Hollyoaks finally confirmed who had been blackmailing the McQueen family during Thursday's E4 episode - and it was a major shock.
Theresa McQueen had been faking her concern the entire time, as it was revealed she was one of the blackmailers against her own family, conning money out of them over their secrets.
But she wasn't alone - as returning character Seth Costello was also confirmed to be against the family in a twist no one saw coming at all.
Miles Higson made his comeback to the Channel 4 soap, reprising the role nine years after his big exit for the shocking twist.
It turns out the pair are now an item, and have been trying to con her own family out of money for their new life together.
What she doesn't know though is that there is one more person working with them.
Seth's evil grandfather Silas Blissett, who has a history with the family and Mercedes, is helping Seth - or really it's the other way around.
Theresa doesn't know this though, and despite Mercedes knowing Silas is behind it after a recent phone call no one believes her.
As far as Theresa is concerned, she and Seth are plotting it all - so how will she react to the truth?
Viewers learned the shocking twist of events on Thursday, while the family are yet to uncover what is going on.
As the episode played out, suspicions over Theresa's involvement were confirmed - as some viewers had predicted she might be helping Silas.
But what they did not see coming until the scenes aired was that Seth was back, and involved.
Suddenly, the truth came out on screen sending fans into meltdown as Theresa and Seth confirmed what they were up to.
It's not yet clear when the family will find out, and when Theresa will realise who else is in on it!
Hollyoaks airs weeknights at 6:30pm on Channel 4, with the next episode at 7pm on E4.
