Supergirl is soaring higher than ever today on the news of an additional order of episodes from CBS. Only six weeks into season 1, and the superhero drama has just joined fellow newcomer and network alum Limitless with a full-season pickup. This brings the series' season 1 total to 20 episodes, which is actually two short of the usual full order (but who's counting?).
There's only one thing that could make this new deal even sweeter, and that's news of a Supergirl crossover with Greg Berlanti's other shows Arrow, The Flash and Legends of Tomorrow. Ever since the series was first announced, fans have been hoping to see Kara Zor-El join those other superheroes on the small screen. The Flash is already a spinoff of Arrow, and Legends of Tomorrow is a spinoff of the previous two, putting all but Supergirl in the same shared universe.
Yet two months ago at NYCC, when ScreenRant asked Supergirl creator and producer Ali Adler about a potential crossover, she admitted that they "actually haven’t talked too much" about the possibility. She did however say they would be "open to anything" once the show gets on its feet, leaving Bleeding Cool last week to report that a crossover between the shows in the new year would be dependent on whether Supergirl gets a full-season order.
And since the best place to find out more is always directly from the source, some reporters this morning during a press screening of this week's crossover between The Flash and Arrow took the liberty of asking Berlanti about the rumor directly. According to CBR, Berlanti dismissed the idea that discussions have already started for a crossover, saying: "No, only because we just received the pick up. Not at this point."
Now it's possible that there will be a crossover between The Flash and/or Arrow and Supergirl in the new year, but per Berlanti the planning stages haven't happened yet. Without knowing whether Supergirl would get more episodes, it would have been pointless to map anything out in regard to the three shows. That doesn't mean they hadn't thought about it a little and daydreamed, but any crossover that may happen at this point would have to be independent of whatever is already planned for The Flash and Arrow.
One presumes that at this point in the season, the writers for Berlanti's other shows already know where they plan to go through the end of the season. It's possible that Supergirl could drop by Arrow or The Flash, like Constantine recently did a few weeks ago, but not in a way that's too important for the plot. The second half of Supergirl on the other hand is a little more of an open book. Now that they have seven more episodes to write, almost anything could happen.
Supergirl continues tonight with 'Red Faced' on CBS @ 8 p.m. EST. The Flash episode, ‘Legends of Today,’ will air on The CW on Tuesday, December 1st at 8/7c. Arrow episode, ‘Legends of Yesterday,’ follows a day later on December 2nd at 8/7c. DC’s Legends of Tomorrow premieres on The CW on Thursday, January 21, 2016.
