The revelation was hinted at during a Q&A held by The CW, with a photo of Mehcad Brooks as “The Guardian” expected to be released tomorrow.
UPDATE: Executive producer Andrew Kreisberg revealed that Olsen will take to the streets as a vigilante this year. “James has a pretty big turn coming up,” Kreisberg says. “These next few episodes are going to make him realize that being a photographer… is not enough for him, so he’s going to go on a pretty exciting career trajectory that we’re really pumped by. James is going to decide that he can no longer sit back and be a sidekick, so he’s going to decide to become a vigilante and he’s going to become Guardian – complete with the shield – which is going to cause a massive problem in his relationship with Kara [Melissa Benoist], because he has decided not to tell her.
“Now there’s this new masked vigilante, and she has her own feelings about vigilantes, and it becomes a push and pull about who gets to decide who gets to be a hero?” Kreisberg continues. “He’s recruited Winn [Jeremy Jordan] to help him, Winn is his man in the van, so the two of them are doing this together. Winn and James together is comedy gold. Watching Winn, as he takes his job at the DEO, but then he’s lying to everybody about how he’s spending his nights, because he’s going out with James, and how he walks in exhausted or walks in with a black eye and says he walked into a door, is the fun excitement of building these first 10 episodes.”
