By 1923, Johns had left his wife. His RAF commission had been extended a further four years and he had moved to Birmingham, again working as a recruitment officer. In Birmingham he met Doris 'Dol' May Leigh (1900–1969), daughter of Alfred Broughton Leigh. They later moved to Newcastle upon Tyne when Johns was posted there. Although he never divorced Maude Hunt, Doris Leigh was known as 'Mrs Johns' until her death. Johns continued to pay for his wife and son's upkeep and for her nursing care (she suffered from acute arthritis).
