Review: The Four-Show Crossover Begins With Supergirl’s “Medusa”
Supergirl has had a very interesting season thus far. Dealing with themes relating to xenophobia, gun control, and LGBTQ rights, the show has leaned heavy into social commentary, and it's done so without being too preachy or biased. Likewise, a few huge characters from DC Comics have made their introductions on the show, such as Miss Martian, Cyborg Superman, and Mon-El. This week, things get even more interesting as the four show crossover, Heroes vs. Aliens, finally begins.  

The episode, dubbed "Medusa," actually has very little to do with the arc of the crossover, however. Instead, it focuses on a certain virus that CADMUS develops from Supergirl's blood, which they try to use to wipe out all alien life on Earth. Hank Henshaw, or Cyborg Superman, disperses the first dose in the alien club that the team has been frequenting, killing several aliens and poisoning Mon-El, who's out of commission for the larger part of the episode. The DEO works to find a cure as Supergirl tries to track down Lena Luthor's mother, the leader of CADMUS.  

Supergirl goes to Lena first, and she acts very defensive of her mother. As CADMUS is in need of a certain isotope from L-Corp to disperse her drug, Lena then contacts her mother and says she's ready to join the cause. The twist at the end, however, is that Lena essentially deploys a cure to the virus instead, which also heals J'onn's White Martian poisoning. When everything is said and done, Barry and Cisco journey through the multiverse to ask Kara for her help.  

"Medusa" actually proves to be one of the better episodes of Supergirl season two. The twist with Lena is well played, and getting to see J'onn go berserk as a White Martian, knowing that the condition is only temporary, is actually quite fun. Likewise, the humor and heart of the show work together nicely this week, as Mon-El and Supegirl get increasingly adorable to watch interact, and a touching moment between Alex and Maggie caps off the episode.  One of the only downsides (except for Supergirl's ever-present lack of quality special effects) is that the episode really isn't part of the crossover, as was advertised; Barry and Cisco only make a brief cameo in the final scene.

Still, "Medusa" is a worthy entry into Supergirl's sophomore season. The social commentary still underlies the main struggle, which is a nice change of pace from the other CW shows, and having the tension of knowing Barry and Cisco would be on their way at some point actually seems to work for the episode. The story continues tomorrow, however, as Supergirl enters the Earth-One universe for the very first time.  

The Heroes vs. Aliens crossover continues tonight through Thursday, 8 p.m. each night on the CW.
