Supergirl: Spoiler on the season 1 finale (Episode 1x20 "Better Angels") and scoop on the possibility of the show doing crossovers with Arrow and DC's Legends of Tomorrow from Entertainment Weekly's Natalie Abrams

Here's some scoop on Supergirl from Entertainment Weekly's Natalie Abrams' The Spoiler Room column, which was posted on 4/1/16.

Anything you can tease about the Supergirl finale? — Olivia J
Considering the Berlanti-verse has a penchant for killing off characters before the end of a season — Case in point: Who’s in the grave on Arrow?! — I asked executive producer Greg Berlanti whether we should expect death in the Supergirl finale. “Yes, you should,” he said, “only because it would be a lot less exciting if I said no.”

I loved the Flash-Supergirl crossover! Is there any chance of one with Legends of Tomorrow and Arrow included, too? — Karen
That’s certainly the hope, though the question would be how it’s feasibly possible. The good news is that the Legends may have a way to bring everyone over to Supergirl’s universe. “The Waverider can do [anything] and go anywhere,” EP Andrew Kreisberg reveals.
