Spoilers ahead of The Flash season 8! 

The Flash season 8 “Armageddon, Part 3” dealt Barry a pretty critical blow when it was revealed who’s been messing with the timeline and affecting his present: Eobard Thawne, Barry’s petty nemesis who came up short in speed compared to him in the season 7 finale.

Thawne is the reason why Joe died prematurely, and he’s been dismantling Barry’s life piece by piece. Comics fans of The Flash undoubtedly picked up hints about this story as the crossover event went on and that will continue to be the case in “Armageddon, Part 4.”

We last left the series on a disturbing cliffhanger as Barry witnessed a party celebrating Thawne’s love for Iris. The Reverse Flash has crossed many a line over the years and this one was truly a gut punch and a stab directly in the heart.

What will Barry do next? Find out tonight on “Armageddon, Part 4.” Here’s when the episode premieres along with its synopsis and how to watch it live online.
