SPOILER WARNING: This article contains major spoilers for “The Reverse-Flash Returns,” the most recent episode of “The Flash.”
In the last episode of “The Flash,” Caitlin Snow discovered Jay Garrick is dying as a result of the loss of his speed. In an attempt to save him, she kicked off a search for his Earth-1 doppelganger in the hopes they could use the double’s healthy cells to heal him. Now, in “The Reverse-Returns,” Jay revealed the reason she had such trouble tracking his doppelganger down: Earth-1’s Jay Garrick was adopted. And his name?
In the comics, Hunter Zolomon becomes Zoom, who fans may recognize as this season’s big bad. The character first appeared in Geoff Johns and Scott Kolins’ “The Flash: Secret Files & Origins” #3 as Zolomon, before taking up the mantle of Zoom in “The Flash” #197. Over time, he became good friends with Wally West, before the two had a falling out after an accident resulted in his paralyzation. He attempted to use the cosmic treadmill when Wally refused to go back and save him, and the resulting explosion dislodged him from the timeline, thereby giving him super speed.
The show revealed Caitlin’s plan to use Zolomon’s healthy cells simply wouldn’t work, as Jay’s cells had mutated thanks to his brush with the Speed Force, and explained how his Earth-1 mother passed away in childbirth, resulting in his adoption by the Zolomon family. While he may not have super speed yet, that doesn’t mean Zolomon won’t become a villain for Barry — or maybe even Wally — at some point in future seasons of “The Flash.”
Zolomon wasn’t the only surprise of the episode. Cisco and Harrison Wells also collaborated to create Vibe glasses, which enable Cisco to tap and target his abilities.
