"That was a very sick creature. And what's odd is that I can't find a virus or infection of any kind." Alex says as they brought in one of the birds that died.

"Something must've done that." Kara states.

"The Blight." Imra tells them.

"We went through this on Winath. The Blight starts with mass wildlife death, and pant life, crops rotting in the Earth." Mon-El lists.

"Soon it will manifest in people." Imra continues.

"Short incubation period. 100% fatal and extremely contagious." Mon-El goes on.

"Based on my tests, whatever this bird had, it want transmissible. Not even bird to bird." Alex assures them. "So it had to have come in contact with Pestilence herself."

"It might not be contagious yet, but if Pestilence gets stronger, even half of the strength of Blight, the entire city will get ill in the matter of days." Imra warns them. "Now remember, the cure is written in our DNA. With Brainy's help, we'll be able to extract it, weaponize it, and use it to kill Pestilence before she becomes Blight."

"Whoa, Whoa, we're not killing people." Kara informs her.

"We went too aggressive with Purity, and that's when things went bad. We can't do the same thing again." Peter agrees with her.

"There's a human side to Pestilence, and we're gonna find and save her." Kara finishes.

"We came here to end the threat to our time." Imra informs her. "And that means ending her in this time."

"It's not how we operate." Kara replies.

"That's not how I usually operate, but these are extreme circumstances." Imra states when someone walks in and they all raise their weapons to him.

"Who's this guy?" Peter asks.

"Whoa, guys, it's Brainy." Mon-El says and they're confused since he looks human.

"Oh, of course. I'm wearing a personal image inducer." Brainy says as he shuts it off and reveals his normal form. "I had to purchase some apple cider vinegar, and I nearly caused a riot at the Piggly Wiggly." Then he reactivates it. "I thought this would help me fit in better."

"Did you get that from my labs?" Peter asks.

"I borrowed some of your tech that we used to make this in the future." Brainy says and Peter is surprised that he could do that with his tech that usually doesn't work without the suit.

Winn then comes in with news when he look to Brainy and automatically knows who he is. "The mayor, chief of police, five city councilmen are all sick. High fevers, bloody noses. So either it was sushi day at the cafeteria or..."

"It's her. Let's go." Imra says when Kara stops her.

"We have sick people now. So, let's go run some tests on them. Meanwhile, you guys extract the cure so we can help them." Kara tells them and they make their way to the city hall.

-

"It's a nightmare, it happened so fast." The mayor says from his hospital bed. "My chief of staff and the councilwoman, we ordered a quarantine immediately."

"You did the right thing." Kara assures him. "You rest, we've got this."

They walk away and they noticed the mark on his hand and they wonder if that's how everyone is getting sick.

"As you can see, most of the patients have scratches, but none of them remember being scratched." The Head doctor tells Alex and Peter.

"They probably didn't even notice it, meaning it was done discretely." Peter tells them.

"We think it's the origin of the infection." Alex tells her.

"Well, if you're sure it's not contagious, then I need the quarantine lifted and the patents transferred to the nearest trauma facility." The head doctor tells them.

"We have a lead on the treatment." Alex assures her.

"Already?" She asks.

"We work fast." Peter assures her as she leaves and the others join them. "We need to lift the quarantine."

"If the same thing that happens to the birds, happens to these patients, they could descend into catastrophic organ failure." Alex informs them.

"There's a possibility that Pestilence is still here." J'onn says.

"I couldn't find anything with my scanners to indicate anyone not human from any of the people here." Peter informs him.

"Mon-El did say that there's an incubation period, but those scratches do look new. But she probably left as fast as she could." Alex agrees.

"Let's get all these people to the hospital and J'onn, Spider-Man, we cal fly the really sick ones." Kara tells them.

"All right people, let's keep this calm. The last thing we need is a panic." J'onn says when Peter looks outside where people start screaming.

"You mean like that?" Peter asks as they see Imra activated a force field that isn't allowing anyone in or out. "So much for avoiding a panic."

