The DC universe on The CW went through some big changes this fall thanks to the Flashpoint arc on The Flash that altered the timeline of all three Earth-1 series. The Arrow character most affected by the Flashpoint timeline is undoubtedly John Diggle, whose baby daughter Sara was replaced by a baby boy named John Jr. The big question now is of whether the new John Jr. in the Flashpoint timeline is the same John Jr. who took up the mantle of the Green Arrow in one possible future, as seen on Legends of Tomorrow Season 1. Arrow and Legends executive producer Marc Guggenheim said this about John Jr.: We go back and forth on that.
