The Flash Season 3: 10 Big Questions That Must Be Answered
9. What Will Happen In The Four-Way Crossover?
Supergirl is coming to The CW!
That's pretty exciting, for while the debut season of the Girl of Steel's solo show was a bit of a mixed-bag, it means we are going to see a four way crossover between Supergirl, Arrow, The Flash, and Legends of Tomorrow.
Typically the Flash/Arrow crossover events have taken place over consecutive nights, which means we should perhaps expect an event spanning four episodes - rather ambitious, but it could be amazing if they pull it off.
The big question is what exactly will happen though - what possible threat or moment could bring all of these characters together? Will it be a big villain, or could it be as a result of Flashpoint? Speaking of which, how will that affect the other shows? They all exist in the same universe, so theoretically should all undergo major changes, but it remains to be seen how far they'll go with that.
