Kara was able to escape from her captors with ease and was on her way out when she came face to face with Red Daughter...and she had kryptonite.

"I'm supposed to kill you, you know." Red tells Kara while holding a gun.

"I see that." Kara says as her hands are tied with kryptonite in her hands and she can't let it go since it's tied with chains. "Kryptonite makes me soft. I bleed, you shoot me. I went to Kaznia. Saw those pictures you have of me, my sister, and my boyfriend."

"Know thy enemy." Red says.

"Please don't do this." Kara begs of her. "We are the same. We have the same genes, the same-"

Red groans in annoyance. "I see we've come to the part where the villain says we are not so different, you and I."

"I am not a villain." Kara tells her.

"The devil can cite scripture for his purpose." Red says.

"Lex Luther sent you here, right?" Kara asks. "So once you've done his bidding, what's he gonna do to you? You're a lose end. Everything he's told you, he's lying. He hurts people. For gods sake, just look him up."

"He did those things in service to the world." Red says and stands up. "You are so limited. Your life could mean so much, and yet you fly around in a cheerleader skirt."

"Yeah, my boyfriend kinda agrees on that last point." Kara admits, since it's because of that skirt that Peter calls her Skirt.

"How did they do it? What did they say to make you believe?" Red asks Kara. "Look out the window and you will see fear, racism, strife. This country is a ragged heifer. I am here to cut its throat. But first...admit that you were wrong. Go on. That you defend the corrupt. The American Dream is snake oil." She says as she starts getting affected by the kryptonite as well. "Who sold it to you? Was it your Alex?"

"You know, for saying that you want to know your enemy, you don't know me at all. For instance, I am known for stalling." Kara says, now happy Peter hid a tracker on her person. Only for this case.

They hear a knock come from the door and are confused.

"Room service." They hear Peter's voice when he blasts the doors and leaps into the room, sending Red Daughter flying into the bedroom.

"Took you long enough." Kara tells her boyfriend.

"What, did I not fly halfway across the country fast enough for you?" Peter asks as he rips the kryptonite out of her hands and carries her out the window before taking off, leaving Red Daughter.

"I almost had him!" Kara complains now that all of her evidence is gone thanks to the president now they're at J'onn's private eye place. "And now I've got nothing. Lockwood walked, and people think Supergirl's an assassin, and the President is working with a man who's almost blown up the world more than once."

"Five times to be exact." Peter tries joking and sees that didn't help. "Sorry. I've been hanging with my doppelgänger too much. Look, don't do this to yourself."

"I've been telling myself...the pen's mightier. Do what ms. Grant would do. And it all fell apart." Kara tells him.

"Listen, we will solve this." Peter promises and takes her hands. "Together."

"Lex knows who we are. He's been following us. He wants us dead. Which means everyone we know is in danger." Kara informs him.

"They will be safe." Peter promises, moving some loose hair of hers behind her ear. "Everyone we know can take care of themselves. Besides, what's Lex gonna do? Kill the director of the DEO on the downlow? Kill James after already failing to kill James?"

Kara understands and sees he does have some valid points.

-

Lena went to confront Lockwood where she learns that he knew nothing about Lex and informed him now he doomed the world.

J'onn, Brainy, and the Dream Team are working on locating where all the aliens are being taken to and found a shell company of Lex's.

AmerTeck.

They tried to sneak in, but that ended with Dreamer and Brainy getting captured.

J'onn was able to sneak Morg'Ann and Gwenyth in where they found a portal and they watch the aliens being forced through it.

"Where does that lead?" Morg'Ann questions.

"Some place worse than here." Gwenyth guesses.

"You two see if you can find out where it leads, I will find Brainy and Dreamer." J'onn tells them and they begin to split up.

Unknown to them, Brainy just went through torture and has rebooted to be like his other Braniac family.

-

Kara and Peter went to the DEO to find a way to track Red Daughter which Alex was able to do using Kara's signature.

"Red Daughter's been busy." Kara comments looking at the locations her lookalike has been.

"Project Claymore. Remember that?" Alex asks.

"Yeah." The heroes reply.

"I went to D.C. and asked around. The blast that Claymore was powered by was an unknown energy source. Six engineers involved in R and D, and when I tried to find them, they were all killed in these locations." Alex explains.

"Luther wants the Claymore technology." Peter guesses.

"We need to find and stop him, but we need to find Red Daughter first." Kara says and they try to find a location they all intercept and get a place in National City. "Let's go." She tells Peter and they head out.

-

The two of them make it to the location and look around to find a apartment eerily similar to Kara's.

"Does this place look familiar?" Peter asks as the place looks exactly like her place.

"I've got a completely crazy stalker." Kara replies.

-

"They're draining alien power and converting it to kinetic energy for use in what looks like a version of the Claymore particle weapon." Brainy informs J'onn. "Yet there does not appear to be any extraction equipment on premises."

"We found a transmatter portal." J'onn says.

