Over the past few months, Joseph has been complaining of headaches and generally feeling unwell.
This happens once more in upcoming episodes, as Joseph tells Chesney and Gemma (Dolly-Rose Campbell) that he has another headache.
Chesney is adamant his son is fine, but Gemma shares her worries with Paul (Peter Ash).
Pointing out that she could jeapordise her investigation with social services, Paul advises Gemma to keep quiet.

Later in the week, a newly returned Linda (Jacqueline Leanord) speaks to Chesney about a family solicitor and hands him a business card.
Back at home, when Joseph gags on his milk, Chesney realises that the fridge is broken and all the food has gone off. He emerges from Number 5 with an unwell Joseph and assures Gemma that he just has an upset tummy, but it leaves Doctor Gaddas curious.
