"Arrow" executive producer Marc Guggenheim offered more insight on how Sara Lance will return to the living, Coast City, Oliver's legacy, Thea's secret identity and more during an interview with Entertainment Weekly.
"[Sara's resurrection] very much comes about because of decisions that Laurel makes and choices that Laurel will then have to live with," Guggenheim revealed. "The episodes dealing with Sara's return are amongst probably the heaviest material that we've had for Laurel. We're using Sara's return to really get underneath not just Laurel as a person, but the relationship that she has with Thea and the friendship that she has with Oliver."
Guggenheim also teased more Green Lantern mythology, though he refused to make any confirmations: "There is a nod or two... There is a billboard that people will get a kick out of, and there may or may not be a ring in the season premiere." He did not, however, specify what color ring we may see in the upcoming season, if there is one at all.
He weighed in on how Team Arrow will manage to convince Oliver Queen to return as the Arrow, saying, "We're gonna learn that this villain [Damien Darhk] has been operating in town for the past three months... Team Arrow has basically been trying to keep [him] at bay, but then something happens in the season premiere that's the straw that breaks the camel's back and it prompts Laurel and Thea to go find Oliver and get him to return."
However, when he picks the bow back up, Oliver won't be the grim vigilante we've seen in previous seasons. "We played him as a guy who was returning home from war with PTSD for the first three years," Guggenheim explained. "Now he's put those demons to rest, or so he thinks, and there's a lightness to him as a result of all the things he learned last year... It's less about erasing his father's legacy and more about establishing his."
Additionally, the vigilante lifestyle will carry a different burden for Thea. "Since season 1, we really haven't done that much with Oliver trying to keep his secret identity secret on the show," Guggenheim shared. "But that's something we're going to be playing around with Thea as we get deeper into the season and she tries to balance hopefully a personal life with being a superhero -- something she's never had to deal with before."
