Charity knows!

She spots Mack cradling Chloe's newborn son and twigs he's the dad...

- 

The moment that Mack has been desperately trying to avoid happens this week as his newly-wed wife Charity realises that Chloe's newborn son is her husband's child! If only Mack had confessed to his one-night stand with Chloe when it happened after he and Charity had their bitter row about having kids, it might have been different.

But Mack kept quiet and has been trying to conceal the sordid secret ever since.

When Charity took pity on pregnant Chloe and took her in, the stakes became even higher, and now she and Mack are married to boot.
