Apart from the initial trailer, Supergirl’s imminent Flash crossover let fly a few quick clips in a behind-the-scenes featurette, but the real deal has arrived, every bit as adorably as you dreamed. Watch super-sparks fly (with plenty of Arrow, Legends references and meta-humor in our longest look yet!
CBS released four full clips from Monday’s crossover, included among them a first confrontation between the two heroes (peppered by Barry name-dropping about every DC hero on The CW), and later Barry explaining alternate realities to Supergirl’s team. The first meeting with Cat Grant gets a solid zing at The CW, while the fourth puts together Livewire and Silver Banshee.
So reads the official March 28 synopsis:
Kara gains a new ally when the lightning-fast superhero The Flash 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.
We’ll see for ourselves on March 28, so stay tuned for more “Worlds Finest” details of the big Supergirl-Flash crossover!
