SPOILER WARNING: This article contains major spoilers for "Lose Yourself," the latest episode of The Flash.
The Flash suffered a critical loss in "Lose Yourself," the latest episode. During a surprise attack from Clifford "The Thinker" DeVoe, the team lost both Ralph Dibney, aka Elongated Man, and Killer Frost.
Over the course of the episode, Barry and Ralph spent much of their time arguing the morality of killing DeVoe. Though Ralph seemed in favor of killing DeVoe, he couldn't bring himself to carry out the deed when push came to shove. That proved to be a fatal mistake for Ralph, who didn't properly fasten the anti-metahuman handcuffs he slapped on DeVoe. Just when Ralph thought he had won, DeVoe broke out of his cuffs and transferred his consciousness into Ralph's body.
Once DeVoe possessed Dibney, he launched an attack against Team Flash. He easily took care of Flash, Vibe and Killer Frost, but managed to strike another blow just before he left. Using Melting Point's power, he removed Caitlin's metahuman abilities, thereby erasing Killer Frost from existence. Cisco later confirmed this to be the case. Using a dark matter scanner, he revealed that all traces of dark matter had been removed from Caitlin's person.
By assuming Ralph's body, DeVoe has successfully gained the powers of every bus meta he created. Worse, Ralph's body has just what DeVoe needed: a physical form capable of sustaining his massive intellect. Thanks to Ralph's ability to shapeshift, DeVoe was also able to assume his true form, with actor Neil Sandilands reprising the role.
Now that DeVoe has made short work of the bus metas, he is another step closer to the Enlightenment. It is unclear what this means for the people of Central City, as the Enlightment has no direct analogues in the comics. However, it's probably nothing good, and Team Flash only has five more episodes to stop him and avenge their friends.
Airing Tuesdays at 8 p.m. ET/PT on The CW, The Flash stars Grant Gustin as Barry Allen, Carlos Valdes as Cisco Ramon, Danielle Panabaker as Caitlin Snow, Candice Patton as Iris West, Jesse L. Martin as Joe West, and Tom Cavanagh as Harry Wells, with guest appearances from Keiynan Lonsdale as Wally West and Hartley Sawyer as the Elongated Man.
