I know everything from Arrowverse but I am not following Supergirl. Only checked it's leaked pilot. Do I need to see the whole Supergirl till the crossover or is the basic knowledge of Supergirl + pilot episode enough to understand the crossover episode?

    Nah. All you really need to know is that Supergirl's gained a bad reputation after going a bit crazy (due to red kryptonite). There's a lot of other plot going on that you'll be unaware of (Kara's ill-chosen romantic triangle) but nothing you'll notice or really care about.

  • To be honest, I'm not sure you need to watch the crossover episode to get any additional story for The Flash, so you could give it a miss entirely. Commented Apr 13, 2016 at 12:08
  • @AnthonyGrist - Agreed. It's a completely self-contained episode from his perspective. He doesn't bring anything back with him, physically or emotionally.

Yes. The episode doesn't go into much lore, and the basic premisses are explained to the Audience via explanations to The Flash/Barry.

The biggest issues would be:

How/Why Livewire became Livewire, why Silver Banshee hates Kara, and the bulk of the Kara/Jimmy UST.

But Callista Flockhart's character sums those up nicely (well, condescendingly) as well.
