What's next for Isaac?
As Sheree tries to get Isaac to take his medication, he's stopped by his auditory hallucinations.
Later, Lola, Kim and Patrick discuss Isaac’s condition but Patrick tells them to leave it to Sheree, unbeknownst to him that she is also struggling.
Isaac stops Lily and Arthur as they arrive home with Ruby, persuading them to go on a picnic and stay away from the house, to keep them out of harm’s way.
Ruby then catches Isaac trying to break into her house. Noticing the commotion, Martin and Sheree rush over to a panicked Ruby who doesn't know where the kids are.
As the situation intensifies, Isaac gets more distressed and when Martin goes to call the police, Isaac makes a run for it into his house.
As Ruby and Martin wait for the police, they're beside themselves and Patrick tries to calm Isaac down and eventually gets let in.
Asking him where the children are, Patrick promises that he won’t let anything bad happen to him. After Patrick manages to coax Isaac outside for a moment, he's spooked and runs back inside.
Meanwhile, Jean receives a call from Lily and finds her and Arthur in the allotments.
