The 18th episode of Supergirl will be one Superhero event as it'll be the first crossover episode between Supergirl and The Flash. The epic crossover will happen on March 29th. Here is the official synopsis of Supergirl episode 18:
“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.”
How excited are you to see Barry Allen (Grant Gustin) with Kara (Melissa Benoist). You know what I'm thinking? Will they sing together? They're both from Glee, duh! For more entertainment updates follow me on Twitter, Instagram and Periscope. SUBSCRIBE on my You Tube channel for exclusive videos.
