Hollyoaks spoilers follow from Monday's episode on Channel 4 streaming, which doesn't air on E4 until Tuesday.
Ella Richardson has made a damning discovery about father Warren Fox in Hollyoaks.
The teen recently learned that Warren is her long-lost biological father, though their relationship has been routinely tested by Warren's initial refusal to accept that he's her dad.
Meanwhile, Warren has been tied up in an affair with Mercedes McQueen while his best mate Felix Westwood has been away in treatment for his mental health.

Felix has since returned to the village, leaving Mercedes and Warren to suspect he secretly listened to them talking about their fling in recent scenes.
What to Read Next
In Monday's (October 23) streaming episode, Mercedes was filled with dread about her 40th birthday party — especially since she realised Felix wasn't returning her calls of a sudden.
Mercedes and Warren rushed to figure out whether Felix may be in trouble, only for him to walk right up to them to give Mercy a big kiss for her birthday.
This only caused Mercedes to panic even more, as she pointed out to Warren that if it wasn't Felix who'd overheard them, it must have been someone else.
It didn't take long for the truth to come out as Ella turned up to speak with Warren as he put up decorations for Mercy's party. Warren made it clear he didn't have much time to talk.
"That's a nice way to talk to your daughter. I bet you don't talk that way to the woman you're having an affair with," Ella shot back.

Warren warned Ella not to play game with him, leading her to admit that she didn't actually see the woman her father had been speaking to.
"You need to forget about what you heard last night," Warren insisted.
Ella revealed she'd be coming to the party later on, since her dad wasn't in "any position to overrule" her. As the party got underway, Warren stunned everyone by announcing he'd be cutting Mercy in for 10% of the garage's earnings.
As the two spoke privately (or so they thought) later on, Warren explained to Mercy that Ella had been the one listening in on their conversation — but she didn't know it was Mercedes he'd been speaking to.
Unfortunately for Warren, Ella happened to be listening in once again, only this time she knew unequivocally that he'd been having an affair with Mercedes!
