This was a really great episode that was so much fun to watch and see what they did with Barry and Nora going back in time to get items that could stop Cicada. And they did a lot of similar things to many other shows when they have 100 anniversary where it's like a recap of everything that led up to where they are now. But in this episode, it was done a lot better than in Arrow and in many other shows because of the fact that it had a solid storyline behind why they are recapping through everything. Now having Nora interactions with all the different villains that Barry has fought over the years was interesting with her reactions to everything. With her actually seeing things versus just hearing stories about what happened to her dad. By far the best scenes were the ones with Nora and Barry going to go and meet Thawne and him recognizing Nora but not fully which made for a fun moment of him sort of hinting for the Tornado Twins and Nora having to step in and be like no I'm not her I'm Nora. Which sort of help to fill the idea that there might be multiple timelines that Thawne is dealing with which would be interesting to see in the future how that plays out where there might be a different future where the Tornado Twins are a thing. Then how they got all the pieces together to make this device that helps to take the shrapnel out of Cicada so he can no longer have his powers was interesting with how they chose to lure Cicada in and what they did to hide the weapon from him until they used it. Then ending with the reveal that Thawne and Nora have a relationship together and that she does know him was really interesting to see the fact of Nora's reactions when she learns the truth of why Barry and Thawne have had such a bad relationship together. Then everything was Sherloque and him looking into whether or not they should trust Nora was interesting but I also feel like it could've been done better and it just felt like a random scene to get Sherloque and Iris in a fight. Then the reveal around the idea that Caitlin/Killer Frost can't be affected by the dagger because she's not a meta-human on the same wavelength as the rest is an interesting idea that she still has the ability to use her power and fight against Cicada makes it very exciting to see what they're going to do in the future. Then just overall this was a really entertaining and fun episode and I'm so excited to see what they are going to do next.
