“What’s funny is we showed that Jay’s doppelganger was Hunter Zolomon, and we assumed the comic book fans would say, ‘A-ha’ right away…But I think that, like Barry and the team, they didn’t want to or just couldn’t believe it.”
Kriesberg went on to say:
“The mystery of the Man in the Iron Mask will play out over the rest of the season with some clues being layered in along the way,When you do find out who it is, everything will make sense in a very satisfying way.”
Zoom turning out to be Hunter Zolomon is a twist that lots of fans spoke about earlier in the season, but Jay showing his Earth-1 doppelgänger (or whom he claimed was his doppelgänger) seemed to throw people off of that.
