Jack Branning has become suspicious over Linda Carter's pregnancy in EastEnders.
Linda found out earlier this year that she got pregnant following her brief affair with Max Branning at the end of last year.
After finding out Max kidnapped baby Abi during a visit with brother Jack in Paris, the Carters chose to say Mick is the father of Linda's baby as a way to keep Max out of their lives.

Tuesday's episode saw Linda in serious danger when two thieves tried to rob the charity bucket at the Vic following Whitney Dean's musical performance.
What to Read Next
Mick had left Linda to lock up while he went off with Whitney, Rocky Cant, Karen Taylor and Mitch Baker to grab dinner following the show, but the robbers attacked once Linda was on her own.
Little did Linda know Zack Hudson was sneaking around with her daughter Nancy upstairs while the gig was going on. The two heard the commotion in the bar, leading Zack to intervene to save Linda.
Detective Jack Branning arrived to investigate the crime, telling the Carters that his team were on the trail of the robbers because they'd also tried to rob a corner shop nearby.
When Linda told one of the other officers she's 36 weeks pregnant, Jack whipped around — seemingly surprised because Linda still would have been with Max at that time.
Linda briefly made eye contact with Jack after realising the mistake she'd just made. Jack let out a nervous sigh, but didn't directly mention the admission to Linda or Mick.
Will Jack be able to keep this damning revelation from brother Max?
EastEnders airs on Mondays, Tuesday, Thursdays and Fridays on BBC One.
