Modern day Oliver is having a seizure! And then his heart stops! Felicity wants to call 911, but Diggle has some crash paddles. They don't work at first, which is either an electrical problem or because he didn't say "Clear." Felicity fixes the machine and then Diggle says "Clear" every time he uses the paddles. Oliver is fixed. Felicity explains that "wires are wires" so it wasn't that hard to fix.
Back to the tower in the flashback! The guard reaches for a phone and then Slade kills him. He complains about Oliver being useless, which he is. It turns out one man can kill eleven nameless, faceless guards. He tells Oliver to stay in the tower with the door locked. Oliver gets to keep the pistol, but he's warned not to shoot himself by mistake. He's clearly been demoted to "useless sidekick." Slade's off to go kill more guys and Oliver picks up the phone. He pushes a bunch of buttons and Laurel answers. Gasp! Oliver stands there without talking for awhile and Slade comes back in to bust the phone up. It might be bugged! Then the radio reports that the plane will be there in three hours. Slade acknowledges, and the pilot says, "Of all creatures that breathe and move upon the Earth." Slade asks them to repeat, like he's going to guess the answer. Oliver is delighted that they picked the one book he read in college. It's from The Odyssey and the rest of the quote is "nothing is born that is weaker than man." No, wait! It's "bred," not "born." Slade is skeptical, but he says it into the radio. It's a good thing Oliver read the exact translation they were using. Oh, and Slade is planning on "radioing in an air strike" on Fyers's camp as soon as he gets home.
Oliver tells Slade he can't blow up the island because it contains Yao Fei. Rescuing him was his mission! Slade doesn't care. Oliver says that Yao Fei saved his life, but Slade figures that's not his problem. Oliver is using his boring gruff voice now, which indicates that the island has transformed him. He says that he used to take people for granted, but he's not that person anymore. He won't leave Yao Fei here to die. Slade says he has three hours to go get Yao Fei and bring him back. Oliver asks Slade to call his family if he gets back without Oliver.
