Come February 23, and 'Supergirl' completes 100 episodes since its start in 2015.  Ahead of the episode, The CW released a preview of Episode 13: 'It's a Super Life', which sees the return of Mxyzptlk (played by Thomas Lennon), who offers Kara/Supergirl (Melissa Benoist) a chance to find out what it would have been like had she told her secret to Lena Luthor (Katie McGrath) instead of Lex Luthor (Jon Cryer). 

The Kara-Lena relationship has been one of the highlights of Season 5 and was followed by Arrowverse's epic crossover, 'Crisis on Infinite Earths'. Lena discovering that Kara was Supergirl ended the duo's friendship and with Earth-Prime being the result of the multiverse-shattering battle, she decides to work with Lex in the new reality that was formed. 

The official synopsis reads: THOMAS LENNON (“RENO 911”) GUEST STARS IN SUPERGIRL’S 100TH EPISODE – Mxyzptlk (guest star Thomas Lennon) returns with a proposition for Kara (Melissa Benoist) – what if she could go back in time and tell Lena (Katie McGrath) her secret before Lex did, would things turn out different? Looking back over key moments throughout the series, Kara must decide if she wants to change history to become friends with Lena again. Familiar faces return in this special episode. Jesse Warn directed the episode with story by Robert Rovner & Jessica Queller and teleplay by Derek Simon & Nicki Holcomb (#513). Original airdate 2/23/2020."

Ahead of the latest season, showrunner Jessica Queller in an interview with Comicbook had this to say about the duo's relationship: "I will just say that Season 5 revolves almost entirely around their relationship. I can't promise to make all of the fans' dreams come true, but if they care about the relationship between Supergirl and Lena they'll get a lot of it this year.

Back in July, Benoist described the season as a "fight for Lena's soul". And a fight it has been with Episodes 7 and 8 firmly focusing on the duo's relationship. 

'Supergirl' airs on Sunday nights at 9 pm ET/PT on The CW.
