Peter Beale (Ben Hardy) will be seen using drugs next month following a falling out with dad Ian (Adam Woodyatt) and girlfriend Lauren (Jacqueline Jossa).
Despite the best efforts of Jane (Laurie Brett) to mend relations, Peter will end up meeting with a drug dealer and buying cocaine.
The shock storyline comes just as the Beales plan to mark Peter’s 21st birthday with a party at the Albert. Unable to deal with having a celebration without his late sister Lucy being around, Peter slips away and takes the drug, only to be caught by Masood (Nitin Ganatra).
Peter then heads home and bangs on the window, calling out for Ian who sits inside ignoring him. Jane finds Peter and tries to stop him, but in a moment of temper, Peter bangs on the window so hard that it smashes. Will father and son work through their differences as a result of the accident? Or do the fissures within the Beale family run too deep?
