The biggest question of the fifth season of Arrow has been "Who is Prometheus?" Much like past seasons of their sister show, The Flash, Arrow has chosen to keep the identity of their big bad a secret.
With anticipation about the villain's identity only growing, many will wonder which member of Team Arrow is first to uncover the secret. And with John Diggle/Spartan recently freed from prison, he seems like a likely candidate.
David Ramsey, who plays Diggle, says that although his character has an extensive military background, he too will have issues with discovering Prometheus' identity.
"Well, it's not [easy for Diggle]." Ramsey pointed out, hinting that his time in jail, as well as the weight of his past decisions, might be the cause of that.
"Not to say his mind's not in the game, but I think his mind is making it in and out of the game. If had to point to a reason as why he didn't put it together, I would say that's probably the reason. I think Diggle is dealing with a lot of things this season. The new team, the regret, in and out of prison, his wife, his child, Flashpoint, alien abduction. So there's been a few things that have taken him out of the game."
Ramsey did hint that fans will be able to see an altercation between Diggle and Prometheus in upcoming episodes.
"There's a moment between Prometheus and John that we haven't seen yet. And we talked about it, me and the writers. And it ends up being physical to some degree. Keeping the fact that Diggle, even though obviously, we have to keep that big fight between [Oliver Queen] and Prometheus, that [Diggle] is still a character. So we didn't want him completely thrashed by Prometheus, but for him to sort of remain a real threat. We talked about things like that, and it's a great scene, it ended up being very very good as we kinda ironed that out."
And according to Ramsey, Diggle's involvement in that fight scene is similar to how Diggle ultimately handles the mystery of Prometheus' identity. "You can also make that same sort of comparison, in terms of finding out who Prometheus is and putting all of the pieces together."
Arrow airs Wednesday nights at 8 p.m. ET/PT on The CW. A new episode, titled "Bratva," debuts tonight.
