In August 2015, John was approached once again by the ISA to rejoin the agency's ranks. His consideration of the job offer causes friction between him and Marlena, and recent conversations between the two revealed that although the pair remain very much in love, they were still separated and living apart at the time. John later revealed that the motivation for rejoining the ISA was to take advantage of its resources to find his parents and decode the mystery of his past, once and for all, for the sake of his children and grandchildren.
