Despite its Oliver Queen (Stephen Amell) focused title, "Arrow" really is about a whole lot more than just, well, its Arrow. Queen's story of tragedy, redemption and vigilante justice has involved a whole circus of revolving superheroes, which is why fans weren't entirely shocked when David Ramsey answered ComicBook.com's [multiple] "John Diggle as Green Lantern" questions with a solid "anything can happen."

Well, according to "Arrow" showrunner Marc Guggenheim, anything can happen, but as for Ramsey's character changing from John Diggle to John Stewart, don't count on that just yet... mostly because Diggle has become so important to the "Arrow" universe -- and the DC Comics universe, which he was written into thanks to Ramsey's phenomenal work on the show -- that changing him into someone else would be a major disservice to everyone involved.

"It’s funny, I’ve spoken to David quite a bit about this issue, I know it keeps coming up," Guggenheim told MTV News over the phone. "I spoke to [writer] Geoff Johns at DC after that interview went viral. Basically, John Diggle is now a character in the comics... John Diggle is John Diggle. We’re not being coy and saying John Diggle is someone else, i.e. John Stewart. DC has other plans for that character. We love David, and we love the character of John Diggle that he’s created. We have really cool plans for him... they involve a wedding ring, but they don’t involve a power ring."

So there you have it... at least for now. But as for Ramsey's assertion that anything can happen regarding new superheroes and/or vigilantes, that remains 100 percent true. In fact, Guggenheim said that there are current members of the "Arrow" roster that might later become DC Comics heroes.

"There are two characters who would probably fall into that category," he said. "Were we to do it, they would be characters from the comics that you already know."

... Woah. Let that one sink in, and enjoy playing the who's-who guessing game. And in the meantime, while they figure out who to unmask (or is it mask?) next, enjoy this tidbit on what's next for Felicity (Emily Bett Rickards) after her emotional split from Oliver.

"She is every bit a part of Team Arrow as she’s always been, she’s just now doing it under the shadow of having this conflict with Oliver," Guggenheim said. "I think what Oliver is doing... I wouldn’t go so far as to say it drives her into Ray’s arms, but certainly Ray now has the opportunity to exist in contrast to Oliver. In episode 15, for example, the differences between how Oliver does things and how Ray does things are very different, and very stark, and very sharply drawn. That’s not lost on Felicity. She’s aware that Ray is a very different kind of person than Oliver, and we’ll see what she does with that epiphany."
