EastEnders' Patrick Trueman will confront his "lying" wife Sheree next week, a month on from her secret son being revealed.
The character married Sheree last year before the pair briefly split, over claims she'd had an affair.
But Sheree hadn't been with another man, with Isaac turning out to be her son.
The fact that she preferred Patrick to think she'd cheated than him meet her son left fans suspicious.
Fans quickly guessed he might have a criminal past or the pair are hiding something huge.
Some viewers even wondered if Patrick could be related to Isaac given his past with Sheree.
But next week it's Patrick asking all the questions, when he gets suspicious.
Denise, who kicked Sheree out thinking she'd rumbled an affair, arrives back to Walford and decides to clear the air.
After meeting Isaac, she apologises to her and they make amends.
But after Sheree continues to lie to him, Patrick confronts her.
He's been bonding with Isaac, but Sheree is forced to open up to her husband about her son next week.
Later on in the week, Isaac secures as new job at Walford High meaning he'll be sticking around.
Sheree, Patrick and Denise help him celebrate the good news, but it isn't long until further suspicions arise.
Isaac tells Denise that none of his mother's past partners ever seem to stick around once they meet him.
Denise's interest is piqued, but what will she find out and will it cause more trouble than good?
EastEnders airs Mondays and Fridays at 8pm, and Tuesdays and Thursdays at 7:30pm on BBC One.
