Emmerdale's Charity Dingle learns her husband Mack's baby secret in Thursday's episode (ITV, 7.30pm see our TV Guide for full listings).
So Mack's being totally weird and his wife Charity doesn't know what's got into him. But she's about to find out…
With baby Reuben, who's contracted meningitis, still very unwell in hospital, Mack is going out of his mind with worry.
Not that he can share his stress with his wife, of course, as she doesn't know he had a much-regretted one-night stand with Chloe Harris, who gave birth to his son on Mack and Charity's wedding day.
As stressed-out Mack ghosts his wife and talks things through with his in-the-know best mate Nate, he comes to the conclusion he's just got to go to the hospital even though he and Chloe have vowed to steer clear of each other.
Mack and Chloe are together when the consultant shares fantastic news. Reuben is showing no signs of brain damage and will be OK.
As the great news filters back to the village, Charity and Chloe's sister Amy decide to pay a surprise visit to the hospital.
Uh oh.
Unaware that his wife is on the way, Mack's thrilled when Chloe asks if he wants to hold his son.
As Charity clocks the tender scene through the window, in an instant she realises that the man she has just married is the father of Chloe's child.
How will Charity handle the brutal bombshell?
