How did they bring Lucifer back without anyone knowing! My mind was blown seeing him in Earth- 666 (haha of course) I loved it. He gave a reference to Maze which was cool, and if you told me that Lucifer would be a part of the Arrowverse a few years ago, I wouldn't be so sure. Overall, strong epiode with great cameos. With the second half of The Flash still needing to be shown, I knew he wouldn't die and that it would probably be another Barry Allen which it was (Earth- 90). Also, we knew Oliver would be back but it looks like when he really does go it'll be as a sacrifice to save the whole multiverse.
