Back in Castle Queen, Oliver tells some dude that a mysterious guy in a hood came in and saved him. The dude is a police detective and is very skeptical of the whole story. There's a sketch of the alleged hood-wearing vigilante. Tommy is unable to corroborate Oliver's story, saying he just saw blurry movement. Officer Dude continues to be skeptical. The kidnappers appear to have been pros with scrubbed identities and untraceable weapons. Officer Dude has vaguely insulting suggestions about ransom and parents, so Walter hustles him out. On his way out, Officer Dude sneers at Oliver, "Your luck never seems to run out, does it?"
Oliver looks up Adam Hunt online, so he can learn that Adam Hunt is a "Starling City Businessman" who has been "targeted by D.A. probe." His name is on a list in the book he got from the box. It is presumably an important list, so here are the names on it: Danny Brick, John Deloin, Hannibal Bates, Albert Davis, Adam Hunt, David Drayson, Isabel... something. I don't guarantee the spelling of all those last names, since the writing is very faded. And there are more names we don't get to see. Raisa (the maid) comes in and says Oliver's different. She says he missed her because the island didn't have a kitchen. He says he didn't have a friend. He didn't meet a friendly monkey? I was picturing a sort of wise gorilla who could teach archery. He wants to be the person she always told him he could be.
Downstairs, his mother introduces Oliver to John Diggle, his new minder. Apparently she thinks he needs a bodyguard just because he got kidnapped the first day he returned to civilization. John says to call him "Diggle" or "Dig" and does the driving with Oliver in the back seat. He says confidently, "My ability to keep you from harm will outweigh your comfort." So Oliver jumps out of a moving car.
It's the bad part of town, which I know because there are fires in barrels. Oliver brings a bag to that Queen Industrial building and parkours over a fence labeled "Danger. Keep Out." The warehouse is not in good repair. They didn't sweep up before they abandoned it. Oliver voiceovers that the abduction was unexpected so he had to move up his plans.
He busts up the floor and moves around machinery and knocks down a wall and generally sets up his secret lair. He turns on the power and sets up a lot of computers and monitors and green fluorescent lights so it has the right look. He sharpens his arrowheads and acts like he's training for Ninja Warrior. You know that move where there's a bar and they have to move it up through a series of notches by doing a sort of pull-up move? He's into that. Also, he dangles from his ankles and does core exercises. His big wooden box has a bow in it, duh. Up close, there are some pieces of filigree on it that kind of give it the same look as a rifle's stock. I approve of that.
