At Castle Queen, Moira walks in on Walter, who's still trying to locate that missing money. It turns out she invested 2.6 million dollars in "a friend's startup venture" three years ago. So everything's fine! Although Walter seems to think that's weird.
Legal aid place. Laurel tells Joanna that "guardian angel" wanted her to investigate. Joanna immediately knows that the guardian angel in question is the hooded vigilante, who goes against everything Laurel allegedly stands for.
A rooftop. Laurel says, "I got your message. Is there a reason we can't do this face-to-face." The camera pulls back and the person she's talking to is like ten feet away. Isn't that face-to-face? It's not like they're communicating via carrier pigeon. He's right there! Anyway, they decide that Declan's wife's supervisor needs to confess that she talked to him, because that will prove that there's a hole in the official story of Declan killing his wife. Oliver's going to go bully him into testifying the way he wants, although Laurel objects on ethical grounds. Oliver claims that he does "what's necessary" and is only wearing a hood to "protect the ones I care about." Then he shoots an arrow at a nearby building and WHOOSH! ziplines away. We don't see it very clearly, because it's probably more complicated than it sounds to set up a zipline like that. You probably have to aim the arrow at a very particular wall and then you'll want to set up the belay on your side pretty carefully. But here, it looks like he just shot an arrow and was immediately sliding away.
Felicity Smoak (from last week! She's recurring!) stomps into Walter's office late at night to demand why she's being fired. She isn't! He just wants her to look into the details of that 2.6 million dollar transaction. Discreetly, like without his wife finding out. It's weird that she assumed she was being fired because she was summoned to his office in the middle of the night. Some people might imagine an even more sinister motive for a boss to summon a pretty young worker to his office, you know?
A guy in a suit goes out to his flashy convertible when there's a noise. Oops! Dart in your neck! He falls.
Then he wakes up, handcuffed to a railroad track. Oliver's there and calls him Matt Istook. So wait -- Oliver's literally tying people to railroad tracks now? Not only is he not a hero, he's a melodrama villain! Istook calls him "That hood guy" and Oliver says that if Istook doesn't tell him the truth, the 10:10 to Blüdhaven will kill him. If you're curious, Blüdhaven is next to Gotham City. When Dick Grayson gets tired of being Robin, he moves there and operates as Nightwing. Anyway, Istook buckles immediately and offers to give Oliver "the file." Oliver shouts, "Where is it?" Hey, man. The guy's cooperating. You don't really need to shout at him. Oliver vanishes into the darkness so Istook has to panic and shout about where the file is. The answer is: in his desk. At the last second, Oliver shoots the chains with an arrow so Istook can live.
