Thea: You know, I've been thinking a lot about Mom and Dad lately. Wondering what they would think about the lives we've chosen. All of the mistakes they made, all the lies they told in their own very, very messed up way. They thought they were protecting us.
Oliver: Well, they weren't, they didn't.
Thea: No, but it did help us become the people we are today. It turned us into heroes. We can't change the future Ollie. The past teaches us you might as well not bother trying to.
Oliver: When did you stop being my baby sister?
Thea: No, I never did. I just grew up a little bit.
