CHAPTER 4: Agreement

"Are you positive you've seen him, Agent Danvers?" Asked J'onn.

Alex and her team were analyzing surveillance footage and media recording from the attacks.

"I do, I saw that guy the day they tried to detonate everything during the hockey match."

"Ma'am, I attended the day the fire was informed; the one in which Supergirl disappeared." Spoke agent Richards. "That man was the last victim rescued out of the house. He had a wound in his left leg and a small concussion; he came out of the hospital three days later."

"The fire was five days ago." Concluded J'onn. "Agent Scott, get me his record. As a patient, and as citizen."

"Right away." Winn sat back down on his chair.

The Martian spotted Alex frowning in front of the screen, following her team associations of the scene; clearly, they were already finding patterns.

"How did it happen?"

Alex snapped out of her thoughts when she heard J'onn's voice. "Sir…" She took a deep breath, asking the other agents to give her space. "Attack number one, the festival. Everything seems normal, then we have the man with the gray hoodie; he has a girl no older than seven holding his hand. According to records, she is his daughter. They seem normal, until this other blonde woman passes by his side, giving him what looks like a teddy bear. The next we see is the man keeping the bear in his hand while he walks towards the hotdogs cart; in there, he hands the teddy bear to his kid; more people are in line for a hotdog; while he pays for the food, the little girl places the bear next to the small gas tank. After that, both walk away eating as if nothing has happened."

"How did you discard the hotdog cart?"

"It went through a filter to prove things were clear. According to legislations, a children parade has different standards, very strict standards of security for food and entertainment. A kid carrying a teddy bear is a clever move, and a good place to hide a bomb, plus place it next to a tank to have higher potential."

"You do realize that little girl is part of a crime, don't you?"

"I do, Sir." Alex nodded nervously. "I'm also afraid the list continues with the festival, where the second attack happened. This scenario was slightly different considering the bomb was carried in a boy's toy, a green truck… The third attack, that one was a massacre, people simply thrown grenades at the crowd. The police department has suspects, but none of them confirmed yet."

"I got him!" Winn raised his hand, turning on his chair to gesture Alex and J'onn to approach him.

"What have you got?" Alex was the first one to reach his desk.

"Anthony Sheedy. 24 years old, tan skin, hazel eyes, dark curly hair. Graduated from National City University, he's a chemist."

"Probably the one who helped to create the bombs…" Supposed J'onn.

"The other people involved, those we can see in the footage… I don't recognized them; however, I assume Anthony is their only chemist, he had to be in the scene to guarantee the plan would work. The teddy bear one was easy, it just needed a sparkle to use the gas for its benefit, but the toy car was different, the festival was public; filters were pretty much none, I assume the complexity of the bomb was perfected in order to detonate by itself." Explained Alex.

"Has he been seen lately?"

"I already have a facial recognition plug on the run, Sir."

"Agent Danvers." A female agent interrupted.

"Yes, Dalia?"

"We have Jeremiah Danvers at the main door asking for you. He handed himself to the DEO."

"Why is it not working, my goddess?!" Walter was exasperated talking to Kara, sweat covering his forehead.

The scientist took a scalpel out of his pocket to make a small cut on his forearm, from which a darker than human, blood emerged.

"It's still poisoned!"

"What if you altered her immune system alongside the compound you used to neutralize her powers?" Suggested Tony.

"SHUT UP!" Walter turned around and grabbed the intimidated chemist by his t-shirt. "Don't you think I know what I'm doing?!" He pushed Tony to the wall, then started to walk in Kara's direction.

Lena started to laugh under her tape to distract him, something that made the man angrier.

Walter could be a man around his fifty's but he looked as strong as a young man. With a clenched jaw, he went after Lena.

"Walter, stop!" Kara called him trying to stand up, but her legs failed.

"What are you laughing about?" With a rude move, he grabbed Lena's chin.

The Kryptonian didn't have her powers, but she didn't need any special vision to notice Lena's skin was even paler than usual. Her breathing was erratic and by judging her posture, ties and everything, she saw the Luthor was contracting her torso, trying to move it as carefully as she could.

Her ribs…

"You're not in the best position to laughing, Luthor." Suddenly, Walter went too close to the point where he started to smell the skin of Lena's face.

"LEAVE HER ALONE!" Yelled Kara as her anger boiled.

The CEO pulled back disgusted by the contact; but the man kissed her cheek, removing the tape, getting a flinch from Lena when the cut on her lip was stretched.

"You'll help me to create an antidote." Said Walter with a threatening tone.

"Like hell..." Replied Lena and her response transformed into a gasp of pain when the man touched her ribcage.

"LENA!" Kara tried to get Walter's attention back.

"Did you believe I didn't notice? The way your body is positioned, your breathing, your skin, your pupils…" He leaned to say next to her ear, in a lower voice. "You think I haven't noticed the way you look at her…" He put distance between them again.

Lena hardened her gaze towards him.

"Now, dear traitor of Rao… You're a genius, aren't you? You will help me to develop an antidote for myself; on the contrary, I would have to drain our beloved daughter of Rao until I find the antidote myself."

"She's your goddess. You can't dispose of her like that." Said Lena.

