Diggle: I see you brought your plus one.
Ray: Nice to meet you. Ray Palmer.
Diggle: John Diggle. [whispering into Ray's ear] You hurt her, they'll never find your body. [louder] Nice to meet you!

Oliver: He said I can do more as the new Ra's than I could ever do as Oliver Queen or the Arrow. That I would have unlimited resources. That I could make a difference, not just a dent.
Diggle: You aren't really considering this, just because Capt. Lance is angry and Felicity is momentarily unavailable?

Diggle: So, pretending for a moment that we aren't two dead men chained to the floor, how do you feel about being my best man?
Oliver: I feel pretty good about it.

Listen, I know what you're doin' and I know why you're doin' it, but you can't save Thea's soul at the thought of your own.

Malcolm: John?
Diggle: My friends call me Dig. You? Shouldn't even talk to me.

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?

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: 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.

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

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.

Felicity: What's going on? Ray?
Ray: Oliver Queen is the Arrow.
Felicity: What?
Ray: I have a 140 IQ and three PhDs, but it's pretty hard to insult my intelligence, but I'm pretty sure you just did. It all makes sense now. Your, ah, sudden disappearances, your apprehension of helping me with my mission. You've been working with the Arrow this whole time.
