Greg Berlanti and Ali Adler's Supergirl debuted its premiere season on CBS to some of the highest ratings of the Fall 2015 season. But, after a decline in ratings, the network moved Supergirl to The CW - which CBS co-owns with Warner Bros. TV - where the Girl of Steel's sophomore season will premiere alongside fellow Berlanti-created DC Comics series Arrow, The Flash, and Legends of Tomorrow.
Superheroes from all four series are expected to come together later in 2016 for a massive crossover, but before that unprecedented television event, each of The CW's four DC shows have their own respective storylines to introduce in their new seasons. With Arrow taking on more grounded villains, The Flash tackling Flashpoint, and Legends dealing with the Justice Society of America, we now have another hint as to what Supergirl may be facing in the show's second season.
On Instagram, Supergirl co-star David Harewood, who plays J'onn J'onzz a.k.a. Martian Manhunter, shared a photo of the script for the second season premiere, titled 'The Adventures of Supergirl' - similar to how The Flash star Grant Gustin, confirmed his show's third season premiere will be titled 'Flashpoint.' Take a look at Harewood's photo:
Of course, the episode title will likely remind Superman fans of the 1950s/1960s TV series, Adventures of Superman, or the Man of Steel's 1990s adaptation Lois and Clark: The New Adventures of Superman - especially considering the latter show's star, Dean Cain, has appeared on Supergirl as Kara's adoptive father Jeremiah Danvers. Plus, the CW series will be welcoming their own present day version of Clark Kent (Tyler Hoechlin) in the premiere episode.
But, it's more likely the episode title is a reference to the DC Comics digital tie-in related to Supergirl, called Adventures of Supergirl, written by Sterling Gates with art by Bengal. Or, like the episode title for the crossover between Supergirl and The Flash earlier this year, 'Worlds Finest,' it's possible 'The Adventures of Supergirl' is an easily recognizable reference to DC Comics characters, but not necessarily one specific property - even despite the nearly identical titles of the episode and Gates/Bengal's comic series.
Aside from the title of the Supergirl season 2 premiere episode potentially offering a reference to Cain's Man of Steel role on The New Adventures of Superman, a new interview with executive producer Andrew Kreisberg teases the actor's return to the now-CW series. Speaking to EW, Kreisberg hinted that Jeremiah may return in season 2, but viewers shouldn't take what they saw in J'onn J'onzz's vision of Project Cadmus from season 1 at face value:
“You should question everything. Until you see Jeremiah Danvers walk through the front door, everything can be questioned.”
So, between Project Cadmus, the official introduction of Superman, and the mysterious Kryptonian pod with an unknown occupant from the season 1 finale, Supergirl has plenty of ground to cover when the show returns for season 2 this fall. It remains to be seen how the show will be altered due to its move from CBS to The CW, but as long as Supergirl maintains what worked (and perhaps improves upon what didn't) the series will likely offer more fun adventures with the Girl of Steel.
The Flash season 3 will premiere Tuesday October 4th at 8pm on The CW, Arrow season 5 will premiere in the same timeslot on Wednesday October 5th, Supergirl season 2 on Monday October 10th, and Legends of Tomorrow season 2 on Thursday October 13th.
