First up, on Supergirl, Kara (Melissa Benoist) will face-off with Psi (Yael Grobglas), a psychic thief that immobilizes his foes by tapping into their worst fears, which doesn’t seem like it’s going to go well for our Girl of Steel. Then, on The Flash, Barry has to attend couples therapy while also trying to take down a dangerous new meta that can control technology. Then, we go back to the past on DC’s Legends of Tomorrow where Nate and Ray find themselves in big trouble after they accidentally free a saber-toothed tiger. And finally, on Arrow, Oliver tries his best to be a father and Anatoly returns to Star City.
