"I've just pushed some people and run away," Ezra Miller's Scarlet Speedster explains to the Dark Knight, presumably just as the team prepare to fight against Steppenwolf and his legion of Parademons. This humorous exchange between The Flash and Batman is perhaps a prime example of how the tone of this movie will differ from its predecessor, Batman v Superman: Dawn of Justice.

This featurette, released during the film's Flash Week promotion, also sees Miller discuss his character's powers and what they bring to the League. The actor explains that "Barry Allen is criminally excited to be a part of the Justice League," which is something that can be gleaned from all of the footage released so far.
