Last time on The Flash, the new meta in town was Abra Kadabra (David Dastmalchian), a 64th century Flash-hating villain with Gypsy (Jessica Camacho) on his tail. He withheld Savitar knowledge. Barry (Grant Gustin) won’t free the murderer in a deal, but Joe (Jesse L. Martin) did. A fight and ensued and Caitlin (Danielle Panabaker) got speared with a pole, making surgery with no anesthesia and no doctor a necessity. Julian (Tom Felton) managed to do a decent job to no avail. Caitlin coded. Julian pulled off her protective necklace turning her into Killer Frost. Barry told Joe and Iris he was going to the future for answers.
