New Featurette for The Flash/Supergirl Crossover Released

A brand new featurette for The Flash/Supergirl crossover have been released. The special episode is called, “Worlds Finest” and it will air this coming Monday, March 28.

In the episode, “Kara gains a new ally when the lightning-fast superhero The Flash (Grant Gustin) suddenly appears from an alternate universe and helps Kara battle Siobhan, aka Silver Banshee, and Livewire in exchange for her help in finding a way to return him home”.

I love how giddy Melissa Benoist and Grant Gustin are for this crossover! They may be more excited than the fans!
