Supergirl S06E17 Preview: Deadly Double Trouble for Our Super Friends

While we're pretty sure that viewers of The CW's Supergirl were happy to see his villainous face return for the show's final season, we're definitely sure that Kara (Melissa Benoist) and Team Supergirl would've preferred that Lex Luthor (Jon Cryer) just send his regards via an Edible Arrangement. But no, that's not the case as we head into this week's episode "I Believe In A Thing Called Love" as Lex teams with Nyxly (Peta Sergeant), creating a nearly unstoppable pair. And in the midst of all of this, Alex (Chyler Leigh) waits for the "eye of the storm" to kick to have a moment of peace to properly propose to Kelly (Azie Tesfai)- as you're about to see in the following preview images, episode overview, and promo for this week's chapter:
