Oliver Queen: I spoke to Laurel.
Felicity Smoak: When did she become Laurel? She's not Laurel. Not "Laurel" Laurel. She's not our Laurel, okay? Not...
Oliver Queen: Okay, Felicity, I'm... I can't pretend to understand parallel worlds. But if I'm going to believe in them, and... and I kind of have to now, then I need to believe that differences are caused by circumstances. So why can't we change this Laurel's circumstances?
Felicity Smoak: You think that you can save her? After she's thrown in with Prometheus?
Oliver Queen: Under duress. I just... I think I can reach her.
Felicity Smoak: When did you find the time to get a PhD in psychology?
Oliver Queen: I'm a quick study.
Oliver Queen: Why didn't you come to me with this?
Laurel Lance: Come to you for what? Your expertise with magical resurrection? Or that judgmental look on your face?
Oliver Queen: For help finding your sister, Laurel, before she gets hurt, or she hurts anyone else. And If I have a judgmental look on my face right now, it's because you played with forces that you do not understand, and now people are dying because of it.
