The trailer for this episode of The Flash was out just a few days ago. From the trailer it is quite sure that Savitar is just not ready to leave our beloved superhero alone. Anyway, the episode will feature Barry accessing the Speed Force in an attempt/effort to rescue Wally. The problem that lies in the Speed Force is its complex labyrinth. So, finding Wally won’t be an easy as it sounds. Since Savitar is too powerful, he will have total dominance in the episode.
In the promo we also notice that Captain Cold is back from the dead. Well, that’s intriguing because Barry is facing his ghosts from the past. Dead enemies and other arch nemesis along with many loving friends who have been blown away with the sands of time will appear (probably, as per the teaser).
Throughout the preview, we see Eddie Thawne, Ronnie Raymond, and Leonard Snart. As we all can expect, Thawne and Raymond, both will blame Barry for their deaths. Apart from that, the trailer also reveals the return of Jay Garrick. Might be something interesting between him and Barry. The trailer even features a Time-Wraith; Barry gets attacked by a Time-Wraith, which is most likely some memory of the past that has come to haunt him. Well, he indeed messes up timelines too much. No surprise element in the Wraith haunting Barry.
