The pressure continues to grow on the Platt's as Callum's mother Marion calls at Number 8 wanting answers about her son's whereabouts. David's having none of it though and throws her out calling Callum a drug dealing thug, while later he realises that Sarah has been chatting to Billy and freaks out. Dragging Sarah into the Rovers back yard, David berates her for blabbing to Billy and tells her that if she does it again, he and Kylie will tell the police that she killed Callum and forced them to cover for her. Jaysus, she's your sister! This whole thing is really bringing out the worst in David, although he was never really whiter than snow anyways.
