While Barry gets used to life without his powers, Wells decides to leave the lab and go in search of Jesse. Shortly after speaking with her, Wells is attacked and abducted by Griffin Gray, believing it to be Thawne, who demands that Wells find a cure for his metahuman abilities. Gray has superhuman strength, but also ages quickly. Barry discovers that when Gray uses his superpower, he accelerates the aging process. Barry, Joe, Cisco, and Jesse manipulate Gray into exerting their powers until he grows old and dies a weak old man; then his body returns to its 18-year-old self. To fight Zoom, Wells suggests recreating the circumstances that gave Barry his speed. Meanwhile, on Earth-2, Zolomon tells Caitlin that he kidnapped her because he is in love with her. Caitlin meets her doppelganger, the Killer Frost, who was captured by Zolomon as a reminder of Caitlin. Killer Frost convinces Caitlin to help her escape, but then tries to kill her. Zoom arrives and kills Frost's Killer, then warns Caitlin not to release the man in the Iron Mask. Hunter later decides to conquer other Lands in the multiverse and takes Caitlin back to Earth-1 with him.
