When it comes to questions fans have about The CW's Arrow as the series heads towards its eighth and final season this fall, some of the bigger ones involve Diggle's family -- specifically what's going on with his children in the future timeline. In Season 7, fans became acquainted with Connor Hawke (Joseph David-Jones), Diggle's adoptive son but were left wondering about his real son -- John "JJ" Diggle Jr. Now, it seems like fans might actually get answers as the series is reportedly now casting for the role.
