- J'onn J'onzz: Alex, I, uh, hope we're not disturbing you.
- Alex Danvers: No. No, no, no. There's always time for my two favorite people.
- M'yrnn J'onzz: I came because I wished to see you again, Alex. To say goodbye.
- J'onn J'onzz: [Alex glances at him] It's, uh... it's time.
- M'yrnn J'onzz: You have brought me much joy in my time on your Earth, Alex. You and your friends showed me strange and wonderful things. You know, you have a rare gift for intuiting the feelings of others. You would've made an excellent Green Martian.
- [Alex starts to cry]
- M'yrnn J'onzz: Most of all, you have given me the great gift of witnessing your love for my son. Home is not a place. It is living among those who love and honor you. I can depart this world with peace because I know my son is home.
- Alex Danvers: It has been a great honor getting to spend time with you, M'yrnn. And now I know where J'onn gets his dignity and his enormous heart.
- M'yrnn J'onzz: There is no need for watering of the eyes, child. All of life is change. Doing the Reach allows me to live on forever, within my son. I am very, very fortunate.
- Kara Danvers: Father's lab. I can't believe it's still here. I spent so many afternoons with him here, watching him work. Sometimes when he was working on a problem, he'd use me as a sounding board. He talked to me like I was another scientist. He'd make me feel like the most important person that ever existed.
- Alura Zor-El: Winn, listen to me. I am using cache crystals on Argo City to reach you. It is the only way we have of communicating from under the dome. I know I sound like Alura.
- Kara Danvers: [cut to Argo] But it's Kara. My mom and Mon-El are with me.
- Alura Zor-El: [cut back to the DEO] We're stranded on Argo. Sam's in trouble, and we believe that Reign is still alive.
- Winn Schott: ALEX!
- Alex Danvers: Kara, is that really you?
- Alura Zor-El: Yes. Alex, this is an emergency.
- Winn Schott: No, I feel like we need to give her a test or something. Like... like, uh, like something only Kara would know. Right? Like, what was the name of your first pet?
- Alura Zor-El: Streaky!
- Winn Schott: No, no. That's too easy. Everybody knows that.
- Alura Zor-El: [impatiently] Alex?
- Alex Danvers: Winn, shut up.
- M'yrnn J'onzz: The process will begin with my most recent memories, and travel back through my life, and then the lives of all those I am connected to. It will be painful at times as we venture back through my imprisonment. But we will break through those barriers, and you will touch the parchment of the sacred scrolls, breathe the air on Mars, moments after its creation.
- J'onn J'onzz: I am ready to face it all.
- M'yrnn J'onzz: I never imagined that my memories, the history of our people and our religion, would live on when I passed. And now, all of it will in you. Let us begin.
- Alura Zor-El: [watching Mon-El work] He's a good man.
- Kara Danvers: Yeah. Yeah, he is.
- Alura Zor-El: The connection between you two is obvious. He makes you happy. Do you love him?
- Kara Danvers: Mom, that's... that's not an easy question to answer.
- Alura Zor-El: Why not?
- Kara Danvers: There's a history between us. And complications.
- Alura Zor-El: When this crisis is over, I hope that we will find time for you to tell me all about it.
- Kara Danvers: I'd like that.
- Supergirl: Mom, this is Alex.
- Alura Zor-El: [hugging her] Oh!
- Alex Danvers: I...
- Alura Zor-El: You and your family rescued my daughter. I am indebted to you.
- Alex Danvers: Well, sometimes I think she's the one that rescued us.
- Winn Schott: Yo, Demos, punch me.
- [Demos turns to stare at him]
- Winn Schott: You heard me. Punch me.
- Demos: [standing up] Finally.
- Winn Schott: Seriously? You're not even gonna, like, ask...
- [Demos throws a punch, but his fist is deflected upon contact]
- Winn Schott: [doing a taunting jig] Eh? Huh? Eh?
- Demos: You know, that wasn't as satisfying as I'd imagined. And I've imagined it.
- Demos: What happened?
- Winn Schott: An omnidirectional, self-maintaining, subatomic personal shield. Boom.
- Demos: Cool. How does it work?
- Winn Schott: Oh. You know what, here. Check it.
- [he draws a diagram in a notebook]
- Demos: That literally looks like nothing.
- Winn Schott: Dude, it's a frequency conversion capa... you know, don't worry about it. It's all good. Point is I invented it, and it's, like, the cornerstone of all the non-lethal tech that I'm creating for J'onn. Oh, it's like, uh... like a magnet for atoms.
- Demos: [high-fiving] You're a genius.
