We've only done this two other times and each time we think a finale can't be topped. We were proven wrong yet again because the season three finale of Supergirl was simply incredible! The entire fate of the world was held in the balance. To show our bias just a little, on The Flash, all of humanity on Earth 1 was threatened by the Thinker, but tonight, our entire planet could have been lost. That's not just humanity, but all life! This was a challenge that only Supergirl and her team could stand up to! Despite the magnitude of the situation, there were plenty of touching personal moments that seemingly held just as much magnitude. Breaking it all down isn't easy but here is what stood out to us:

1. The Terraforming of Earth Has Begun: As we saw at the end of the last episode, the fate of the planet was at stake as the Earth was beginning to terraform into Krypton via Reign's sword and power! A multitude of catastrophes ensued where the first 10 minutes or so was pure action! James, as Guardian, had to stop an irrational mother from going into a burning building by revealing who he was so she would trust him to get her son. A tsunami also was heading to National City where Supergirl and Alura were able to freeze it with the help of the Legion who had just returned. Imra held the water in place while it was frozen and Brainy blew it apart.
2. M'yrnn's Goodbye: There was little time for J'onn and M'yrnn to say goodbye as he needed to meld with the planet to stop the Earth from terraforming. He shared the quickest memory with his son before he had to go. It was the birth of the Martian religion and their people. J'onn says he's not ready, who is when a parent dies, but M'yrnn says J'onn will never be alone and phases into Earth.
3. The Future Threat: When Pestilence was destroyed, history was changed. Because of this, Brainiac (the original) survived and is now attacking all future artificial intelligence. Now, Brainy must stay in our time so that he won't be killed. Further, we learn that Winn's invention of the circuit that he used to make the force-field ended up being a catalyst technology that the future uses everywhere. Because of this, Winn is asked to go to the future in Brainy's place to help the Legion! On top of all of that, Imra and Mon-El break up but the looming threat on Brainiac in the future means that Mon-El is needed there to lead the Legion more than ever!
4. The Dark Forest: Sam was shocked into the Dark Forest again last episode so that she could find a spring fountain that would give her human side strength. She was guided and helped by Patricia's spirit. At first we weren't sure if she was to be trusted, but after singing Sam a lullaby, Sam was able to ingest enough of the strength giving water to give her powers that match any Kryptonian! She awakens in the DEO where Lena and Alex tell her where Reign and the team are. Sam flies out of the DEO with her new power!
5. The Forest is The Prison: In pretty true fashion for comic book, we diverted down a what-if, what-could happen moment. Sam flies in and stabs Reign then Kara goes against her better judgement and knocks Reign into the fire pit that kills her but her rage isn't contained and she kills Mon-El and Alura with heat vision before she dies. This triggers Supergirl to have a sort of epiphany where she knows that she was wrong to kill. Taking Mon-El's ring and having Winn find a time disturbance like the one from the season 2 finale, Kara flies into space where she travels back in time to stop Sam and herself from killing Reign. The Dark Forest is actually a prison that can hold Reign and with both Supergirl and Sam in the forest with Reign, Sam is able to force Reign to drink from the poisoned part of the fountain spring giving all the power back to Sam and trapping Reign in the forest indefinitely. This of course undoes any deaths that happened before.
6. Mon-El Heads To The Future: The Brainiac threat is too big to ignore and it would diminish who Mon-El has become to stay in the current time with Kara. Kara knows this and with a tearful goodbye they part, but not before Mon-El gifts Supergirl a Legion Ring of own! She can now call on the Legion to come and help if she needs it! Not to mention the new powers the Legion Ring gives her with the ability to fly in space. Winn will travel with Mon-El to the future and they will work together to defeat Brainiac!
7. J'onn and Alex: Alex is ready to make a change to chase her dream of becoming a mother. She gives J'onn her notice that she is leaving the D.E.O. so she doesn't have to put her life on the line all the time. In a twist, however, J'onn realizes that after his time with his dad that the Martian way is to live among the people. He actually promotes Alex to director of the D.E.O. which will reduce her time in the field and allow her to chase her dream of having a family. J'onn, however, vows not to leave Alex as they are family and he will be there for her whenever she needs him.

Final wrap up moments. The show ends perfectly with Alex and Kara on the couch. They talk about everything new, all the changes, the choice that Kara made to remain on Earth and not go to Argo.  Then Alex asks, "Are we going to be ok"? Not so much about the two of them but more in a way of what is to come. Kara takes a moment and answers, "Yes". Furthermore, James is contacted by the media for a quote that someone is saying he is The Guardian. He replies, "I am the Guardian" and his secret is out! The big cliffhanger, however, is that it would seem (and like all good cliffhangers, we aren't sure) that the choice Kara makes to travel back in time and redo the fight with Reign has caused a split in time. A second Kara comes walking through the snow in Siberia barely clothed in rags and approaches what looks like a military installation. Could the grief of killing Reign have caused this version of Kara to go mad? Is it even the same version of Kara or is this somehow a clone like Bizarro was? So many questions ahead!
