirmed the father of Leah Barnes’ baby in the show’s latest episode.

In last week’s episodes, after the show jumped forward a year in time, it was revealed that Leah was heavily pregnant.

Shortly after, she gave birth to a baby boy, just as her dad Ste was brought round from his coma.

Leah told Ste that she was leaving for university in America and was planning on putting her baby up for adoption – but gave Ste the option to look after him instead.

But what hadn’t yet been revealed was who the father of Leah’s baby is, although Leela and Nancy suspect that it is Charlie, who Leah became close with.

In today’s episode, Rex paid a visit to Ste in hospital. Ste pretended to be friendly with him, but he secretly hid a syringe under the duvet.

Rex explained that he found out Grace is his sister, and that when he was younger, his dad Fraser asked Dave to look after him.

He made it clear that Dave was Blue, but Ste thought that Rex helped him to plant the car bombs and proceeded to attack him with the syringe.

Rex was fending him off when Leah entered the room, and she assumed that Rex was attacking Ste instead. However, Rex made up a cover story and didn’t reveal that Ste was trying to kill him.

Leah told Ste that social services were arriving today to give her baby to the adoptive parents and gave him one more chance to change his mind.

But Ste remained firm that he couldn’t look after her baby and said he deserved a proper family, leaving Leah upset.

Tony came to the hospital to give Ste a pep talk and reminded him that he has never given up on his family before.

As Leah was handing over the baby, Ste burst in and told her that he was able to take on the responsibility.

At that point, Leah spotted Dillon and told him that Ste was going to take the baby, which left him horrified, as he is the father.

“If Lucas ever finds out what we did,” Dillon said, “I will never forgive you” – confirming that he cheated on Lucas with his boyfriend’s sister.

Will Dillon manage to keep this huge secret, or will Lucas find out the truth?

Hollyoaks airs on Mondays-Wednesdays with its Channel 4 streaming premiere at 7am, then an E4 broadcast the same night at 7pm. Full episodes are also released on YouTube a week after their Channel 4 release.
