CBS Supergirl Spoilers: Twitter Reacts Melissa Benoist, Grant Gustin The Flash Crossover Twist

CBS and the CW Network aired the highly anticipated crossover between DC Comics' Supergirl and The Flash. Twitter had lots to say about Kara Danvers (Melissa Benoist) and Barry Allen (Grant Gustin) meeting for the first time in the episode of Supergirl.

In our recent recap, Silver Banshee (Italia Ricci) unleashes her sonic powers at Kara and threw her out the window. Tearing through a portal, The Flash caught Kara, but quickly realized she didn't need saving. Asking for her help to return home, The scarlet speedster worked with Supergirl to take down Silver Banshee and Livewire (Brit Morgan) after they had kidnapped Cat Grant (Calista Flockhart). After the two superheroes worked together, Supergirl kept her promise and sent the scarlet speedster back home. But could have The Flash stayed longer to help Supergirl with her impending alien invasion?

In an interview with TV Guide, executive producer Greg Berlanti explains how the crossover came about, "You wanted [Supergirl] to work and stand on its own on CBS and have its own audience. We thought we might wait until the second season, but we came back after Christmas and were planning out the final third of the year and we saw a way we thought we could do it. It felt like the right time for him to enter her world and help her out. It all came together. "