Kara walks up to Imra to shut it down. "Take down the force field."

"Did you find her?" Imra asks.

"Take it down, now. We have to get these people to a hospital." Kara tells her.

"Is Pestilence here?" Imra keeps asking.

"There's no sign of her now. Just scared people who need medical attention." Kara informs her. "Take it down!" Imra then uses her powers and shuts it down. "Shouldn't you be working on the cure?"

"Brainy and Mon-El are getting the transfer set up now." Imra tells her.

"Well, we can handle this." Kara replies, not needing her to cause more of a panic.

"You say that, but you do not know what you're up against." Imra promises as she leaves them to work.

-

"So, Winn is running through security footage to see who came in contact with everyone who got sick." Kara tells Peter as they're back at the DEO.

"And Brainy, Imra and Mon-El have extracted the cure, and are manufacturing doses as we speak. So it's just a matter of time before we catch her." Peter promises and sees she's getting annoyed with Imra. "Hey, listen, I know you're getting frustrated with Imra, but there's a chance she'll understand and come around. She can have some good information on how we can stop her."

"Yeah, to kill her." Kara scoffs. "We don't kill. I mean, we know it's possible to reach them. You of all people understand how important it is to help whoever's inside Pestilence."

"Yeah, and that didn't just happen. I saw it, I heard you talk about the human side of Reign, the woman I was ready to beat down the first chance I get after almost killing me. But now I know she's using someone else, a human side. I know we need to help them. You just need to show her that." Peter offers as advice.

"I'm trying, she's being irrational. Just not listening to me." Kara says when Winn comes running at them with news.

"I think I found her! Okay, so there was one person who came in contact with everyone who got sick at the mayor's office. Adily Swantser, known for her famous lemon puppy seed cookies." He shows her photo to them.

"A Worldkiller that bakes cookies. Okay, I've seen it all." Peter says and Kara recognized her as the scared girl from city hall.

-

The two heroes flies off to her apartment, but when they arrived they saw her on the ground and Imra standing over her.

"Imra! Get away from her." Kara tells her as they approach to see she's dead.

Peter does a scan and sees this wasn't Imra's doing, and he sees she has the scratch on her hand.

"Not Pestilence, another victim." Peter informs Kara who looks to Imra.

"How'd you know she was here?" Kara asks.

"Brainiac-5 has all the same data you do." Imra explains.

"So you came here without telling me." Kara clarifies when the DEO barges in. "Stand down. It's the wrong person, she's human." She tells them.

Peter retracts his mask and rubs his face as he starts to feel light headed as he wipes his face.

"Peter?" Kara calls out with wide eyes as if she's shocked about something.

"Yeah?" Peter replies looking at her and his nose is bleeding.

"Your nose."

"My nose?" Peter asks and feels his nose and sees blood. "Oh...look at that." he then drops from exhaustion.

-

They quickly rushed Peter back to the DEO to get him treated.

"We're giving him the Legion's cure and he should fine." J'onn tells them.

"Which by my calculations should have him rebounding in approximately 2.45...three, four hours." Brainy tells them.

"How you feeling, Peter?" Alex asks him.

"Spaced out." Peter answers as he feels seriously light headed.

"The scratch on your hand seems to be the point of infection." Brainy says as he grabs Peter's hand.

"Don't touch that." Kara and Alex warns, not knowing if it can be transferred by touching the cut.

"Pete, you have any idea as to who did this?" Winn asks him.

"Yes, Peter Parker, you're a slightly smarter than average human." Brainy agrees and faces Peter. "Please tell us you remember who's scratched you."

Peter seems to be thinking about it for a second looking around the room as he can't focus. "Well, there is the one guy who had these gloves and knives with the burnt face."

"Go on." Brainy tells him while looking around the room to the others. "This sounds like a very promising lead." Everyone knows who's he's talking about and sees this as either stupid or funny. "What else can remember?"

