The sixth episode of Black Lightning airs on The CW on February 27 and it is called “Three Sevens: The Book of Thunder.”
Here’s a description with some new spoilers:
TO RIGHT THE WRONGS – Jefferson (Cress Williams) is on the hunt for his father’s killer, while Anissa (Nafessa Williams) uses her new powers to rectify a wrong after a protest fails. Jennifer (China Anne McClain) grapples with some difficult choices. Elsewhere, Gambi (James Remar) begs for help from Lynn (Christine Adams). Damon Gupton and Marvin Jones III also star. The episode was written by Charles Holland and directed by Benny Boom (#106). Original airdate 2/27/2018.
UPDATE: The CW has now released some preview images — and for an episode subtitled “The Book of Thunder,” there’s a surprising lack of Thunder! Still some cool shots within, though.
