John Diggle: You got something?
Felicity Smoak: Yeah, an apology. I never should've let you think that you could have prevented what happened to Laurel, not even for a second. I was just dealing with my own guilt for not being there.
John Diggle: You have nothing to be sorry about, Felicity. If I had listened to Oliver and not trusted my brother, Laurel would be alive.
Felicity Smoak: No, you don't know that.
John Diggle: Oliver keeps saying the same thing, except I keep going through this over and over again in my head and it-- It's true. Only thing I don't quite get is how I could have been so blind.
Felicity Smoak: Well, Andy's your brother, you know? We make exceptions for family.
John Diggle: Yeah, and I'm the one constantly telling Oliver not to have a blind spot for family.
Felicity Smoak: And here you are, taking the blame for something that's not your fault. You're just one illegitimate child away from a really awesome Oliver Queen impersonation. But just like we tell Oliver, what happened was not your fault, and Laurel would have wanted you to know that.
