(Wonder Woman is about to slit Harley Quinn's throat when Supergirl simply attacked her, much for the heroes's surprised)

Wonder Woman: (enraged) Kara, you idiot! Who do you think you just attacked?

Supergirl: An idiot? Yes... I was an idiot to not realize your true intentions, Diana!

Wonder Woman: Kara...

Supergirl: You were supposed to be fighting to honor the amazons' purposes!

Wonder Woman: The very ones who exiled me? The time I spent exiled taught me one thing. There is only honor in victory!

Supergirl: You really forgot the true meaning of honor, huh?

(Kara got completely angered by seeing what Wonder Woman has become. Then she shows her true power and defeats the one she used to trust)

Supergirl: I trusted you, Diana...

(Shazam comes in)

Shazam: I trusted your cousin too, Kara. But when he decided to destroy major cities and invade worlds in other dimensions, my trust on his actions have decreased at the point I couldn't be loyal to him anymore.

Lex Luthor: The peace he claims to be trying to bring...is a joke.

(Then Colonel and Hiro come in)

Colonel: Just like Billy, Barry and Hal, I was blinded too... His promises to help the Repliforce to achieve its independence were simply empty.

Hiro: He tried to kill me, but my brother Tadashi saved me. In retaliation, he sent Callaghan to kill him.

Supergirl: And all of this because I wasn't there when he needed.

Shazam: Not exactly, Kara. Your cousin did all of this because The Joker drugged him...made him kill his wife...and their unborn son.

Lex Luthor: And caused the destruction of Metropolis.

Supergirl: I need to talk with him!

Grim: I'm going with you!

Oscar: Me too!

Ariel: I'm going to help you.

(Then Layer communicates with Marino)

Layer: Marino. Where is Superman?

Marino: He is at the Fortress of Solitude, alongside Nightwing and Black Adam.

Layer: A team is on the way.

(At the Fortress of Solitude)

Nightwing: Not a single weak point? That's not possible.

(Then Supergirl and her team comes in alongside Marino)

Supergirl: Kal!

(Superman sees Kara, then gets enraged by seeing Shazam)

Superman: TRAITOR!!

(Superman tries to attack Shazam, only to be blocked by Supergirl)

Supergirl: It looks like they were right after all. You changed. You're not the one they once admired. All because of a clown...

Superman: I took one life to save millions!

Supergirl: You took more than one! How many? How many, Kal?

Superman: These people are driven by their primitive instincts! They must be protected from themselves!

Supergirl: You were supposed to be Jor-El's son. But you are more like the son of General Zod!

(Then Nightwing confronts Oscar)

Nightwing: Seriously, who are you?

Oscar: I'm Oscar Pines, the newest member of the Neo Beacon.

Nightwing: The very group which helped Batman to put me in jail and make me suffer?

Oscar: You must really hate him, huh?

Nightwing: I really hate Batman! And I hate the fact I'm his son even more! Superman was more of a father than he ever was!

(Knowing there is no reasoning with Nightwing, Oscar fights him. Thanks to Ozpin's teachings, Oscar manages to defeat Nightwing)

Oscar: So much for ungratefulness.

(Shazam faces Black Adam)

Shazam: To think another child got corrupted by your evil...

Black Adam: A child? That's true... Kara sees the world as a child. There is no good or evil. Only power!

(Shazam fights his longtime archenemy. He goes all out and defeats Black Adam.)

Shazam: I can see where Superman took such vision from.

(Back to Superman and Supergirl)

Superman: Think about what you lost!

Supergirl: You think I don't remember? The house of El has a purpose. To inspire hope.

Superman: Hope isn't enough to save the world!

Supergirl: And you think fear is? Maybe they were right about you after all!

(Superman refuses to listen to his cousin and simply wants to hurt her. Knowing that her cousin is long gone, she decides to use her full power and defeats her own cousin)

Supergirl: I will not lose my hopes.

(Then Ozpina communicates with Oscar)

Ozpina: Oscar. We need you and your team in Vale immediately!

Oscar: Understood. (to his team) Brainiac is attacking Vale! We need to help them.

Supergirl: Count me in, Oscar.

Oscar: I knew I could count on you, Kara.

(Then Superman gets up)

Superman: (to Supergirl) After I'm done with Brainiac, you decide if you're either in my side, or against me!

(Then he files away)

(In Vale, Team RWBY, Kevin Rose, Batman, Ben 10, Axl, and other heroes try their best to break through Brainiac's force field)

Kevin: Time for my last resort.

(Kevin Becomes Ultra Instinct Sonic)

Kevin: Time to blast through with sonic speed!

(Kevin tries to break through Brainiac's force field again. As he was about to break through, Superman comes in and puts everything at stake as he recklessly tries to destroy Brainiac's ship. Then some black hole appears and takes Kevin as Brainiac's tendrils hit Superman rendering unconscious and the ship desintegrates him, seemingly killing him)

Ruby/Yang: BROOTHEEER!!

Weiss: Oh no... KEEEVIIIN!

(Blake falls into tears as Kara does the same thing)

Blake: We are doomed...

Supergirl: I'm sorry for your boyfriend, Blake...

Weiss: Sorry? Do you know what your dunce cousin just did? This is all his fault!!

Supergirl: Kal was trying to help! I know I was blind about my cousin!

(Wonder Woman comes in)

Wonder Woman: If you want to blame somebody, blame Bruce! (points at Batman) If HE followed OUR lead, we could have finished Brainiac!

X: (to himself) Darn...

(Then Brainiac and Salem's mugshots appear)

Brainiac: You don't have much time to save your planet, Neo Beacon. But I have a proposition you can't refuse. Give me Kara, and your planet will be spared.

Salem: (to Ozpin) Yeah, Ozpin. It looks like you lose.

Ozpin: (growls) Salem...

(Then the mugshots disappear)

Supergirl: Thanks for giving me a chance. But I failed you.

Shazam: No. There is still a chance. (to Aquaman) If your trident is channelled with the rock of knowledge, we can possibly destroy Brainiac's force field.

(Then the heroes nod in agreement)

(Kevin Rose got captured. But our heroes got a Plan B. Will they manage to rescue their friends and Kevin? Stay tuned for more)
