Quick recap

Heroes from several Earths gather for Barry and Iris's wedding in Central City, which is crashed by soldiers from Earth-X, a world where the Nazis won World War II. They're led by Dark Arrow, Oliver's double, and Overgirl, Kara's double, with help from Eobard Thawne. Overgirl is dying, and the plan is to cut out Kara's heart to save her. Oliver, Sara, Barry and Stein end up in a concentration camp on Earth-X and are rescued by the resistance of Ray Terrill and Leo Snart. Martin Stein is shot and dies after getting home. Overgirl explodes in the sky, and Oliver kills Dark Arrow. In an impromptu ceremony, Diggle marries Barry and Iris, and Oliver and Felicity.
