Warning spoilers ahead!
Viewers of EastEnders know that Ian has been struggling to keep his liaison with Rainie Cross on Good Friday a secret, even lying to the police about where he was the night Lucy died.
But, following an emotional plea for information on her murder, Rainie is back and blackmailing him for more money.
According to reports, Ian later loses it and confesses all to Phil Mitchell – but he doesn't get the reaction he was expecting.
Fans of the BBC One soap will know all about Phil's history with Rainie, and that she was the one who previously got him hooked on crack.
Phil offers to sort Rainie out for Ian, but we all know what it means when a Mitchell is out for revenge.
Just how far will Phil go to silence Rainie and keep Ian's secret.
His family are not strangers to murdering people to get them out of the way. In fact, Phil's cousin Ronnie has already killed once herself this year.
And Phil even arranged for a gang of thugs to beat his fiancee Sharon, leaving her fighting for her life.
These scenes are set to air next Thursday on BBC One.
