Tonight we attack the thinker? Will our heroes win? Seeing as there’s 6 episodes left in the season I kinda doubt it, but let’s give them a chance to entertain us. Let’s react!

Info: RALPH CONSIDERS CROSSING A LINE TO DEFEAT THE THINKER — When Barry (Grant Gustin) and Team Flash find a way to enter The Thinker’s lair, Ralph (guest star Hartley Sawyer) considers crossing a dangerous line to defeat DeVoe. Meanwhile, Joe (Jesse L. Martin) is concerned by Harry’s (Tom Cavanagh) recent behavior. Hanelle Culpepper directed the episode written by Jonathan Butler & Gabriel Garza (#418). Original airdate 4/17/2018.

The promo looks extra serious.
