Eddie Thawne is back! Well, okay… maybe not. Actor Rick Cosnett has definitely returned to The Flash, but considering Eddie is dead, who knows who he’s playing?

Earlier this month, Cosnett announced he was returning to the show, and new photos from the set reveal that he’s currently filming.

Cosnett himself posted a photo on Twitter with actor Jesse L. Martin on The Flash set:

(I’m loving the Flash lapel pin, by the way.)

Actress Candice Patton also posted a photo to Twitter showing herself, Cosnett, Martin, and series star Grant Gustin:

Eddie Who?

Now, here’s where things get interesting. On a show like The Flash, there are a lot of possibilities for whom Cosnett is playing. It could be Eddie’s doppelgänger from Earth-2, Earth-3, or any number of infinite Earths (see what I did there?). It could also be the Flashpoint version of Eddie, brought to the current timeline by Julian or Savitar.

The simplest explanation, though, is that Cosnett is simply appearing in a flashback. Lending further credence to that theory is Gustin’s Flash costume in the photo above. You’ll notice the Flash logo has been removed from his chest. While it could’ve simply been taken off for some reason, it stands to reason that he was actually wearing the original Season 1 logo while filming, and it was removed to avoid spoilers in the photo.

Who knows? We’ll likely found out more when the episode gets closer to air.

The Flash airs Tuesday nights at 8/7c on The CW.
