Following the Justice League details and Gordon, Batman, Wonder Woman, Flash and Cyborg scene description, now a scene involving Barry Allen and Bruce Wayne becomes known.
It's already been said that the initial Flash costume will be made from spacesuit material held together by electrified wiring, and that by the end of Justice League, Waynetech will have created a new costume for the Flash.
This scene involves Barry Allen (Ezra Miller) returning to his apartment where he finds Bruce Wayne (Ben Affleck) already there. We also see in the ensuing dialogue that Barry makes a joke which references Gorilla Grodd.
Barry Allen's apartment is filled with all sorts of homemade tech. Bruce is sitting in a Lazy Boy chair waiting for him and has the convenience store security footage from Lex's files in Batman Vs. Superman.
JoBlo has the dialogue between Barry Allen and Bruce Wayne as follows:
BARRY ALLEN: “You must be looking for a person who looks exactly like me but is definitely not me. Somebody…I don’t know…hippie…long hair. A very attractive Jewish boy.”
Bruce shows him the camera footage which has Barry grabbing milk in the store.
BARRY ALLEN: “Well he drinks milk, and I don’t drink milk.”
BRUCE WAYNE: “I know you have abilities. I just don’t know what they are.”
BARRY ALLEN: “My special skills include viola, web design, fluent in sign-language, gorilla sign-language…”
BRUCE WAYNE: “Silicon-based sand coarse fabric. Abrasion-resistant. Heat-resistant.
BARRY ALLEN: “Uh yeah I do competitive ice dancing.”
BRUCE WAYNE: “This is used on the space shuttle to prevent it from burning up upon re-entry.”
BARRY ALLEN: “I ummm do…very competitive ice dancing. Look man I don’t know who you are but whoever you’re looking for, it’s not me.”
Bruce then quickly throws a Batarang at Barry as the environment goes into slo-motion except for him who easily catches the Batarang and makes the revelation that Bruce is Batman.
BARRY ALLEN: “You’re the Batman?”
BRUCE WAYNE: “So you’re fast.”
BARRY ALLEN: “That feels like an over-simplification.”
BRUCE WAYNE: “I’m putting together a team of people with special abilities. You see I think enemies are coming…”
BARRY ALLEN: “STOP! Right there. I’m in.”
BRUCE WAYNE: “You are. Just like that?”
BARRY ALLEN: “Yeah. Umm…I need friends.”
BRUCE WAYNE: “Great.”
BARRY ALLEN: looking at the Batarang “Can I keep this?”