"He was fighting this guy who carries a machete. Oh, and he was wearing a hockey mask." Peter continues.

"It's Freddy Krueger." Winn tells him.

"You know him, too. Eureka." Brainy cheers.

"It's a character in a movie. He's talking about Freddy versus Jason." Kara explains and Peter laughs.

"I now see why my doppelgänger makes those quips, they're fun." Peter says while laughing.

"Facetiousness. It's my greatest weakness." Brainy admits.

"More importantly, you saw Freddy versus Jason?" Winn asks Peter.

"The scratches don't seem to manifest until the symptoms do. And the only trace evidence I could is a mild anesthetic. Yet with Peter, the dosage needed a bit more powerful because of his powers." Alex tells them.

"Okay, I'll get a team out and see if we can talk to these patients and find a common link." J'onn says and they all leave to help and Kara looks to Peter.

"I'll come check in, but there's something I have to take care of." Kara tells Peter while patting his shoulder.

"My brain feels fuhzhee." Peter tells her and Kara chuckles at his behavior.

"Hang in there, you'll be back up in no time." Kara promises as she leaves.

"And she vanished." Peter whispers to himself. "You invisible?"

Kara and Imra have a talk and it appears that Blight kills dozens of people and her sister, that's why she wants to kill Pestilence.

Kara understands why, but knows that not the right way to defeat the Worldkillers.

Later, she's watching Peter as he's sleeping off the sickness and J'onn joins her.

"He's gonna be okay." J'onn assures her.

"I know. It's not just that. Do you think I'll get through to Pestilence?" Kara wonders.

"There's no way of knowing. You just have to try." J'onn says.

"That's not what Yoda would say." Kara jokes.

"Oh, yeah, Yoda. Do or do not. He was wrong about that one." J'onn says and looks to Peter waiting for him to make a joke or reference, but he's just resting. "Just because something's hard, doesn't mean it's impossible. You break through impossible every day. You inspire the rest of us to do the same. You helped Peter keep his light from dying out in his darkest hour. I think that's why he loves you."

Kara quickly spins to face him, shocked how he knows. "How?"

"It's obvious with the two of you. Neither of you know how to keep secrets from the group, especially from me." J'onn explains and leaves them.

"Well, I guess that's one less person we need to tell." Kara says as Peter starts having trouble breathing and they call everyone back.

"I don't think the cures working." Winn says as Alex gives him a sedative to help him calm down.

"What happened?" J'onn asks.

"There it is. I see it now." Brainy says while his three lights flash. "The cure is designed to cure the victims of the Blight. But Pestilence is not the Blight yet, the cure we have needs to be modified to fight her particular strand of virus."

"So how do we do that?" Kara asks.

"We need a piece of Pestilence's DNA." Mon-El explains.

"So if we can't find her, more people could get infected and the people already infected-"

"Yes, finding her as soon as humanly or non-humanly possible would be..." Brainy was saying when Alex dropped and she has the sickness. "Imperative." He finishes.

They have Alex on the bed across from Peter and they need to find Pestilence fast.

"Skirt..." Peter calls out and Kara walks over to him.

"Hey, I'm right here." Kara assures him.

"Worldkiller...might have a lead..." Peter tries telling her.

"What? How?" Kara asks.

"Say hello to a friend of mine." Peter says as a little Spider-Drone crawls up his face to where Kara can see him.

"What's that?" Kara asks as she picks up the little bug and sees it's a robot.

"It's my spare eyes and ears. He sees and records everything I see from all around me. It's recorded into my labs." Peter tells her. "Now...go get that Pest Silence. Pests instinct? I can't remember what we call her."

Kara finds it funny and leaves with the drone to find Brainy and Winn and tells them what Peter told her and he goes through the footage.

They watch when the drone watches everything going on at city hall and they see the doctor they were talking to earlier was there and that could be their lead as she shook their hands where the cuts are.

"Dr. Grace Parker, first in her class at Metropolis University school of medicine, now practices emergency surgery at National City General." Brainy tells them.

