Felicity Smoak:
But there is one thing I need to ask you to do. And you're not going to want to.

Oliver Queen:
Well, if it's you asking, I'll do it.

Felicity Smoak:
Kill him. You have to kill Ra's al Ghul. This is a duel... Oliver, with one of the most dangerous men that has ever walked the Earth.

Oliver Queen:
I wouldn't be doing it if I didn't think I can win.

Felicity Smoak:
I don't doubt that. I don't doubt that you can beat him. I am terrified that you won't kill him. Because that's not who you are anymore. And I am so afraid that Ra's al Ghul will use your humanity against you.

Oliver Queen:
Felicity, I honestly don't know if I'm a killer anymore. But I do know two things - the first is that whoever I am, I am someone who will do whatever - *whatever* - it takes to save my sister.

Felicity Smoak:
And the second thing?

Oliver Queen:
I love you.
