Supergirl S06E17 Preview: Lex Feels Like He's Seen This All Before

On tonight's chapter of The CW's Supergirl, Kara (Melissa Benoist) and Team Supergirl have a double dose of deadly danger to deal with now that Lex Luthor (Jon Cryer) and a Nyxly (Peta Sergeant) tag team. So it's easy to understand why Alex (Chyler Leigh) is having a hard time finding the right time to propose to Kelly (Azie Tesfai). But just in case you need a little more convincing of just how five-alarm things have become, maybe a fresh look at "I Believe In A Thing Called Love" will convince you.

Supergirl Season 6 Episode 17 "I Believe In A Thing Called Love": LEX RETURNS – When Lex Luthor (guest star Jon Cryer) appears by Nyxly's (Peta Sergeant) side, Supergirl (Melissa Benoist) and the team must deal with the emotional fallout of facing their two biggest foes at the same time. Alex (Chyler Leigh) makes plans for the perfect proposal to Kelly (Azie Tesfai), but work keeps getting in the way. Directed by Jesse Warn and written by Dana Horgan & Nicki Holcomb.
