Supergirl‘s season 4 finale “The Quest for Peace” starts off 24 hours before the death of Red Daughter showing us the aftermath of Kryptoclone Supergirl coming face to face with Kara. The show jumps to the 6-hour mark where we see Lex and Eve experimenting on aliens, the hour mark where Lex meets with the president, and then the pivotal moment where find out what happened to Red Daughter. Once again the first 10 minutes of the show called SUPERGIRL is devoid of Supergirl and focusing on a male sub character, in this case, Lex Luthor.

Meanwhile, back at the ranch, after the first commercial break, we finally get to see a whole 2 minutes of Supergirl, figuring out a plan with her big sis Alex before we jump back to Lex, doing yet another experiment on Red Daughter. We then jump to Ben Lockwood who has captured the Eve clone and find out the fates of J’onn J’onzz and Dreamer in the Lex Luthor work camp for aliens. Luckily the duo runs into some of the aliens who Dreamer helped save in the last episode and they are more than willing to give them a diversion. Kara and Alex meet up with Lena and Brainiac and decide to release all the info that she and Lena collected on their overseas jaunt. While they think of what to do next, Lena is summoned to the Oval Office to meet big bro and mom for a creepy family reunion.

Lex in true supervillain form decides to monologue his evil and capitalistic plan that as his mom points out, sounds very Hitleresque. After Eve realizes that he plans to use his alien powered satellite to destroy Argo and kill Superman, she takes a stand and asks for an aside, only to discover exactly where she stands with Lex. Back at the facility Dreamer and J’onn use a fight to figure out how to take the facilities power killer down, so she can project and give her location and using breath on the window she writes the location of the facility and the team heads out to rescue them. While Lex gloating about how much smarter than everyone else that he is, ara’s story goes live and is instantly sent to everyone. When the team arrives at the island of Dr. Luthor, Brainiac discovers that Lex plans to destroy Argo with his new weapon and takes off to hack the system leaving everyone else to deal with Lockwood and his lackeys who literally come out of the woodwork (woods) to call out Supergirl because haters are gonna hate even if they don’t have a reason.

Jimmy, Alex, and Supergirl get to work taking down the Lockwood Lackies while Brainiac tries to figure out a way to take down Lex’s Argo killer. Lex takes off to see why his alien powered kill machine isn’t working leaving Eve to guard Lena and Mommy Dearest. Lena being the badass that she is easily disarmed Eve and Lex arrives raining down green fire on Supergirl, Alex and Jimmy who in the middle of a side effect fueled nose bleed.

Lex is surprised to see Supergirl still alive and the two of them have at it and when Lex thinks he has the upper hand because of his green Kryptopowered gauntlets but, thanks to Lena,  Supergirl has a suit and some slick acrobatics to protect her. Alex and Jimmy keep fighting to take down alien powred Lockwood their tag team efforts leave him down for the count. J’onn and Dreamer take out the satellites power source with the return of Brainiac who finally telling Dreamer her loves her and they manage to rescue all of the aliens, including  Red Daughter who takes a mega blast of Kryptonite to save OG Supergirl and her death allows her to suck up some of Red  Daughters superpowered chi and defeat Lex who chooses to die rather than be saved by a Kryptonian. But, he doesn’t die, he just falls to earth, back into his lab where Lena cures him of his superpowers and Lena realizing that the world will never be safe with Lex around, decides to shoot him and with Lex’s dying breath he tells him that Kara is really Supergirl and makes it appear that everyone she loves doesn’t love her back.

To wrap up the episode, the president is impeached, Dreamer and Kara are back to work at Catco with a now one-eyed Jimmy. The Alien Amnesty act is reinstated and Supergirl gets thanked for her service which brings a smile to her face. We also get the thing we had been rooting for since Jimmy’s sister showed up, her and Alex decide to give it a go and when Alex kisses her while she’s explaining how she feels and we all cheered. Lena shows up to game night with the secret on her conscience and Kara and Alex decide to wait yet another day before telling her the truth. Lockwoods son becomes a crusader for alien coexistence and Dreamer covers the story while Supergirl gives a knowing smile from the sky. In an effort to tie up all the loose ends we find out that Leviathan was pulling the strings and he’s the reason Eve was working for Lex but, now she can’t escape them.

Overall, the season finale was surprisingly good even if it was only 50% Supergirl featuring. Considering the abysmal amount of screen time that the title character got this season it was a start to heading in the right direction. The writing was pretty good, the directing was flawless, the cinematography relayed the tone of every scene perfectly and the episode was entertaining to watch. They managed to fit a lot into the hour,  wrapped every major storyline up and give us something to look forward to in season five. I hope that this return to being mostly Supergirl focused writing I saw in this episode continues in Season 5 because, while I love the other characters, I still think it should be about them in relation to her and not the other way around.

I give this episode a solid 8.9
