EastEnders spoilers have hinted Ben Mitchell will uncover his stepmother Sharon's secret affair with Keanu Taylor.
After a fling in 2018, Sharon and Keanu slept together again earlier this year and Sharon fell pregnant.
Keanu is dating Ben's sister Louise, who is now also expecting a baby with the mechanic.
Mel Owen, Louise's godmother, recently discovered that Keanu is the father of Sharon's unborn baby, and she's been blackmailing her amid her revenge plan against the Mitchells.
Next week, she leaves Ben suspicious with it teased he might now work out what has been going on.
It all kicks off when Mel is pushing for her, Keanu, Louise and Louise's mother Lisa Fowler to move to Portugal - despite neither of them being that keen to go.
Lisa knows Mel has something on Sharon, but doesn't know the truth about the baby and Keanu.
After Mel tried to get Sharon to sell the nightclub to Ruby Allen, Ben wanted answers.
In scenes airing this week, Sharon admits to him that Mel is behind her decision to sell up.
Fast-forward to next week, and Ben grows suspicious over Mel's behaviour and confronts her - but he's not expecting the outcome.
Ben urges the club owner to stop hassling pregnant Sharon and to leave her alone.
He's left intrigued though when Mel confesses she knows a Mitchell family secret.
Ben asks Sharon about what she said, but she quickly plays things down while panicked about being exposed.
But knowing Ben, should she and Keanu watch out and will Phil's son go snooping until he discovers the truth?
EastEnders airs Mondays and Fridays at 8pm, and Tuesdays and Thursdays at 7:30pm on BBC One.
