If the only way to save Sara is to kill you, then that's no cure at all.

Laurel

Lance: Sara's my daughter.
Laurel: Then why did I find you with a gun pointed at her head?

You know if I knew you were surrounded by so many pretty girls, Oliver, I would have stopped by sooner.

Constantine

Thea, I don't have the right to be mad at anyone for keeping secrets and I'm sorry that I made you feel as though you had to.

Oliver

New frequency, same cry.

Black Canary

A part of me has always wanted you to see what kind of man I really am! I didn't expect to wind up finding out what kind of man you really are.

Oliver

Oliver: Three years you've looked at me with contempt and utter disdain, so I'm wondering, do I have that look on my face now?
Lance: What the hell you talking about?
Oliver: I'm talking about you...and Damien Darhk.

Damien: I can give advice, father to father. If she were my daughter, I'd put her down.
Lance: She's my baby girl.
Damien: No, she isn't. She may look like your daughter, but she doesn't possess her soul. The most loving act you can commit is to return Sara to her final rest. I'm sorry.

Not to complain, but you do know you just brought a police captain into our SECRET lair?!

Felicity

Oliver: We're gonna need some money.
Felicity: Don't you mean more money?
Oliver: Mmmm hmmm.

Laurel: What did Thea think you weren't wearing?
Felicity: I have no idea.

You will be compelled to kill until you've slain the one who hurt you.

Arrow Quotes

Do you know why I always blame myself in situations like this? Because at least it's an answer. Sometimes we just need a reason when a situation is completely unreasonable.

Oliver

Laurel: Helena, you don't have to do this.
Helena: Yes, I do. Because once you let the darkness inside, it never comes out.
