Laurel, we'll know. I know this doesn't count for much but, me and Lyla, we're naming the baby Sara. We will never forget.

Oliver: John, I don't want to die down here.
Diggle: So don't, Oliver.

This thing with Palmer, it's messing with his head, Felicity, and that's dangerous.

Diggle: If this is an ARGUS thing, Lyla's gonna want it to stay that way.
Oliver: Then tell her to stop letting people get killed in my city.
Diggle: You really don't care about my marriage, do you?
Oliver: Well I would, if you and Lyla were still married.

Lyla: You only call me sweetie when you want something.
Diggle: Is it working?

Cisco: Are you OK?
Diggle: My daughter's mother tried detonating a bomb inside a man's head and now he's trying to kill her.
Cisco: So that would be a no.

Diggle: I'm more of a glock kind of a guy.
Roy: I didn't say anything.

Diggle: OK. The point is, if we're going to do this without Oliver, Felicity, we have to trust each other.
Felicity: You don't get it. There is no 'this' without him. It's done. I'm done.

Diggle: He's not coming back, Oliver. I know you don't want to believe it, Laurel, God knows I don't but, he's not coming back.
Laurel: Are you? Are you coming back?
Diggle: I don't know. For the first time since I met Oliver Queen I don't know what happens next. I know it's silly, but I still like to think of myself as Oliver's bodyguard. I just couldn't protect him. It's funny. He was worried something would happen to me.

Diggle: That's just the thing. Once we let the ends justify the means, that's just the first step.
Malcolm: Towards what?
Diggle: Becoming you.

Roy: You think you're the only person who can stand up for Thea?
Oliver: I'm trying to figure out why you're standing up to me!
Diggle: Alright. Maybe we just need to throttle back.
Felicity: No! We need this. Oliver, you were gone, dead, at least we thought you were, and we had to go on with our lives and doing that meant not doing things your way.
Oliver: Fine. I'm back now!
Felicity: That doesn't mean we can go back! And you do not have the right to come back here and question everyone's choices.

Diggle: No, you weren't gone. You were dead and all of us, including me; we were ready to hang it up.
Oliver: Why didn't you?
Diggle: Because we realized we weren't just fighting for you, we were fighting for ourselves. That includes Roy and, yes, that includes Laurel.
Oliver: She's not a soldier.
Diggle: Neither were you.
Oliver: It's not the same thing and you know that.
Diggle: What I know, Oliver, is that you started something, something strong enough to live on past you. Question is, can you live with what it's become?

Arrow Quotes

I thought you took that book off your father's dead body. How could he have been so chatty?

Diggle

She was my sister. I couldn't be angry because she was dead. I couldn't grieve because I was so angry, that's what happens when your sister dies while screwing your boyfriend.
