The Flash Season 5: 10 Easter Eggs & References You Might Have Missed In 'Nora'
2. Pre-Flashpoint Ralph
Now that Ralph Dibny is a fully-fledged member of Team Flash, he had some catching up to do. He may have been two or three years behind everyone else, but he did manage to grasp the concepts of time travel and the multiverse surprisingly well. In fact, he even jokingly suggested that, without Flashpoint, he could have ended up perishing in the particle accelerator explosion.
If you remember all the way back to Season 1, episode 7, it was revealed a person named Ralph Dibny did actually die on that fateful night. So when Ralph actually joined the show in Season 4, it caused quite a lot of confusion among fans. However, this throwaway line of dialogue has cleared things up, revealing that Elongated Man would not exist if Barry hadn't changed the timeline.
A neat little way for the show to tie up some loose ends.
