Supergirl Just Dropped a MAJOR Smallville Reference

The CW’s Supergirl drops a major reference to WB’s Smallville, hinting the shows may take place in the same universe. When the first season of Arrow debuted on The CW in 2012, many fans speculated whether it would hold up to Warner Bros. TV’s Smallville, which had just completed a 10-season run in 2011. Of course, Arrow did find success as its own DC Comics television series, and even helped The CW launch an entire universe of shows, which now includes The Flash, Legends of Tomorrow, and Supergirl. While the majority of the Arrowverse takes place on Earth-1, Kara Danvers (Melissa Benoist) resides on Earth-38 – largely because the show started its run on CBS before moving to The CW for its second season.

Season 2 of Supergirl went a long way to developing Kara’s world by officially introducing her superhero cousin Clark Kent aka Superman (Tyler Hoechlin) after only depicting the fellow Kryptonian in blurry or faraway shots in season 1. Superman has appeared in a handful of Supergirl episodes, but the show has made sure to keep its focus on its namesake. Still, we may have gotten some insight into Clark’s life – and how it potentially ties into Smallville – in the latest episode of Supergirl, ‘Midvale’.

Following the breakup of Alex Danvers (Chyler Leigh) and Maggie Sawyer (Floriana Lima) in the previous episode, Alex and Kara head to their childhood home in Midvale. However, much of the episode is a flashback to their time in high school as they try to the solve the murder of one of their classmates. When presented with a tech problem, Kara suggests they reach out to Clark’s friend Chloe – presumably Chloe Sullivan – and Kara even mentions Chloe’s Wall of Weird. Both of these are direct references to Smallville.
