Before being found on a remote island, Oliver Queen was presumed to be dead for five years after a terrible shipwreck.
Prior to the shipwreck, Oliver was a wealthy and laid-back heart-breaker, without a care in the world. However, being on a deserted island changed him. While still pretending to be the man he used to be, Oliver goes by a different persona, Arrow, at night. As Arrow, Oliver tries to fight society's villains and restore his city to the way it used to be.
Diggle: Where ya goin'?
Oliver: To give a friend the benefit of the doubt.
Felicity: Stop! Oliver. I can't imagine how difficult this must be for you, but John is right. Thea lied.
Oliver: She lied about Merlyn, but Sara... I don't want to believe she could so something like this.
Felicity: Which is why you shouldn't be the one asking the questions.
