Major spoilers are included in this episode review. Read with caution!

I lost any hope for a comeback a few episodes back for this season and from how this finale was structured, so did the show. Instead of trying to give us a fleshed-out conclusion to the World Killer known as Reign, Supergirl decided to cut its losses and look toward the future.

Let's start with what I liked about the finale. The action scenes in the opening were amazing to watch (Kara and Alura flying around was sweet!). Saturn Girl and Brainiac 5 returned to save the day and to also deliver bad news to both Mon-El and Winn.

While Pestilence was defeated in the future, it brought back another equally dangerous threat (alluded to the original Brainiac), making it dangerous for Brainy to go back to his time. In his stead, he wants Winn to join the Legion and to help make the future safer for his kind.

Winn is conflicted about this because he would miss his friends and the guilt he carries over Dimos' death. However, Brainy shows him a glimpse of the future with an artifact (his drawing) and tells him how his protection belt is the first of many in groundbreaking technology.

This, and with James' encouraging, Winn decides to join the Legion. Mon-El also takes his leave after Reign's defeat and has an awkward goodbye with Kara. After so much buildup on the whole "Will they/Won't they?", the way they decided to choose their duty over love felt weak and rushed, especially in regards on how they ended Mon-El/Imra.

I enjoyed the J'onn/M'yrnn goodbye and how it affected J'onn to make a life-change: to leave the comforts of the DEO and to live among the humans like his father wanted for him. He takes a leave from the DEO and puts Alex in charge as the new director. This gives her the chance to do her job but also to stay out of the danger in order to start her family.

Alex and Lena shared a profound moment about knowing what they want and her desire for children vs wanting to do her job. This is an interesting friendship in my opinion because Kara/Lena/Supergirl are still on the rocks by season's end.

The whole Alura/Kara reunion was a disappointment to say the least. They rushed the precious mother/daughter time in three episodes and said their goodbyes like they wouldn't be able to see each other again. You have spaceships and holograms... I think you two could figure something out! I hope they find some way to reuse Argo City in the next season.

James got the "Superman" mention - explaining why the Man of Steel is not there helping everyone in National City - and he also outed himself as Guardian to the world. He got his Iron Man moment, which will most likely have consequences in the future.

Sam, after a journey to the Dark Valley, finally found her Kryptonian strength and used it to defeat her alter ego. However, this came at a price. Before Reign was killed, she managed to kill Sam, Alura, and Mon-El in a heat vision frenzy.

This bothered me because they tied it with the whole "I don't kill" thing. Supergirl is adamant on not killing Reign despite finding no other way. She lets everyone else reasonably convince her that killing is the only way, and it costs everyone their lives.

Unable to deal with this, Kara takes Mon-El's Legion Ring and finds a "distortion" to travel back in time. She pulls a "Barry Allen" and goes back right before Sam delivers the finishing blow to Reign. This time, Supergirl uses the black rock to take Reign back to the Dark Valley, where she is imprisoned forever.

This allows Supergirl to stop Reign without killing and to give Kara the closure she needs to accept herself as both human and kryptonian. Sam is also 100% human, which thrills both her and Ruby. They can finally move on with their lives.

We'll see if they return for the next season, but if not, they did the best they could for Sam's character, but major praise for Ruby. It's hard to incorporate children into superhero shows, but Supergirl did it and I was quite pleased.

Alura takes back the black rock to Argo City and takes comfort knowing no one on Earth has it. This is when I rolled my eyes because I SPOTTED LENA LOOKING GUILTY! She kept some of it for herself to study, which will cause major trouble for her once Supergirl figures it out.

Is Lena evil or not? Time will only tell if she will live up to the Luthor name...

Selena and her followers were also dealt with... they are being sentenced on Argo City, which gives Kara comfort because no killing is cool. Adding them into the mix felt weird and one-dimensional as we got to the season finale... like I'd rather have Purity and Pestilence around.

Coville also survived his ordeal (being the one who alerted the Superfriends on Selena's location) and will most likely return to cause trouble. I loved him as a villain and hope to see more of his cult leader stuff in the future.

But the World Killers are behind us. The show wants us to forget and move on, and we should do the same...

Winn's goodbye with everyone was incredibly emotional. His goodbye with Alex though was more heartfelt than Kara's, which is weird considering it should be the other way around. I did tear up though when Kara mentioned how this all began with her and Winn.

Winn may be gone, but Brainy will be sticking around to replace him as the "smart guy". I hope this will give the show a new outlook and maybe they can explore the Kara/Brainiac 5 romance in the next season. Or at least hint that it will happen.

I was a fan of the relationship in Justice League Unlimited.

Now let's talk about Kara's "big time travel mistake". She created another version of herself who popped up in Siberia!! Wow time traveling in the Arrowverse always has consequences. I think it was also a combination of the black rock splitting her too.

I'm looking forward to seeing how this will play out.

The finale resolved the season's big bad in the first half and spent the second half playing "set-up" for the next season. I thought that was an interesting approach and a good indicator on how the show realized how off-the-rails they got toward the end there.

This will be the last Supergirl episode review of the summer, but rest assured, I will return in the fall to review season four! ON SUNDAY NIGHTS! YAY?
