David
 Platt isn't pleased to see Gemma and doesn't show
 any sympathy when she pleads for a chance to turn her life around.
Just as Gemma is about to give up and go, she bumps into David's sister 
Sarah and is shocked to see that she's visibly pregnant.
Gemma guesses that Callum must be the
 baby's father, so she resorts to her old tricks by threatening to tell 
him everything unless she can keep her job.
David isn't too worried about this possibility either and calls Gemma's bluff, but he's hit with an idea when she claims that she only spoke to Callum a few days ago.
Realising
 it could help their murder cover-up if Gemma is mouthing off about 
Callum still being alive, David sneakily persuades Audrey to keep her at
 the salon after all.
Gemma is delighted to be given a trial, but will David live to regret his latest cunning plan?