- Winn Schott: Yeah, change the world, that's what I do. Oh! Check it.
- [he tosses Demos his own shield buckle]
- Winn Schott: [ripping the page out of the notebook] And you know what? This is top secret research.
- Alex Danvers: Okay, tell me what's going on.
- Alura Zor-El: Dark Kryptonians stole our ship and flew to Earth. It turns out the Harun-El we used to kill Reign and save Sam split them apart. But Reign is only dormant, not gone. The Dark Kryptonian witches want to resurrect her and use her to terraform the Earth, turning it into a new Krypton.
- Alex Danvers: Okay, tell me you have a plan.
- Alura Zor-El: Mon-El and I need to get back to Earth. Father has a transmat portal, but we need to make it work.
- Winn Schott: Transmat portal? Okay, I can help you set yours up, then we will get ours working, and then we can interface them, yes. And you are, Kara, right?
- Alex Danvers, Alura Zor-El: Yes!
- Winn Schott: I knew that. I knew that.
- Winn Schott: Okay. So, we should really be able to talk now.
- Mon-El: Yeah, I just need a few minutes to route the power from Argo's main grid.
- Winn Schott: Okay, do you see a multi-phase descrambler which links to a power source?
- Mon-El: Uh... yeah. Yeah, but the insulator is cracked. Which means as soon as we go through the portal, the circuits will fry, which makes it a one-way trip.
- Winn Schott: Well, hey, I mean, at least you don't really have any need to go back to Argo City. In fact, I'm surprised that you're still there. I thought you were gonna call the Legion and go straight back to the future.
- Mon-El: Uh... yeah. Yeah, I was. But then, uh, the time beacon broke, and Kara ran into some trouble, so I, uh, I decided to stay back to...
- Winn Schott: Mm-hmm. Always the hero.
- Mon-El: Yeah. I lost her once, Winn. I'm not sure I can do it again.
- Supergirl: [Demos is hit by three heat vision rays] No!
- Winn Schott: No!
- Vita: She actually cares for these humans.
- Selena: One would have thought that the Girl of Steel would know that caring makes you weak. Give me the blood.
- Supergirl: You want the blood?
- [she glances at Alura, who gives a small nod]
- Supergirl: You can have it.
- [she tosses then vials into the air and fires her heat vision at them]
- J'onn J'onzz: This is... this is like re-living this horror. Perhaps we should take a break, Father.
- M'yrnn J'onzz: No. The hardships we travailed are important. As we reach through them, you will learn the lessons I have learned. Be able to teach others to take a different path. And when we reach past the painful memories, inevitably, we find the good.
- Alex Danvers: If they're regular Kryptonians, we should be able to track them down.
- Alura Zor-El: They're protected by magic.
- Winn Schott: I will find them.
- Supergirl: Do you think we should call J'onn?
- Alex Danvers: No, he's with M'yrnn. I'll get him if the situation becomes dire.
- James Olsen: How you doing, man?
- Winn Schott: He trusted me. And I killed him.
- James Olsen: Kara told me that Demos got hit by three heat vision blasts at once. Nobody could have predicted that.
- Winn Schott: You know, for just a second, you-you really... really had me believing that I could change the world.
- James Olsen: Winn, just stop, okay? Look, a lot of people would have died today if it wasn't for your technology. I mean, I-I would've died a hundred times over if it wasn't for you.
- Winn Schott: Alex said that you were gonna go see the mayor? Get CatCo to put out the word that the city needs to stay safe.
- James Olsen: Yeah, but I came to see about you first.
- Alex Danvers: Ruby, I really think that you need to wait outside.
- Ruby Arias: No, I'm staying.
- Samantha Arias: Listen to me, baby. This is gonna hurt. And it's gonna look scary. But your mom is a badass. She can handle it, okay?
- Winn Schott: 8.0 earthquake, tornadoes and superstorms over Madagascar? Tsunami warning? We got a hundred percent chance of, you guessed it, Reign.
- Supergirl: It's the terraforming.
- Mon-El: On Zune, they terraformed her planet's natural resources, so they'd go right throught the planet's core to create a genesis event.
- Supergirl: Destroy all life in order to be reborn.
- Mon-El: Exactly.
- Alex Danvers: Go through the Earth's core, and you get pretty close to Madagascar.
- Winn Schott: Okay, well, so that's what the witches are doing. Can I ask how long it took this genesis event to be completed?
- Mon-El: Hours.
- J'onn J'onzz: [entering] I'm not gonna let that happen.
- Alex Danvers: The memories?
- M'yrnn J'onzz: This was too important.
