Did You Know?


Barry suggests that Nora could "Marty McFly herself out of existence", referring to the protagonist of the 1985 film Back to the Future, who accidentally interferes with his parents' first meeting whilst traveling back in time, nearly erasing himself from existence. Iris confidently recognizes the reference being from the film Terminator 2: Judgment Day, before Barry begins to correct her. See more »


Caitlin says that Gridlock's powers won't work in zero gravity because zero-G means no kinetic energy. Bodies have kinetic energy by virtue of being in motion and bodies can certainly be in motion in zero-G. For example, astronauts. See more »

Nora West-Allen: Okay, let's back up. My name is Nora West-Allen, the fastest woman alive. When I'm from, 30 years from now, I'm the guardian of Central City. I'm a speedster, just like my dad. People call me XS. Every day, I hope to live up to the legacy of The Flash... But I've still got a long way to go.
