The Flash Season 2: 12 Big Questions After 'Escape From Earth-2'

4. Who Is The Man In The Iron Mask?

I was asking this question last week too, but now it's really pertinent. Just who is that man in the iron mask, caged up in Zoom's lair? There were a couple of clues this week, although thinking about them makes things all kinds of confusing. There's the fact that he's using a PoW code, which suggests he's been involved in war himself. And then there's that shot of the back of his head, clearly showing he has blonde hair. Couple those things with the fact that he spelt out Jay, and, well, it points to him being Jay Garrick. But, then, Garrick's on Earth-1, isn't he? And we've seen his doppelgänger there too, Hunter Zolomon. So how can it be him? Unless this is the REAL Jay Garrick, and the one on Earth-1 some sort of evil creation of Zoom's, like a mega speed mirage. Or they could be twin brothers, with a set of twins on each Earth. Or one of them might be from the future. Or maybe that's wide of the mark, and it's really Eddie Thawne?
