 * 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.

It only makes sense to have a discussion about the Supergirl crossover with The Flash! How'd everyone like this unique crossover?
