Sara and Black Siren in “Unfinished Business”

Sara

Look, I don't know what you've heard about me, but basically, I had an affair with my sister's boyfriend, I allowed my family to think that I was dead, and then I became a league-trained assassin.

Black Siren

Wow. That's impressive.

Sara

My point is even with someone with a past as checkered as mine can still turn their life around, can be a hero.

Black Siren

I was being a hero. I was the D.A., I got Oliver out of prison, and I was the only one who figured out that his little sister was basically the Devil, and they still turned on me.

Sara

So, what, you think you deserve a medal for trying to be good for 5 seconds? Redemption isn't a destination. It's a journey. I wasted years running away from all the bad things that I had done because I didn't want to face the pain that I caused because I didn't want to be that person, and I realized the only way to stop being that person was to come home and own up to things I had done, and, yeah, it was painful, and it took a really long time, but it was the only way to become someone else, someone better than who I was.

Black Siren

Well, that's great for you, but even if I wanted to change, it's a little bit too late because this is who I am.
