Back to Flashback Island. Oliver is suited up with the Ninja Soldier's gear. You remember the Ninja Soldier, right? He fell on a rock and died. He even has the sense to pull on the ski mask when he goes up to a tent with other soldiers and gets in line for chow. Somebody is surprisingly friendly and offers him a ride over to the main camp. They set down their trays of gross food and get into a jeep. But before they can go, the general shows up and gets in. That's Edward Fyers, the guy who's in charge of all these ninja soldiers.
Upstairs from the Arrowlair, Tommy harasses workmen about getting the warehouse ready. His father Malcolm (John Barrowman!) calls and gloats about how his tough love made Tommy get a job. Tommy's still bitter about being cut off without a cent, but Malcolm wants to have dinner with him and Laurel. Tommy's willing to consider it.
Oliver shoots a couple of people with darts (hey! Non-lethal! Good for him!) on his way into Blackhawk. He finds someone attaching a thumbdrive to a computer and he tells him that if he does anything, things will "end badly" for him. But then! Diggle is there with a gun, telling Oliver to put the bow down! And I suppose I should mention that this guy is Ted Gaynor. And he's played by Ben Browder from Farscape, if you're into that sort of thing.
Oliver shoots a monitor, which explodes in sparks and stuff so he can escape without a scratch. Now that there's no bow-wielding vigilante, Ted offers Diggle a Job. Diggle asks why the vigilante would be after Ted, who doesn't fit the usual profile of the vigilante's targets. Because he's not super-rich. Ted doesn't really have an answer.
Diggle and Oliver reconvene in the Arrowlair so they can shout at each other about how dangerous it is to show up places and point weapons at each other. Oliver says his father explained to him that every name on the List had a reason to be there. He did? We never saw that. Diggle accurately points out that Oliver's father died before Oliver found the List. Oliver makes a radical new claim: "A few years ago, I found a message he left me, explaining the List." Oh, sure you did. Look, either everyone on the List is evil (so you should just hunt them all down right away) or you have to wait for them to break the law (so you need some kind of evidence on Ted Gaynor). Either way, if the show has decided what the List is, it's time to tell the viewers. Also, Oliver says he didn't say he found it on the island, so now Oliver seems to be claiming that he wasn't on the island the whole five years. Diggle says he's going to prove that Ted is innocent. Oliver clenches. That's how I'm going to describe it when he doesn't really have an expression but just tries to look really intense.
