After a tense and dramatic run, CW's 'Supergirl' wrapped its third season with an epic showdown, leaving fans with a huge cliffhanger. In an attempt to stop Reign (played by Odette Annable), Selena (Anjali Jay) and the rest from taking over Earth, the final episode that aired on Monday, 18 June - titled 'Battles Lost and Won' - featured a face-off with Kara Danvers and co. traveling through time and making some irreversible changes. 

A fitting finale that not only set the stage for newer things and plotline in season 4 but also paid an apt homage to the iconic Red Son arc. 

Here are top three moments from Monday night's finale that left fans awestruck and wanting for more Girl of Steel action. Spoiler alert: If you are yet to catch up with season 3 episode 23, it's the right time to avert your eyes. 

1. The introduction to a second Kara 

During the battle with Reign, Supergirl, in order to save Sam, had to do some time traveling. She went back in time, and stopped the unfortunate from happening, in the process putting Reign to sleep forever. To accomplish all this, Kara had to use Harunel - an action that seemed to have some serious implications as reflected in the last scenes, when a second Kara is born out of Supergirl's aura in Siberia. 

Explaining the scene, executive producers Robert Rovner said, "Fans of the comics, I think they might recognize that the story we want to tell is inspired by the iconic DC Comics’ Red Son, which told an alternate origin story for Superman."

“What happened if — as a baby — Superman landed in Russia and became a hero there instead of in America. It’s an homage to that.” added co-executive producer Jessica Queller.   

2. Goodbye Winn and hello Brainiac-5

In the final episode of season 3, Winn Schott took leave to join the Legion of Superheroes in the future. The fact that actor Jeremy Jordan, who has been bringing Winn to life since the very first season, too has been listed for a recurring than a regular role in the upcoming season is a clear sign that Supergirl is preparing to say goodbye to the character for a while. 

But the good news is there will be more of Brainiac-5, a role played by Jesse Rath - who has been upgraded to series regular. 

"We love the character of Brainiac-5 and can't imagine anyone but Jesse Rath in the role," Rovner and Queller told Deadline. "He brings such fun, heart and brilliance to Brainy and we're so excited he's joining the cast as a series regular for season 4. We have a lot of great Brainy stories to tell."

3. A tragedy for J'onn

The sacrifice that M'yrnn took upon himself will undoubtedly have ramifications in the future course of events, especially for his son J'onn, who even steps down from the position of DEO to return to Mars. 

However, before his passing, J'onn's father transferred a critical bit of memory to him - the knowledge about the Sacred Scrolls. As J'onn (David Harewood) begins a new journey with his father's memory, fans can expect more grounded storylines for him in the future.  

After the temporary exit of Winn and more permanent departure of Mon-El (played by Chris Wood) in the recently-wrapped season of Supergirl, one thing is certain - there is going to be some major shake-up as far as the setting and plot of the fourth season is concerned. One thing that fans should watch out for is more Legionnaires, especially with Winn joining them in the future and Kara getting her own Legion ring from Mon-El.
