Bruce Wayne: "So you're fast."
Barry Allen: "That feels like an oversimplification."
Bruce Wayne: "I'm putting together a team, people with special abilities. You see, I believe enemies are coming..."
Barry Allen: "Stop right there. I'm in."
Bruce Wayne: "You are? Just like that?"
Barry Allen: "Yeah. I... I need friends."
Bruce Wayne: "Great."
Barry Allen: "Can I keep this?"

"Bruce! Listen to me now! It's Lois! Lois Lane! She's the key! Am I too soon? I'm too soon! You were right about him! You've always been right about him! Fear him! Find us, Bruce! You have to find us!"

Bruce Wayne: "Barry Allen. Bruce Wayne."
Barry Allen: "You said that like it explains why there's a total stranger sitting in the dark in my second favorite chair."

Barry Allen: "Wonder Woman... What do you think, man? You think she'd ever go for a younger guy?"
Cyborg: "She's 5,000 years old, Barry. Every guy's a younger guy."

Barry Allen: "What are your superpowers again?"
Bruce Wayne: "I'm rich."

Barry Allen: "You have a satellite?"
Bruce Wayne: "I have six."
