I've already seen you shirtless. Multiple times. Shirtless. All the time.

Felicity

Oliver: Would you like to go out to dinner with me?
Felicity: I'm being serious here, Oliver.
Oliver: So am I.
Felicity: I don't want to read too much into this, but are you asking me out on a date, like an actual date, like a date, date?
Oliver: Sure, I mean, usually the implication being with dinner...
Felicity: Usually I'm the one talking in sentence fragments.
Oliver: Would you like to go to dinner with me?
Felicity: Yes.

You catch 'em, I cook 'em. Oh! Did I say that too loud?

Laurel

Diggle: You love her. You even told her so.
Oliver: I was trying to fool Slade.
Diggle: Yes. Except now the only person you're fooling is yourself.

Keep this up and there will be two kinds of criminals left in Starling City. The ones we put away and the ones running scared.

Diggle

Felicity: Well, you did it.
Oliver: I had help.
Felicity: Yeah. It was really smart, the way you outfoxed him. Talk about unthinkable. You and me, I mean. When you told me you loved me, you had me fooled. For a second, I thought that maybe you might have meant it, what you said. You, you really sold it.
Oliver: We both did.
Felicity: Let's go home.

You helped me become a hero, Slade. Thank you.

Oliver

Lance: What am I going to tell your mother?
Sara: Tell her for the first time in my life I'm deciding my own fate.

You can kill me or not. Either way, I win.

Slade

The Mirakuru isn't what made me hate you! The end is near, but maybe I'll be merciful enough to let you live and see your city burn!

Slade

Oliver: You need to stay here.
Felicity: You can't just ask me to stay here.
Oliver: I'm not asking. I will come and get you when this is all over.
Felicity: No!
Oliver: Felicityyyy...
Felicity: Not unless you tell me why!
Oliver: Because I need you to be safe.
Felicity: But I don't want to be safe. I wanna be with you and the others. Unsafe.
Oliver: I can't let that happen.
Felicity: Oliver, you're not making any sense.
Oliver: Slade took Laurel because he wants to kill the woman I love.
Felicity: I know, so?
Oliver: So he took the wrong woman.
Felicity: Oh.
Oliver: I love you. Do you understand?
Felicity: Yes.

Lance: You've killed before. Tonight I suggest you get back in the habit.
Felicity: He's wrong.
Oliver: He's right.

Arrow Quotes

Oliver, sometimes the greatest act of love is no action at all. It's her life. It's her choice.

Malcolm

Oliver: Over watch, we're on sight.
Felicity: Excuse me?
Oliver: Well, I thought it was time you got a code name. What do you think?
Felicity: It's perfect.
Oliver: I was gonna go with Oracle, but it's taken.
