Arrow type TV Show network The CW genre Superhero

As Oliver Queen—ahem, Al Sah-him (Stephen Amell)—inches closer to becoming the next Ra’s al Ghul, Team Arrow will make one last ditch effort to save his soul before the season finale, which is aptly titled “My Name Is Oliver Queen.”

“We’ve always said the season is about identity, and Oliver trying to decide between being the Arrow and being Oliver Queen,” executive producer Marc Guggenheim tells EW. “That’s obviously very present, as the title suggests, in the finale. Oliver’s arc over the course of the last episodes of the season relates to this question of ‘am I Oliver, or am I the Arrow.’ [It’s] very focused on that threesome” of Oliver, Diggle (David Ramsey) and Felicity (Emily Bett Rickards).

With Al Sah-him’s marriage to Nyssa (Katrina Law) on the horizon, and the subsequent potential destruction of Starling City to follow—wow, what a honeymoon!—Guggenheim teases that this year’s season-ender has the “same epic scope that we’ve established in season 1 and 2. It’s got some of the most emotional scenes that we’ve had in a season finale. We always say on Arrow that the season finale is time to go big or go home. I’m really optimistic [it] will feel every bit as big in terms of story and production value as our previous two season finales.”

But the team may find help from outside forces. “There’s going to be a big character returning for the finale that we haven’t announced yet,” Guggenheim says. EW can reveal that character is The Flash (Grant Gustin)—but even with the scarlet speedster on the case, Guggenheim cautions that fans should be very worried about their favorite heroes.

“We’re at the point in the season where, I think our fans know, it’s usually when the culling happens, so I think everyone knows that they’ve got reason to be afraid,” he says, noting that there won’t be a traditional cliffhanger leaving fans wondering about their favorite characters’ fates. “The season 3 finale of Arrow is very definitive. It really feels like the end, not just of season 3, but of the first three seasons.”

Though Guggenheim is cagey on what will happen in the finale, he does reveal what won’t happen. “The Arrow finale doesn’t relate to the spinoff at all,” the EP says of the planned project featuring Brandon Routh, Caity Lotz and many other familiar faces. “It’s pure Arrow.”

Arrow airs Wednesdays at 8 p.m. ET on The CW.