- J'onn J'onzz: Supergirl, Mon-El, damage control. Alex, get every agent we have. Boots on the ground, evacuating. Winn, I want you to monitor everything from here. I'm gonna find out where this is coming from and stop it.
- M'yrnn J'onzz: Wait. Take me to the nexus point. If I shapeshift into the Earth, bond with it, I can stop this.
- J'onn J'onzz: It'd rip you apart.
- M'yrnn J'onzz: This planet is my son's home. I intend to save it with him.
- Alura Zor-El: [in Selena's house] It's an atlas of the Earth.
- Kara Danvers: I've seen these writings before, in Coville's journal. They're instructions.
- Thara Ak-Var: Instructions for what?
- Mon-El: For making Worldkillers.
- Kara Danvers: Seems the Daughters of Juru created Reign, Purity, and Pestilence years ago on Krypton and then sent them to Earth. And now, they're following.
- Mon-El: We have to find a way to let the DEO know that Selena's headed back to Earth.
- Thara Ak-Var: Our protective dome makes communication impossible.
- Mon-El: There has to be something here that can help us.
- Samantha Arias: What time is it? Is it morning?
- Ruby Arias: Something's wrong. You're sick. Please don't tell me you're fine. Not again.
- Samantha Arias: You're right, I don't... I don't feel well. And you're also right, I should've been honest with you from the very beginning. That was a mistake. But here's the truth. I don't know what's going on with me. But we're gonna call Lena and Alex, and they're gonna get to the bottom of this, okay?
- [Ruby nods half-heartedly]
- Samantha Arias: Okay?
- Ruby Arias: Okay.
- Samantha Arias: Hey. I love you more than *anything* in this world. I promise you I will never keep in the dark again.
- Alex Danvers: Is there anything I can do? I-I can come with you.
- J'onn J'onzz: This is something I have to do on my own. But knowing that you're there is help enough.
- Thara Ak-Var: Kara, do you recognize this?
- Kara Danvers: [reading an inscription] "Whoever wields this sword shall bathe in the blood of the old worlds, and reign with might over the new."
- Alura Zor-El: It's an ancient religious text. According to lore, the scabbard holds the sword of Juru.
- Mon-El: It would appear the sword is real, and missing.
- Alura Zor-El: Kara, look.
- Kara Danvers: Is that a hologram crystal?
- Alura Zor-El: Yes.
- [she activates it, and a hologram of Selena appears]
- Selena: Hello, Alura. I'm sorry I couldn't say goodbye. I was in a rush.
- Alura Zor-El: You may have left Argo, but you will never be able to escape yourself, Selena. Your shame will follow you on any planet.
- Selena: It is you who should feel shame. You, who are responsible for the death of Krypton, you who are unrepentant.
- Alura Zor-El: I lost my home, just as you did. I lost my husband. I thought you and I had been rebuilding our culture together.
- Selena: Our culture? For twenty years, I've been biting my tongue, masquerading as one of you, while my culture has been forced into the shadows, deemed unworthy.
- Kara Danvers: Then why did you give us the Harun-El?
- Selena: My sisters and I have waited patiently for the Worldkiller to rise and make the Earth habitable for our people. It was supposed to happen long ago, but the human in Reign proved strong. Reign and Samantha Arias had to be separated. I was going to do it myself, but you saved me the trouble. Only one of them will survive the split. How quaint that you thought it should be the human.
- Kara Danvers: Sam is alive and Reign is dead. I saw it happen.
- Selena: You're naïve, just like your mother if you thought that is what happened.
- Mon-El: And you're naïve if you think the people of Earth won't find a way to stop Reign.
- Selena: Oh, it's not Reign who will need to be stopped, it's Earth herself.
- Kara Danvers: What do you mean?
- Selena: Reign is the spark that ignites the eruptions. Seismic catastrophes that would wipe out all humans and terraform the Earth. It's almost a pit, really, that you won't be around to see it.
- Kara Danvers: [realizing just in time] We have to get out of here. It's a trap!
- Samantha Arias: I was better, Alex. I was me. Now I feel like I can barely hold my head up.
- Alex Danvers: What about the blackouts? Are you still losing any time?
- Samantha Arias: I just feel like my insides are wilting away.
- Lena Luthor: Sam, your blood cells have mutated. Before, they presented as human. But now, they are transforming back into their natural state, which is Kryptonian.
- Ruby Arias: Like Supergirl? Isn't that good?
- Samantha Arias: No, I don't feel stronger. I've never felt weaker.
- Lena Luthor: That's because your blood cells are oxygen-deprived. They're shrinking. In fact, they look like they're becoming dormant.