"A doctor is our Worldkiller? That's ironic." Winn says.

"She wants to help people, I can use that to get through to her." Kara promises. "We can't make the same mistake like with Julia."

"Is she still at the hospital?" J'onn asks.

"Actually, according to a simple scan of security cameras throughout the city, it seems she entered the silvermine health insurance building five minutes ago." Brainy tells them.

Everyone heads out to find her and Brainy secretly contacts Imra and tells her where she is.

-

Kara stops her before she could harm another person.

"Don't take another step, Grace." Kara warns her.

"Is not Grace anymore." Grace informs her as everyone leaves the room. "You would save even these scabs? They who gain from the suffering of others?"

"Everyone deserves saving." Kara tells her.

"Not them. They're not good." Grace states.

"But you are." Kara says when Imra reaches them and Mon-El keeps her back for a minute to give her a chance. "Think do the lives you've saved. You're a doctor, Grace. The day you took an oath you swore you would do no harm."

"Do no harm." Grace repeats and shrinks her nail finger and Kara sees she's getting though to her as her eyes go to normal. "My mother used to always say that good would be rewarded with grace. But when I became a surgeon I finally saw the truth. There is no reward for being good."

"Whatever's happening to you doesn't give you the power over who lives." Kara says as she circles the table. "Only over who dies. You don't want that. We can stop it." She reaches her hand pit and Grace puts her arm on it.

"Stop it. Why would I ever wanna stop it?" Grace asks her. "This is the greatest thing that's ever happened to me. I don't have to be afraid of saving anyone because I don't want to. I get to choose who dies. They say surgeons have a god complex, but it's simple. I am a god." She says and goes to stab her when Mon-El wraps his cape around her arm and he gets thrown around the room.

Imra throes aims chairs and Grace dodges them before Kara pushes her through a glass window and she drops to the main floor where Kara meets her.

"You honestly thought you could talk me into being redeemed?" Grace wonders. "You're such a child. Words will never hurt me."

"What about sticks and stones?" Kara asks as Imra is dropping everything from above onto Grace to stop her and Mon-El slams her into the air where she and Kara continue to fight when Kara feels she was cut and drops.

Imra was able to trap Grace and shoots a dart at her before shutting down the forcefield.

"She's here." Grace warns when Julia comes flying in as Purity comes in and is dressed up in her Worldkiller suit before shrieking at the heroes and takes off with her sister.

The good news is because of the dart, they have a sample of her blood to use and save everyone.

-

Alex and Kara were the first to be healed and Peter wakes up and sees Kara, J'onn and Alex standing over him.

"Tell the the truth...are we dead?" Peter asks them.

"No, we're not dead, and neither are you." Kara assures him.

"Did we stop her?" Peter wonders.

"No, but we will." J'onn promises.

Peter and Kara smile and Alex notices how they're looking at each other. "You guys gonna kiss or something?"

"Well, now you mention it." Peter says as he gets up and kisses Kara who kisses back, happy he's okay and Alex is a little surprised.

"I was just kidding, but okay." Alex mumbles.

"We were going to tell you guys, it was a while back." Kara tells them.

"We just never found the best time." Peter says as he lies back down. "Now excuse me; I'm gonna keep sleeping and wait until I can see straight to get up."

That was before they learned that they were heading to L-Corp and Peter jumped back into action.

-

When they arrived at L-Corp, J'onn got them to what was apparently a secret bunker where Sam was being held in a forcefield cell.

"What..is happening?" Peter asks Lena.

"I was gonna tell you all." Lena promises.

"Tell us what?" Kara asks.

"About me." Sam says, but in reign's voice as said Worldkillers walk in and shut down the forcefield and Purity keep them back until Reign wakes up.

The five heroes get up and ready to fight the three when they release a wave and they're all in their suits and frozen.

"El-may-ara." Reign says m which is Kryptonian for stronger together as they fly off.

Leaving Lena with some explaining.
