“A Flash of the Lightning” is the second episode of the sixth season of The Flash, and the one-hundred-sixteenth episode overall. It aired on October 15, 2019. This episode is also the second in a subset of the sixth season episodes the writers dubbed as “Blood and Truth.”
Plot
Starting where we last left off, Barry and Iris have a conversation about what just happened, and Iris convinces Barry that what crap The Monitor said and schemes to change the timeline. Barry gets the idea to travel to the day after he vanishes.
Later, Barry travels to the future but is blocked by a wall of Anti-Matter and is sent out of the timestream and gets help by Iris; Gideon suggests Barry go to meet up with Jay Garrick on Earth-3.
Cecile, Joe and Criminal Allegra Garcia
are in a room talking about Allegra’s current situation, and Cecile lets Allegra go free on a condition of Meta Cuffs.
On arrival, Jay helps heal Barry and agrees with Barry’s decision to Time Travel. Jay’s Wife Joan Williams, who looks like Barry’s mother. Barry and Jay work together and sends Barry’s mind through the barrier, he sees billions of future’s and timelines. He sees one where he must die to save everyone, proving The Monitor right.
Back on Earth-1
Ralph and Iris find Allegra with a dead body and assume she is the one who did it. Joe later arrests her sending her back to CCPD where Cecile rushes in and bargons with her, and Allegra reveals that it wasn’t her, and Esperanza Garcia/Ultraviolet – her sister. Who was meant to be “dead”.
Barry returns to Earth-1 and talks to Joe, and later faces Esperanza and stops her.
Later, Barry vows to prepare Team Flash for Crisis.\
Behind the Scenes
Despite Barry only seeing a victory against the Crisis needing him to die, the fact there was more episodes for Flash’s Post-Crisis era proved that he would survive.
Not to mention that the Barry Allen of Earth-90 was confirmed to appear during the Crisis on Infinite Earths event. These two facts unfortunately made it quite easy for fans to figure out the surprise the writers planned.
After the episode’s premiere, The Flash Twitter account tweeted a Behind the Scenes still that never made it into the final airing that of Iris making it to S.T.A.R Labs as Barry recovers after his encounter with Ultraviolet at CCPD.
When the Season was released on DVD and Blu-ray, the deleted segment was not featured therefore rendering the scene lost.
Lightning
Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions, both in the atmosphere or with one on the ground, temporarily equalize themselves, causing the instantaneous release of as much as one gigajoule of energy
