Legal aid office. We can go ahead and assume that the Single Female Lawyer from before is Laurel Lance. She and a friend discuss justice. That's what lawyers do, you know. They either stand around and talk about justice or they're evil corporate monsters. One or the other. Their conversation is cut short when Laurel learns that Oliver is there, poking at her clippings-and-string board.
They go out walking so Oliver can exposit that Laurel hadn't gone to law school yet when he vanished. They have some small talk about Adam Hunt before moving on to the main event: "Why are you here, Ollie?" He's here to apologize and ask Laurel not to blame Sarah. She asks "For what? Falling under your spell? How could I blame her for doing the same thing I did?" See, Oliver was Laurel's boyfriend. He tells her, "I know that it's too late to say this, but I'm sorry." She hoped that he'd rot in hell a whole lot longer than five years. She passes Tommy on the way out.
Tommy and Oliver are going back to the car, when Suddenly! A van shows up and Tommy and Oliver both get tranquilized by guys in red skull-masks! A witness gets machine-gunned to death so we know they mean business. As Oliver falls, he flashes back to the lifeboat. His father tells him he didn't build the city: "I failed it. And I wasn't the only one!"
A hood comes off Oliver's head. He's sitting on a wooden chair and his hands are zip-tied behind him. And a guy with a red skull-mask is in his face asking questions. I'll call him "Skully!" Skully asks if Oliver's father survived the accident. What, Skully doesn't watch the news? Oliver doesn't answer, so Skully gives him the old stun-gun. Skully asks if Robert (that's Oliver's father's name) made it to the island. Did Robert tell Oliver anything? Oliver grimaces and says that he did. "What did he tell you, Mr. Queen?" "He told me I'm gonna kill you." What? That's a weird thing to tell him.
But there's no time to parse that sentence, because Olive is miraculously un-zip-tied! He lifts the chair and lays waste to the goons. One guy has a machine gun, but when he shoots at Oliver, he's holding a goon as a human shield. Tommy has been lying face-down on the floor this whole time, so Oliver checks his pulse (possibly resurrecting him with miraculous island powers) and parkours after the last guy.
Throughout the chase, Oliver is busting out fancy parkour moves, because it turns out that a jungle island is the perfect training ground for urban parkour. And the Skully with the gun occasionally stops and fires a burst of bullets at Oliver, but he misses every time. Eventually, he loses his skull-mask. Oliver swings on a chain in a very showy move to catch up with him. "Nobody can know my secret," he says, before breaking the guy's neck. Wow, not even some interrogation? Oliver would rather kill the guy right away than find out who sent him, I guess. That seems like poor strategy.
