"Arrow's" fifth season has already had it's fair share of mysteries. Some of them have already been addressed, like the identity of the villainous Prometheus, while others still remain wrapped in obscurity, like the man behind the Vigilante mask. However, there's one more mystery that's developed this season; one that fans - and more importantly, Felicity - will soon have some answers for: the identity of the leader of Helix.

So far, the face of the hactivist organization known as Helix has been Alena (Kacey Rohl), but executive producer Wendy Mericle told Entertainment Weekly that someone far more elusive is truly pulling the strings. "We are going to see somebody [else]," Mericle said. "What’s interesting about it is he’s not actually at Helix right now, so there’s going to be a big episode where we find out who this person is, and Felicity is involved in helping him. It’s really messed up."

In the comics, Helix was a group of six mutated children who were experimented on while they were still in the womb by Dr. Benjamin Love, AKA Mr. Bones. While the prospect of seeing Bones' transparent flesh-covered face come to Star City certainly sounds intriguing, it's more likely that The CW version of Helix's leader will be more grounded in reality to keep in line with the overall tone of the series.

In addition to Mericle's comments, executive producer Marc Guggenheim also chimed in, informing us that Felicity's dealings with Helix will ultimately help her better empathize with her teammates, particularly Oliver and Diggle. "Felicity’s use of Pandora is very similar to Oliver and Diggle’s [David Ramsey] use of violence," Guggenheim said. "It’s the hacker equivalent. You’re using violence for a good means, but violence is not necessarily a good thing. So what’s the cost to Felicity in doing that? We don’t want to turn Felicity into a killer, but we wanted to explore how Felicity has been spending basically five years with Team Arrow now, and she’s been spending five years with people who solve problems by not just resorting to violence, but by resorting to means that are morally questionable. Felicity is going to start discovering what happens when you fight fire with fire — do you get burned?"
