The Russian goon says The Count got that name because when he was developing the drug, he'd experiment on homeless people. And their bodies would be found with holes in their necks! Then The Count shows up. He says he's not concerned about the police. Oliver's story is that he's opening a nightclub and wants something nice for the clientele. Diggle hands over some duffel bags of cash. The Count has some pills and claims that 56 people died to make them.

And then! The police are here! Gunfire! Oliver should probably get out of there. He runs after The Count, who gets him in the chest with a couple of needles. "No witnesses!" he says, before fleeing down a staircase. Oliver's friend shoots up the Russians' car and makes it stop. Diggle finds Oliver and helps him up.

Back to the Arrowlair! Diggle sets a shirtless Oliver on a table and mixes up some herbs. Oliver grabs him by the neck for no apparent reason, but Diggle gets the mixture into his mouth. Oliver screams!

Back on the island, Oliver is fighting Yao Fei in the circle. Yao Fei gets him in a sleeper hold, then lets him fall.

Oliver wakes up handcuffed to the table. He promises not to kill Diggle, who obligingly uncuffs him and gives him a shirt. Apparently he only got a half-dose. But they came away with some Vertigo. Oliver refuses to rest up from the massive drug overdose he just recovered from.

Castle Queen. Detective Lance and Officer McKenna are here to talk to Oliver. I realize "McKenna" is her first name, but "Officer McKenna" sounds cooler than "Officer Hall." There was a drug deal last night, and an eyewitness saw Oliver there. And that eyewitness was McKenna, which is awkward for Oliver. Oliver admits that he was checking into The Count, hoping to get a look at him. Moira is a little stressed out by this. So is Detective Lance! But he's willing to accept this story. Before the cops leave, Oliver thanks Lance for helping Thea. When they're alone, Moira shouts at Oliver about sneaking around with drug dealers. Oliver thinks she's really angry about him telling Thea about their father, and then Thea comes back in. Now she's all sad and repentant. They have a tearful hug. Oliver walks out of the room.
