The Flash will be able to travel to the alternate Earth that Supergirl lives on, but she will not be able to return the favor.
This event pays homage to DC Comics history.
Rebirth--Why the New 52 did not work!
DC Comics has announced that they will be undertaking another company-wide reboot of all their comic book titles this June

Nightwing--DC Comics most popular hero (that some people don't know)!
Grayson has always been a “chick magnet”.
He’s fought everything from common street thugs, to Blockbuster (who could arm wrestle the Hulk), to Trigon the demon alongside the Teen Titans.
Supergirl--Why Not?
Wonder Woman is a hero in her own right but characters like Supergirl were created to be a spinoff of an already popular character like Superman?
The show is such a classic superhero tale, male or female!
