With Supergirl joining, officially, the CW Network this Monday, it seems while she will be crossing over into the Arrowverse, it seems that her world will still standalone compared to everyone else on CW Prime. That is what I am calling the original CW shows that spunoff from Arrow. Last week, we saw The Flash and Arrow debut their third and fifth season respectively, but fans have been waiting to see how Supergirl figures into the whole universe.
Executive Producer Andrew Kreisberg told Entertainment Weekly, “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.”
The internet, during the past intervening months, had some theories as to how Kara’s universe would join the main CW universe, many of which were spawned by the alternate reality Barry created during The Flashpoint episode on The Flash. What a surprise that internet rumors turned out to be untrue.
It isn’t a complete shock that Kara’s universe will remain on their own, while everyone from the other three CW/DC series mingle all the time. However, with the series moved to Vancouver with the other shows, mingling between dimensions will be a lot easier than it was in the first season of Supergirl. So this should still prove interesting.
