In the episode entitled “Worlds Finest,” Supergirl joins forces with a lightning-fast—and super dreamy—hero, The Flash to take out two villains. Lost and confused after spiraling from his universe and landing in Kara’s, The Flash asks for her help in finding his way back home. Kara agrees on one condition: The super-runner has to help her take down her ultra-competitive co-worker and screeching malefactor Siobhan, aka Silver Banshee, and Supergirl’s old nemesis, Livewire.
CBS promises an episode packed with action and a bit of super-flirting. ‘Worlds Finest’ premieres Monday, March 28 at 8/7c.