- Samantha Arias: We need to fix this. I have not fought this hard to lose now.
- Lena Luthor, Alex Danvers: We will.
- Ruby Arias: If she's Kryptonian like Supergirl, can't you fix her with the sun?
- Alex Danvers: Yellow sun lamps.
- [a thought strikes her]
- Alex Danvers: She's right.
- Lena Luthor: The sun lamps should heal you.
- Alex Danvers: We're gonna supercharge you.
- M'yrnn J'onzz: I am ready, my son.
- J'onn J'onzz: There's so much I want to say to you. But I'm afraid that once we start, I won't get a chance to finish it all.
- M'yrnn J'onzz: No. Our thoughts, our words will flow freely as we begin the Reach.
- [J'onn removes his psychic dampener]
- M'yrnn J'onzz: My mind is free again.
- Kara Danvers: Selena couldn't have known I was going to come back after she gave me the Harun-El. She had to have another plan to get to Earth. Are there any other ships on Argo?
- Alura Zor-El: No, they were all destroyed, and we've rebuilt nothing.
- Kara Danvers: What about the Legion? Can you call them with the beacon?
- Mon-El: Unfortunately, the beacon didn't survive the explosion.
- Alura Zor-El: All your father wanted to do was save us all.
- Kara Danvers: Well, he built this dome. He saved Argo.
- Alura Zor-El: He was looking for another way, but he never got it completed in time. Maybe that's what Selena was planning on using. She knew it existed, she had years to get it working.
- Kara Danvers: Get what working?
- Alura Zor-El: The transmat portal. Your father had been developing it to get every Kryptonian off the planet before it exploded. But he failed.
- Mon-El: Where's the portal now?
- Lena Luthor: You're doing great.
- Ruby Arias: You look better already.
- Samantha Arias: You're such a bad liar. But I am grateful for that.
- Lena Luthor: Okay, Sam, I need you to count to three, and then look at us.
- Samantha Arias: One, two, three.
- [Lena activates the scatterfield]
- Samantha Arias: Yes, you're waving. Is that supposed to mean something?
- [Lena deactivates the field]
- Samantha Arias: What? What's going on?
- Lena Luthor: It's a refractive scatterfield. It's basically an eye test.
- Alex Danvers: If your cells were expressing in a Kryptonian manner, then you wouldn't have been able to see us. I mean, your eyes would have hurt just trying to even look through.
- Ruby Arias: So the sunlamps aren't working?
- Samantha Arias: Okay, so what's next?
- Lena Luthor: Well, environmental factors can influence gene expression, turning it on and off. Maybe this Harun-El can rewrite the process. I could take this blood back to the lab and see if the Harun-El will rejuvenate your cells.
- Alex Danvers: [Lena leaves] We're gonna figure this out. I promise, okay? Stay strong.
- Mon-El: The portal doesn't look so bad. Selena and her witches had it mostly working.
- Kara Danvers: Well, even if we get it up and running, we'd need another portal to transport to.
- Mon-El: Well, they have one in the DEO. We just have no way to contact them.
- Kara Danvers: Are there any crystals here? I mean, maybe we can contact them the way we did Selena.
- Alura Zor-El: All he had are these. Kryptonian cache crystals, like the ones I put in your pod.
- Mon-El: I've seen those in the DEO.
- Winn Schott: [alerted to a security breach] Whoa, whoa. That... that's weird.
- [entering a secure room, he sees it's empty]
- Winn Schott: Okay.
- [he turns and sees a hologram of Alura]
- Winn Schott: Oh, god, no. No! Oh, you're creepy. AI malfunction. Okay. Be gone.
- [he taps on his tablet; the hologram vanishes, then re-appears]
- Winn Schott: Whoa! Will you stop, please? You're... you're fully wigging me out.
- Alura Zor-El: Winn.
- Winn Schott: What?
- Alura Zor-El: Winn, it's Kara. I need your help.
- Winn Schott: Okay, not only are you now appearing at will, you are fully schizophrenic.
- Mon-El: It worked. Portal's on. Now just fire it up and bring us home.
- Winn Schott: All righty.
- [an alarm goes off]
- Kara Danvers: Winn?
- [the portal turns off]
- Kara Danvers: Winn, what happened?
- Alex Danvers: We got this.
- [leaving with Demos]
- Alex Danvers: Come on.
- Winn Schott: You guys, I think the Dark Kryptonians are here.
- Selena: We were drawn by the blood of our fallen Worldkillers. Hand it over, and we won't spill yours.
- Alex Danvers: Get the blood. It's in the lab. Destroy it.
- Demos: You got it.
