The couple's relationship has been under strain since Whit arrived back in Walford with Britney Wainwright in tow. Whitney declared her intentions to foster Brit, but hasn't told Zack the full story of what went down in Milton Keynes.
Following the devastating discovery that Britney has Type 2 Usher Syndrome, Whitney is keen to know more about the condition.
Fearing what all this stress is doing to their unborn baby, Zack suggests they enroll Britney at the local GP, but Whitney panics her secret will be exposed and makes out she's already done it.
Later, Whitney tries to persuade Sonia Fowler to skip the checks required to register Britney as a patient.
But when that fails she's forced to haul Britney's mum Keeley to the Walford surgery to sign her daughter up.
Can she trust Keeley to keep schtum?

Zack is furious to find out Whitney has put Britney before their baby and a heated row breaks out between the pair.
Tensions continue to mount at Sonia's dinner party, before concerned Lauren Branning pulls Whitney aside and insists either she tells Zack the whole truth about Britney's fostering - or she will!
