The Flash Season 5: Flash vs Cicada

Following a cold open narrated by Nora — “I always wanted to be a hero…. That’s why I came here…. to save [Barry] from disappearing in the future… I never imagined it would turn out like this” — we picked up with Ralph leaping in front of the mirror gun blast that Barry was firing at the dagger. Ralph succeeded in preventing the dagger’s destruction (though Cicada II grabbed it and flew away), but he himself was worse for the wear, his cells “inverted” and leaving him in a, well, weird shape. A shard of wood left behind by Cicada II offers Team Flash a chance to track her. Back at STAR Labs, Sherloque solves the mystery of Ralph’s intervention — that the dagger is the only thing keeping Reverse-Flash in his future prison.
