Anyone who knows Archie comics knows the Riverdale gang has met just about every other comic character, so might Riverdale itself follow suit? A new set photo from Season 2 of the CW hit seems to show Supergirl hanging out in Pop’s Chock’lit Shoppe, so what does it mean?

Creator Roberto Aguirre-Sacasa dropped a cryptic new tease of either series’ return, showcasing suited-up Supergirl star Melissa Benoist joining Betty (Lili Reinhart) and Veronica (Camila Mendes) for milkshakes. Before we start speculating that Riverdale takes place on Earth-38, or that Barry somehow royally messed up the timeline again, we’d guess the appearance belongs to a fall CW promo, just as we’ve seen Supergirl joining Arrow and The Flash for some promo fun:

That said, Riverdale Season 2 is said to skew a little more supernatural in its second season, so flying Kryptonians may not be so out there as they seem. Perhaps Supergirl even dropped by in search of Brit Morgan; actress behind National City shock jock Livewire, who plays “snake charmer” Penny Peabody in Riverdale Season 2.

In the meantime, Riverdale Season 2 will premiere on Wednesday, October 11, while Supergirl returns two days prior on October 9. Watch the Riverdale Season 2 trailer below and stay tuned.
