So in an interview with one of the writers on Black Lightning who is excited to be working with Gred Berlanti. She answered the question we all are asking. Is it connected to the Arrowverse?
She basically said that we need to let the audience know more about Jefferson Pierce before we have him team up with other heroes. Then have him be established in a universe that is part of that whole world.
So this just confirms that after the first season, we should see him be a part of the multiverse at some point. Some sort of Earth. Probably Earth-7 considering that the trailer for the show told us that 2007 is when Black Lightning started his career. Do you guys think differently though? Do you think he'll be in this world at some point? Put it down below.
