A man dressed as an elf witnesses a house exploding. He needs treatment because his ears are stuck on and Charlie and Jane realise he is a thief. A fireman rescues the house's elderly occupant but she dies in hospital. The fireman later collapses from smoke inhalation; his wife, who hasn't left the house in over a year, manages to visit him in hospital. A girl who has suddenly gone blind is brought in; she quickly regains her sight but turns out to have a brain tumour. Josh and Lucy nearly run over the new hospital chaplain. Charlie is missing Duffy, causing him to be bad-tempered, but softens when Frankie saves him from choking with the Heimlich manoeuvre.
