When it was announced that there would be a four part crossover between all for DC Comics shows on The CW and that The Flash would be exploring Flashpoint, it made a lot of fans theorize that the universe Supergirl was apart of would merge with the rest of the DC shows on The CW.
Now in an interview with Entertainment Weekly, executive producer Andrew Kreisberg has put to rest anymore theories and has bluntly said they will not merge.
As revealed during The Flash-Supergirl crossover last year, Supergirl hails from a different universe. Are you planning on bringing Supergirl into our universe?
Not for her entire world, but Kara will be traveling from her dimension to our dimension, “our” being the world that The Flash, Arrow, and Legends lives in.
