The Flash Season 3: 7 Theories On Savitar's True Identity
7. Jay Garrick
What? John Wesley Shipp's wise old speedster could be Savitar? Say it ain't so! Well, no, it probably isn't, but he is a possible contender.
The biggest piece of evidence that suggests Jay could be Savitar is that he is currently stuck in the Speed Force - just as Savitar used to be. Obviously, Jay is only in there because he voluntarily took Wally's place, but who knows what the horrors of the Speed Force could have done to his mind during his imprisonment? Perhaps he goes mad and starts to resent Barry for his role in putting him there?
There is also the fact that Savitar is known as "the first speedster" to consider. In the comics, Jay Garrick is the first Flash. Though he is from an alternate universe - Earth-3, to be exact - in the TV show, the character's age could mean that he gained his speed before Barry. Which would still make him the first speedster.
On the other hand, the reveal that Jay Garrick is actually the season's big bad has already been pulled - as Hunter Zolomon pretended to be Jay in season two. And frankly, comic book fans would probably go crazy if The Flash turned the real Jay evil as well.
