A reminder, in case you haven't been paying attention during the previous four seasons of Arrow: "There's no secret that doesn't eventually get discovered," says executive producer Marc Guggenheim.
He's specifically referring to the fact that when Barry Allen changed the timeline on The Flash, Diggle (David Ramsey) and Lyla's (Audrey Marie Anderson) daughter, Sara, turned into their son, John Jr. But that rule can apply to pretty much anything on this show.
Take, for example, the fact that Felicity (Emily Bett Rickards) redirected a nuclear bomb toward new Team Arrow recruit Rory's (Joe Dinicol) home. Felicity came clean at the end of "A Matter of Trust," but it's probably for the best that she did since it would've come out eventually.
Another secret Felicity's keeping that could be revealed at any moment? That she has a new boyfriend. "It's the classic thing of no secrets stay secret on Arrow forever," Guggenheim says. "Oliver is going to find out about Felicity's boyfriend in 505," he teases, "and because I'm spoiling that I'm not going to spoil when Felicity's boyfriend finds out that Felicity is working with Arrow."
Right now, Team Arrow is currently contending with the reaction to Lyla's proposal to break Diggle out of prison. "It's funny, I actually think Oliver and Felicity both have interesting reactions and they're not necessarily on the same page, let's put it that way," Guggenheim says. "They don't see eye to eye on Lyla's plan."
Plus, the new recruits are adapting to their roles. While we saw Curtis (Echo Kellum) suit up tonight, that doesn't mean he's made his official transition to Mr. Terrific. "I think he's still got a ways to go on his journey. For one thing, that's not his final costume. We've decided to sort of give some of the recruits what we call proto-costumes—you've gotta earn the final one," Guggenheim says.
And Curtis hasn't earned his quite yet. "In terms of all these characters being vigilantes, Curtis has the farthest to go. The evolution of Curtis from comic relief and sidekick to butt-kicking superhero, that's a big throw in my opinion. So the only way to do it properly is to watch him try and watch him try and watch him fail, and then watch him fail, and then watch him fail. So it's going to be a real struggle for him as we go through the fifth season."
Arrow airs Wednesdays at 8 p.m. on The CW.