- Alex Danvers: [raising her gun to the Kryptonians] Didn't they teach you how to knock on Krypton?
- Winn Schott: Hello. Hello? Mon-El, can you hear me?
- Alura Zor-El: It's Kara's mother.
- Winn Schott: Listen, we have three Kryptonians that have just attacked us. We really need your daughter to come back, like, ASAP.
- Alura Zor-El: Your friend was back, but now he's gone.
- Mon-El: We need to know what's going on there.
- Supergirl: Let me try.
- [the Alura hologram activates in the DEO]
- Supergirl: This is the hologram's point of view.
- Mon-El: Okay, now we know what's going on. Can you get their portal online?
- Supergirl: I'm trying.
- [the hologram tries to activate the portal, but its hand passes right through the panel]
- Supergirl: Well, that's not good.
- Alura Zor-El: Vita.
- Vita: Alura. How did you survive?
- Alura Zor-El: I'm faster than I look.
- [Alura leaves, and Vita follows her]
- Supergirl: She took the bait.
- Ruby Arias: Mom, we have to go.
- Samantha Arias: I'll be too slow. You go, baby. You go.
- Ruby Arias: Well, I'm not leaving without you.
- Samantha Arias: I'll distract her. You go.
- [Ruby activates the scatterfield]
- Samantha Arias: [huddling together] Come here.
- Dark Kryptonian: You can't escape me for long.
- Lena Luthor: [on the phone] I am so sorry, Alex. You just keep monitoring Sam, and I'll keep you posted on my end. Okay. Bye.
- Eve Teschmacher: More bad news?
- Lena Luthor: Yeah. Sam's no better. And there are three people in National City with the same powers as Supergirl that just murdered somebody.
- Eve Teschmacher: Oh. That is not good. And my news is no better. I re-worked the Harun-El to try and jump-start Sam's blood cells like you asked, but they're not responding. They're getting weaker.
- Lena Luthor: Well, maybe I can adjust the ratio of the solution we used and re-inject Sam.
- [putting Sam's sample on a slide and putting it under the microscope]
- Lena Luthor: This should still have the blood of Reign and Sam on it.
- [seeing the results on the monitor]
- Lena Luthor: I think I know what's wrong with Sam.
- M'yrnn J'onzz: Before the fires, there was your birth. A gift from H'ronmeer, who forced me to lift my head up out of the scriptures, and to have a life. Since I have been here, I have tried to teach you balance. I pray that now, as we journey together, entwining our consciousness, you will truly understand.
- Mon-El: Can you imagine if we had Reign to deal with?
- Lena Luthor: Unfortunately, I think we do.
- Alex Danvers: Sam, you should be in bed.
- Samantha Arias: I need to be here. This involves me.
- Lena Luthor: I know why Sam's sick.
- [showing them her tablet]
- Lena Luthor: Okay, these are Sam's blood cells, and these are Reign's. Sam's blood cells are getting weaker, while Reign's are getting stronger. They share a symbiotic, non-local entanglement. Reign and Sam are still connected. Reign's back and she's getting stronger by the minute.
- Supergirl: But I destroyed the Worldkillers' blood.
- Winn Schott: Demos gave his life to stop them.
- Lena Luthor: Well, I don't know how, but they have it.
- Mon-El: Well, if... if Reign is getting stronger, then couldn't the opposite be true? If-if Sam gets stronger, then Reign would get weaker.
- Lena Luthor: Yeah, my thoughts exactly.
- Alex Danvers: But how? Nothing we've tried has worked.
- Alura Zor-El: The Fountains of Lillith.
- Supergirl: The fountains of what?
- Alura Zor-El: Years ago, when I sentenced Jindah Kol Rozz to prison, she spouted about vengeance. One fountain gave infinite strength. The other brought weakness. She spoke of a woman born of the fountain with the power of destruction.
- Supergirl: Reign was created in the Dark Valley, and she doesn't get her powers from the yellow sun. Maybe she got them from this fountain.
- Samantha Arias: Then it's settled. I'm going back to the Dark Valley.
- Alex Danvers: Sam, you're too weak.
- Mon-El: We don't have Brainy to get you there.
- Samantha Arias: Lena was able to do it.
- Lena Luthor: That was using electric shock, and in your current condition, Alex is right. I don't know if you'd survive.
- Samantha Arias: Well, that's a risk I'm willing to take if it means ending Reign and saving the world. And I have to do it for my daughter. I promise you, I am not dying today.
- Alura Zor-El: Your friend Sam is strong.
- Alex Danvers: Well, she's fighting for her daughter, like you.
