Supergirl’s move to The CW for Season 2 raised bigger questions than whether or not Superman would ever drop by, consider at least one mystery solved. The Martian Manhunter himself, David Harewood shared the official title for Supergirl’s Season 2 premiere, one that may just presage the arrival of a familiar face.

Soon gearing up to head to Vancouver (and subsequently Comic-Con 2016) for the second season of Supergirl, series star David Harewood shared the official premiere title over Instagram, ahead of its CW debut on Monday, October 10:

Let’s go. #SupergirlCW

Innocuous enough on its own, perhaps, but worth noting is that The Adventures of Superman served as the title of the original ‘40s radio show, followed by the George Reeves TV series. Comics have utilized the title as well, and even the formerly-CBS series has used The Adventures of Supergirl for its tie-in series.

We also know that Tyler Hoechlin will make his Superman debut in the season’s first two episodes, while Entertainment Weekly has some additional intel on erstwhile Clark Kent Dean Cain, specifically the mystery of Jeremiah Danvers in Season 2.

Hank had a vision of Jeremiah, but was it actually real? “You should question everything,” EP Andrew Kreisberg says cryptically. “Until you see Jeremiah Danvers walk through the front door, everything can be questioned.” As for why Jeremiah is locked up at Project Cadmus — if it’s really him! — we’ll find out why he’s so important in season 2.

Meanwhile, in addition to the introduction of Lynda Carter as this particular Earth’s POTUS, Supergirl Season 2 will cast several notable roles that include Lex Luthor’s sister Lena, DC police officer Maggie Sawyer and several others. Still unknown is if Supergirl Season 2 will introduce Superboy, given that mystery Season 2 cliffhanger, or how the Maiden of Might ends up in that epic four-way superhero crossover.

Supergirl has plenty other questions to answer on the road to Season 2, as well from Comic-Con 2016, but what can we expect from the premiere?
