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.

Last time on Gotham, Jerome Valeska (Cameron Monoghan) encouraged mayhem in the city as the lights went out and the crazies followed. He went after Bruce (David Mazouz), taking him to a bloody carnival. Bruce managed to get in a bunch of punches, and then Jim (Ben McKenzie) punched his face off, literally. Bruce vowed, “I will not kill,” because he’s Batman. Jim’s Uncle Frank (James Remar) was in the Court of Owls, who were training the doppelgänger. After toying with his love the entire episode, Nygma (Cory Michael Smith) shot Penguin (Robin Lord Taylor) and pushed him into the harbor.

Last season on iZombie, the zombie secret was out… first to Clive (Malcolm Goodwin) and then to the rest of Seattle. Liv (Rose McIver) told Clive to help Major (Robert Buckley), who was in hot water for being the Chaos killer (even though he really didn’t kill anyone). Max Rager had a party that ended in a zombie rampage, complete with massacre, and Rob Thomas (wink wink) of Matchbox 20 bit the dust as well. Liv had to kill Drake to save Clive. Ravi (Rahul Kohli) found out about Blaine and Peyton (David Anders, Aly Michalka). The gang met Vivian Stoll (Andrea Savage), CEO of Fillmore Graves Enterprises, the company that just took over the now defunct Max Rager.

Last week on DC’s Legends of Tomorrow, The Legends headed to World War I where J.R.R.Tolkien (yes, that one) could point them to the Blood of Christ, needed to destroy the Spear of Destiny, which was now whole and whispering to them. They got the blood but lose the spear via Leonard Snart (not in Mick’s head). Mick (Dominic Purcell), sick of being on the outside, joined the Legion of Doom, and changed the fabric of reality. Many Lord of the Rings references splashed throughout this episode, including a speech by Rip (Arthur Darvill) clearly meant to inspire Tolkien.

Last week on Arrow, Oliver (Stephen Amell) was brutally tortured both physically and psychologically at the hand of Adrian Chase aka Prometheus (Josh Segarra). Chase was and is clearly insane, but he was able to break Oliver in ways that the other villains have not. He made Oliver admit that he enjoyed killing. That admission made Oliver put the blame of everything on himself (more than he usually does), and he returned to the lair to tell them it’s over. He quit.
