Arrow Season 7: 7 Theories For Who The New Green Arrow Is
3. Barry Allen/Grant Gustin's Oliver Queen
This one wouldn’t have entered anything even approaching the equation were it not for the reveal of the Elseworlds poster, which sees Stephen Amell and Grant Gustin switching roles.
Since that means the crossover will feature, at least in part, Amell as The Flash and Gustin as the Green Arrow, could there be some slow build-up at play here?
It’d be difficult to have Gustin on Arrow too much, but that’d further explain why the identity of the archer is being kept such a secret: they can have someone else acting in the scenes, and then use Gustin for the big reveal in the crossover.
Further muddying the waters is that Amell’s Instagram post stated he is Barry Allen, which would actually mean that the Green Arrow in this case IS still Oliver Queen, just one who looks like Gustin. It’d be a risky, ambitious long-con to try and play, but one that might make sense when Elseworlds rolls around.
