After the commercial, Deadshot hasn't fired. Officer Dad sees the lasersight on Walter. He tackles Walter and things start going crazy. Oliver makes Dig take "them!" out. He runs up the stairs and gets his stuff from a duffel bag he stashed on a landing. Deadshot keeps shooting people. Dig goes up the stairs after Oliver.
Oliver uses a grappling-hook arrow to enter the room where Deadshot is hiding. He's got a wrist-gun! Oliver doesn't shoot back right away, so Deadshot tiptoes around, looking for him. And that results in them fighting hand-to-hand, although Oliver is using his bow. They seem mostly even, but Deadshot throws the bow away.
They separate. Deadshot calls across the room, "I admire your work. Guess you won't be extending me any professional courtesy." Oliver claims he's only taken lives "for the good of others." Then he leans around a pillar and loses an arrow.
Deadshot's dead. There's an arrow through the goofy monocle I didn't mention. Dig gets to the room. He's got a shoulder wound. The curare!
Back on Flashback Island, Native Archer Island Oliver that this place is too dangerous for a man alone. "They'll kill you." He cuts down the net and vanishes. Oliver staggers away. Mysterious figures with machine guns study the net. This is a pretty busy deserted island!
Oliver drags Dig to his Arrowlair and mixes up some anti-curare drink. When Dig sort of comes back to himself, Oliver is unhooded. "Hey," he says.
