"We are so incredibly excited to announce something that we have dreamed of happening since we starting making Supergirl - The Flash and Supergirl are teaming up! We want to thank Grant Gustin for making the time to come visit (on top of his already immense workload) and all of the folks at CBS, The CW, Warner Bros. and DC for working this out. And finally, thanks to the fans and journalists who have kept asking for this to happen. It is our pleasure and hope to create an episode worthy of everyone's enthusiasm and support."

Ever since Supergirl was picked up by CBS, fans had wondered if it was possible for this series to cross over with Greg Berlanti and Andrew Kreisberg's shows Arrow and The Flash on The CW. While they do air on different networks, both CBS and Warner Bros. Entertainment actually own The CW, with the network's name actually a combination of the first letters of its parent companies.
