While fans love to see the other heroes of the Arrowverse crossover to Supergirl every now and then, they don't necessarily like other characters upstaging her on her own show. Arrow will make a special one-time Monday broadcast airing at 9/8c on the same night!
Obviously, Tuesday, November 28 will be home to the final two parts, those being The Flash at 8pm and Legends of Tomorrow at 9pm. The Flash: Season 4 will begin airing on The CW on October 10, 2017 at 8 pm.
The biggest yearly event for DCTV is indisputably their massive crossovers. Indeed, despite the 2016 crossover's overall uptick, a good portion of the audience did not stick around for the conclusion; something The CW does not wish to repeat. "We felt in this particular case to [already] have Flash and Legends paired, it would be better and tighter in terms of storytelling to do a two-part miniseries". We thought this was a tight, concise way of doing it.More news: Danilo Gallinari fractures hand after throwing a punch during Italy game

One notable detail about the 2017 crossover is that it will likely be the first true four-way crossover event.
After last year's the much-hyped four-series crossover between the four Arrowverse shows turned into a three-night, four-show crossover (with the only scene from the crossover appearing on Supergirl replaying on The Flash, ), executive producer Andrew Kreisberg promised this year's would be a true four-series crossover.
The CW President also stated this year's iteration is "a full, four-episode crossover". However, it's still early enough for plans to change.
Whereas last year the #Arrowverse went up against the alien species called The Dominators, this year the superheroes might face some of their fiercest opponents allied together to defeat the heroes on a very special day: Barry and Iris's wedding. "If they end up wanting to go that way, that will be their decision". Will it be something major, like the time-bending 1994 comic book event Zero Hour?
