John panics when he finds Holly agitated in her room. Deeply uneasy, Adam tells John that he thinks he knows why she's so fraught and so desperate for her mum. At the police station, ashamed Moira is unable to face her family and calls Diane. She tells the truth, but the officers emphasise the seriousness of her crime - possession with intent to supply. Back at the house, Adam tells John it's not a lapse, its fresh withdrawal - he thinks Moira's gone to score for Holly.
