'Supergirl' Season 5 Episode 17 'Deux Lex Machina' Preview: When will Lena realize Lex is manipulating her?

It has been a long time since we saw the Girl Of Steel in action, but that wait has finally come to an end. After a lengthy hiatus due to the coronavirus pandemic, 'Supergirl' returns on May 3 with a Lex Luthor centric episode, no less. We will finally learn about Lex Luthor's rise to power after the Crisis, and hopefully what are his exact plans are. He's keen on pitting Kara (Melissa Benoist) against the sinister Leviathan, as well as manipulating his sister, Lena (Katie McGrath), and making sure she is completely on his side.

The synopsis of the episode, titled 'Deux Lex Machina' reads, "Lex proceeds to lay an intricate plan to bring Lena closer to him, defeat Leviathan's latest attack and pit Supergirl against Leviathan. Meanwhile, how Lex came into power after Crisis is revealed."

This episode will be Benoist's directorial debut. Fans have been waiting for this as Benoist has expressed her desire to direct ever since Season 3. "I've been wanting to direct since Season 3, but couldn't last year because of scheduling conflicts, so (star) David Harewood did it first," Benoist said last summer. "I just felt really drawn to it for a couple of reasons now, just because you know the show so well, and you get to know the character, and the world, and the tone of the show so well that you can't help but envision certain scenes in a certain way. I want to play with that."

A lot has gone down in 'Supergirl' over the course of the season, including the multiversal Crisis, that destroyed the multiverse. Lena Luthor, who discovered the truth about Kara's identity at the end of Season 4, is still smarting at the 'betrayal' and Lex is making the best use of this anger. In the previous episode, he convinced Lena further than Kara didn't care about her and that he is the only one does. Will Lena realize the truth about Lex, or will she join him in the fight against Kara? Earlier, Kara had told Lena that she won't apologise anymore (about time) and that if Lena chooses to fight with Lex, she will treat her like another villain. 

'Supergirl' airs on Sundays at 9 pm.