"They must be transporting them to a second location to drain their power." Brainy guesses. "We must find and disable it."

"But what about Dreamer? I have the girls trying to see if they can find anything to where it leads." J'onn says.

"Yes. She could be useful. I believe I know where they took her." Brainy says and J'onn's getting concerned.

"You feeling okay?" J'onn asks.

"I am not experiencing any pain." Brainy says as he walks off.

-

Kara and Peter look through Red Daughter's apartment for anything to lead them to Lex and all Kara found is a photo of a young boy in her diary when Alex joined them.

"Alex, what are you doing here?" Kara asks.

"I told you, you're not doing this alone." Alex says and looks around. "Why does this look like your place?" She asks as she looks out the window. "I can see your loft from here."

Alex's phone just went off and she answers it.

"Mom, is everything okay?" Alex asks.

"Oh, yes, just wanted to let you know that Kara just got here." Eliza says and everyone looks to Kara. "She wanted to call so you knew she was safe."

Kara speeds off quickly and Peter leaps out the window to fly after her.

-

Kara made it there and sees Red Daughter's holding her mother hostage.

"Dot hurt her. Please." Kara pleads.

"I've been here for hours. You have all these...things. You think they will make you whole? I had none if it." Red Daughter tells her.

"You can still have it." Kara tells her.

"I don't want it." Red replies.

"Then why do you have an apartment in the city? I know you have doubts about Lex." Kara says.

"His name is Alex!" Red says, tightening her grip on her mother's back.

"Okay, easy." Kara says raising her arms.

"You protect individuals. That is weakness. I serve the collective."

"What about Mikhail?" Kara asks, referring to the boy's photo she found. "I know he's important to you."

"Interesting that you should bring Mikhail up. Americans killed him." Red Daughter says when she gets blasted from the back and Kara sees Peter finally made it.

"This place is really hard to find." Peter comments when Red Daughter gets back up and a suit forms around her that looks like Lex's suit Peter fought the other day, except it's domplet dark blue.

"Oh boy." They both say, knowing this is gonna be rough.

They fight through the forest as they fly through the house.

Peter webs and pulls her at them and Kara punches Red Daughter.

"Hope, help, and compassion for all." Kara says. "That's what we stand for."

"Neither of you will be able to stand for long when I'm done with you." Red Daughter promises.

"You sound strange with an Russian accent." Peter tells Kara as this was the first time he's hearing her speak as they run at Red Daughter only for her to punch Peter sending him flying.

"How do you think this ends?" Kara asks. "We have the same powers."

"Not exactly. I am evolved." Red Daughter says and charges up a purple blast charged from Harun-El to hit Kara, but Peter pushes her out of the way at the last second and he gets hit by the blast.

The blast sent him flying through the forest and Kara flew up to see if he even survived that blast and sees his suit ruptured, his shield cracked and watches his hands and head glow purple like the blast.

Red Daughter flies down near the destruction and now Kara is fueled with anger.

"Submit." Red tells her.

Kara gets up and faces her. "Not while I'm still breathing." She states through her teeth with anger in every word.

The two then get back into fighting and Kara keeps her away from the unconscious Peter when she's punched by the blast Peter took and she absorbed most of it.

Red takes her down and gets ready to finish her off when Alex comes and tries to figh her off.

Peter feels something changing inside of him and hears Alex cry out to him and hears something happened to Kara.

Red sees her work is done and flies off.

Getting his strength back, Peter opens his eyes, but they're glowing light purple as lightning sparks off of him and he raises back up to see Alex clutching a dying Kara.

Looking around, Peter raises his hand and feels his energy flowing as the sunlight is getting drained from the surrounding plants and even himself to help recharge Kara, knowing she needs sunlight to heal.

"Alex...move." Peter asks do her and Alex just notices him and is shocked when she sees he's holding a miniature sun in his hands and his eyes are glowing purple.

Peter walks over to Kara and kneels down before placing the sun to her chest, allowing her to absorb the sunlight and her wounds begun to heal themselves and she wakes up to see Peter standing over her.

"I know this is gonna be a strange question, Peter...but are you glowing...purple?" Kara asks him.

"Protect those in need." Peter reminds her what he stands for and helps her get up and his body returns to normal. "Think I learned the full strength of Super-Spider." He remembers what Gwen named him when he goes Super like that.

But now he knows he doesn't have anything like Kara or Clark does. But glowing purple and able to heal people is pretty cool, and that's only the low point of his powers. It seems the key to unlock his powers permanently was Harun-El all along. And when Red Daughter hit him with the Harun-El blast, his body absorbed it.

-

The team learned the Claymore project was made and that's what Lex has been using to power his own suit. That's why he's kidnapping the aliens. Why he needed Lockwood.

They turned on the tv later saw that the President is cheering Lex as he shows the footage of the fight and the Red Daughter dead in Lex's arms and the Kaznia's already thwarted by Lex himself.
