Inside Soap magazine reveal that David will find out that Gavin's not Gavin, he's Andy after all. David will notice Gail start to act weird (well, more weird than usual) and when Sophie mentions to David that Gail keeps popping into the shop to buy flowers, David gets suspicious.
He follows his mum the next time she pops into Dev's shop for a bouquet and strolls off behind her, wondering where she goes. Gail heads to the cemetery and lays the flowers on the real Gavin's grave.
Staggered by the discovery, David will challenge Gail and she is mortified when she realises the secret is out in the open.
What will David do with the information, I wonder? And how much longer can Gail keep the truth from Michael?
