I realize that some people will think this theory is a bit of stretch, especially since there are so many other possible candidates as well. Plus, who wouldn't love to see this guy back on our screen again? So having Earth-2 Eddie show up and save the day is well within this show's wheelhouse. What's to say he won't turn out to be just as important this season as well? The Flash does an amazing job of surprising us time and time again. He was the key to stopping the Reverse Flash and saving Barry from death (by killing himself). It's also worth mentioning how important Eddie turned out to be at the end of last season. Now, given that this person's entire head is covered, it's hard to ascertain many clues regarding his (or her) appearance, however, it isn't too big of a stretch to say that the Iron Mask character seems to have a similar body structure to Eddie. Why is that, do you think? The way I see is either a.) the actor who plays Eddie, Rick Cosnett, is way too busy with his new role on Quantico to stop by The Flash set, or b.) the writers are saving his return for a much bigger revelation later on. we saw pretty much everyone's doppelgänger (evil or otherwise) during Barry's trip to Earth-2. (If only!) But then I started really thinking about it and came to the conclusion that the man in the iron mask is actually Eddie Thawne from Earth-2. Who is this guy? Why is he Zoom's prisoner? And how does he fit into the rest of the story? At first, my initial reaction was to say that it's obviously Leonardo DiCaprio reprising his Man in the Iron Mask persona.

And even though we've now unmasked Zoom, there's still yet another mystery left to uncover: the identity of the man in the iron mask on The Flash.

That's some next-level plot development right there, my friends. I mean, here we are in the show's sophomore season and not only have we traveled back in time on more than one occasion, but we've also journeyed to an alternate universe (aka Earth-2).

One of the many things I love about The Flash is how ambitious it's always been.
