Moira strolls into Q Consolidated because Walter is late for lunch with her. He's distracted because someone has mysteriously withdrawn 2.6 million dollars from their Vancouver branch. That's pretty much the whole scene.
Police station. Laurel and her father (either Detective Lance or Officer Dad, depending on how I feel) go over the evidence against Declan. There's a hole in his story; where he says his wife talked to her supervisor (Matt Istook) about Brodeur dumping chemicals, the supervisor denies that the meeting ever happened. As Laurel starts to leave, her father asks why she's defending criminals now. She suggests that maybe Declan isn't a criminal. I guess it's possible, but there hasn't really been any evidence of that yet.
It's Dig! He's in that diner talking to his sister-in-law Carly. And then Oliver and Rob stroll in. Rob officiously reports that the area's secure. He's probably guessing about that, since he and Oliver just got here. Oliver tries to charm Carly, but is unsuccessful. Oliver sits in a booth with Dig and asks if Dig has considered his offer. Dig is contemptuous of Oliver's new vigilante persona. Oliver shows him the Notebook (the one he found while burying his father, not the Ryan Gosling movie). He wants to right the wrongs done by his family and offers Dig a change to right the wrongs done to his. Dig's brother Andy was killed by bullets laced by curare and there's only one weirdo dumb enough to do that: Floyd "Deadshot" Lawton, who Oliver killed last week. He talks tough about how he's going to right all the wrongs. Then he stands up. As Rob scurries over, Oliver claims he's going to the bathroom. Rob stands awkwardly next to Dig for awhile until Dig tells him that Oliver has obviously run off again.
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.
