Supergirl season 5 episode 17 is set to arrive later this week on Then CW, with the title "Deus Lex Machina." This episode will be interesting since it will explore a different story of Lex Luthor, particularly how he came into power following the events happened in Crisis on Infinite Earths. This is a chance to learn more about him, as well as where and what he's been through.

In Supergirl season 5 episode 17, Lex proceeds to his plan to defeat the latest attack of Leviathan, pit Supergirl and her team against Leviathan, as well as bring Lena closer to him. It will also be revealed how he came into power after what happened in Crisis on Infinite Earths. This is an interesting episode since we're going to get Lex's backstory, which is completely different than what we've seen before.

The episode will explore the reasons and circumstances behind the latest rise of Lex. He's working with Brainiac and made himself as the best option of Kara to stop Leviathan and save the National City. However, his actions may not be enough even though he's adored by the general public once again. Lex is still out there, seemingly preparing himself to bring more chaos.

The episode will focus more on Lex and the things he did after the Crisis on Infinite Earths crossover event. There could be a new perspective coming here, but then, a new set of dangers might be looming around the corner as well. In addition, the episode could possibly set up more of what we can expect in the season's finale endgame.

Hence, viewers should be prepared for the chaos caused by Lex Luthor. Moreover, there could possibly be a major showdown with Leviathan. It's also interesting to see what Lex will do so he could bring Lena closer to him. But despite the apparent problems and chaos, the episode will still bring some interesting stuff along the way.

Meanwhile, Supergirl season 5 episode 17 is directed by Melissa Benoist, who plays Kara/Supergirl. The episode marks her directorial debut, so it's exciting to see how the episode will be different compared to the previous ones. Many were also delighted about this as the actress is directing a notable episode, one that may deliver a huge consequence in the future.

Supergirl season 5 episode 17 will be airing on Sunday night, Mar. 29, on The CW.
