Logistically, this is doable for the series; although very little is actually known about Earth-1’s Hunter Zolomon, the series clearly showed him as a park-visiting resident of Central City during the events of Season 2.
Although he likely won’t return as Earth-2’s Zoom (because Zoom is now Black Flash, even if they don’t call him that), Sears explained to the audience that he wants to take on the role of Hunter Zolomon from Earth-1.
If Teddy Sears wants to come back, there’s a clear path to make this happen, but while it’s an exciting prospect, it also seems to serve as confirmation that Zolomon is not the man lurking beneath Savitar’s mask.
Teddy Sears recently took the stage and admitted to the crowd at Planet Comiccon in Kansas City (via Comicbook.com) that he is very interested in returning to the world of The Flash, following his recent stint on 24: Legacy, but that it hasn’t happened yet.
