Barry taking Wally along with him into the Speed Force for the first time…

Barry: Where we’re going, we don’t need roads.

Getting caught in an argument between Bruce and Clark at the Watchtower…

Hal: So, who’d you side with?

Barry: Neither. I just pretended we were telepathically paged by J’onn. And then when they said they didn’t hear anything, I called them both liars and zoomed away.

Hal: Smooth.

Hal: I got you a present for your trip to Mexico with Iris. It’s my old Spanish to English dictionary. I don’t need it anymore. I’ve mastered the language.

Barry: Gracias, Señor.

Hal: You’re welcomo.

Pillow talk at the Allen home…

Iris: Do you ever think about the future?

Barry: Yeah, I think about the future.

Iris: Am I in it?

Barry: You are my future.

Iris: Honey, you are about to get so lucky.

Hal: I am an excellent secret keeper. I have kept all of our secrets.

Barry: What secrets?

Hal: Oh no, no, Barry. I am not going to tell you because I am an excellent secret keeper.

* Wonder Woman, Black Canary, and Hawkgirl leave the room *

Barry: You’ll tell me later?

Hal: You already know.

[INJUSTICE 2] Pre-Battle Banter

Barry: You’ve gotta lighten up a little.

Bruce: What part of “Dark Knight” don’t you get?

Barry: See? That’s just what I’m talking about.

[INJUSTICE 2] * Pre-Battle Banter *

Barry: Hitting me won’t be easy.

Bruce: It’ll hurt just the same.

Barry: Couldn’t you be intimidated just this once?

After a Justice League meeting at the Watchtower…

Hal [to Barry]: Well, how do you know he’s even in a bad mood? It’s impossible to read that guy.

Bruce [Flashback, to Hal]: This is the most incompetent, worthless report I have ever read in my life. Get your act together, Lantern, or so help me, you won’t live to see the next crisis.

Hal: It’s like, what’s the guy thinking? You know?

Hal: I’ve never seen Bruce look so upset before. He looks like a sad block of granite.

Barry: What are we gonna do? How do you cheer up granite?

… Maybe that’s why we get along. You see the good in me, I see the bad in you.
