Joel reconciled with his dad Warren Fox last year, who currently has no idea of Joel’s involvement in sister Katy Fox’s death.
Katy died from a drug overdose, after Joel gave her a bad batch of heroin, but he told his dad it was Bart who supplied the drugs.
Since Katy’s death on Hollyoaks, Joel has remained off drugs and turned his life around, turning to the church and training to become a priest.
But Joel is now struggling to come with Bart’s death, and last month he fled the village to get away from his dad.

Joel returned this week, but it’s clear he’s hiding something.
In last night’s E4 episode of the soap, Joel broke down as his dad pleaded with him to hide his killer secret.
As things got too much for him, Joel did something that left fans seriously worried.
Towards the end of the episode, Joel was seen meeting with a mystery person down a dark alleyway.
He the shook hands with the guy, before appearing to take drugs from him.
Has Joel relapsed, or is there another explanation?

Viewers will have to stay tuned to find out whether Joel will turn back to drugs, with a horror accident also on the cards.
But fans took to Twitter begging him not to take heroin, with one viewer saying: “Nooooo! Don’t do it Joel!”
Others hoped his return would see him finally get together with Cleo McQueen, with neither character sharing their feelings.
This could change though, as next week Cleo is set to finally tell Joel she loves him – but will the accident tear them apart?

Meanwhile, a new clip teased Warren trying to make amends with his son before telling him he didn’t look well and could be coming down with something.
How long can Joel keep his secret from his dad, and will Warren find out about the drugs as Joel prepares to meet up with the mystery man again?