"Her purpose is to save others; my goddess is selfless, my goddess is salvation; she will indeed serve her purpose by saving me and after that, saving others through me, with my knowledge… no matter what it takes."

"What is this for, Jeremiah?" Asked J'onn on the other side of the table, next to an uncomfortable Alex.

Jeremiah's first reaction was to use both hands to explain, except the chains and handcuffs broke silence.

"I know Kara is missing."

"Most citizens in National City are aware of Supergirl's absence." Commented J'onn arms crossed.

"Look… I know neither of you have reasons to believe in my words anymore…"

"You stabbed our back." Henshaw pointed out.

"I'm responsible for my actions, yes; but Kara isn't and things have distorted."

"What do you mean Kara isn't responsible for your actions? What did you do?" This time Alex's behavior changed, transforming her into a determined agent, alerted by news. She stretched her back leaning towards Jeremiah to place a couple of serious eyes on her father.

"I believe I know what she's going through."

"Speak clearly, Jeremiah." Demanded the Green Martian.

"I tried to reach you with anticipation," he headed Alex, "but I couldn't know how soon things would happen." He then looked at both. "You're probably looking after a man called Walter Johnson, a biologist who used to work for Cadmus… We used to work together."

"What does this has to do with the Cult of Rao? They left a flag at the scene." J'onn frowned.

"He, as many others, lost his mind between research and experimentation regarding specific abilities from aliens; therefore, one day he did a test on himself… and things went wrong. We were sort of colleagues…"

"Of course." Nodded Alex with sarcasm.

"Later I knew they had captured Kara alongside Mon-El. I knew what Cadmus was planning to do after getting access to the Fortress of Solitude. Walter was anxious to put his hand on them, of course I couldn't allow that, so I helped them scape."

"Then they got you again and used you as bait so you could infiltrate the DEO and betray us." Concluded Alex.

"Honey, there were lives at risk…" He gulped. "As time passed by," he changed the conversation, "I found out about the Cult of Rao; I wondered what it was and if it represented a threat for Kara and Clark. It did. I realized it was even more dangerous when I saw Walter as one of the main heads of the movement. He used to talk about genetics, cure for diseases, anatomy; he even shared knowledge from Cadmus. I hid myself amongst the crowd and… the ideology got twisted; having Supergirl and Superman in service to Earth wasn't enough, they started to go for the source, to go after Rao."

"I saw the way they worship Rao; the hope they put on Kara. Why kidnapping her? How was a human capable of capturing Kara?" Alex was still not entirely convinced.

"Because of me."

"What do you mean?

"I believe to know how he was able to capture her… Do you remember that time Supergirl attacked the city? The day J'onn Jones revealed himself?" Jeremiah looked at Hank.

"The red kryptonite."

"Yes. When it happened, Cadmus wished to show itself to the world and reduce credit to the DEO, to appear as the heroes so new alien regulations could be proposed." Realizing Alex and J'onn were not entirely following him, he tried to explain things better. "Alex, you witnessed when Kara's powers emerged, the struggle she went through. I designed those glasses to restrain her x-ray vision… but that wasn't my only research."

"What did you find out?" The Green Martian started to walk around him.

"As some days containment for Kara's powers got harder, I looked after a way to reduce solar radiation in her system, to help her."

"To make her weak?" Declared Alex.

"We could not keep her in the basement under a red sun light emitter for hours…" He countered.

"How did it work?" Hank tried to break tension.

"It was a chemical process based on the way photosynthesis operates in flora, only the opposite… When the red-k happened, Cadmus used my research as resource to create a solution to contain Supergirl; Walter, as the main biologist, was assigned to develop the substance, so it could be placed in darts."

"You gave them a solution to get rid of Kara?!" Alex lost her patience. "You don't even have to explain about how you were 'forced' to do it." She bluffed.

"They obtained that knowledge since the first day I got in, they knew everything about my work; I couldn't even oppose to it." He lowered his gaze. "Recently, after a meeting of the Cult of Rao in which Walter promised his followers to be in the presence of Supergirl, I knew there was something suspicious behind it, thus I hid and I heard some keywords related to my research." His eyes locked with Alex´s one more time. "That's the reason I tried to reach you, but now we're out of time… Walter is brilliant, but I never really tested my own creation, I'm concerned about his progress or success regarding a Kriptonian's physiology." He made a pause. "I know Kara's possible location."

"Walter." Amanda stood by the doorframe, serious and strangely tense.

Without releasing Lena, the biologist glared Tony and the guy went to listen whatever the woman had to say. She left and Tony went straight to where Walter was, nervousness suddenly present in his attitude.

"What?" Asked the man.

"All children events have been canceled." He replied playing with his fingers to reduce tension.

"As expected." Walter shrugged.

"Wait… what?"

"Why do you think our next… fireworks location is the mall? Let's go for bigger… I mean, older leagues."

"You can't attack the mall…" Lena went into their conversation but Walter slapped her again. Forcing a painful cry when he torso involuntary moved.

"Shh! How disrespectful…"

"You will what?" Questioned Kara from her spot.

"It will all be over soon my goddess." The man gave her a warm smile.

"No… Walter, this isn't the way… Look at me."

"Rao is the way, I'm just clearing the path for him to come."

"Rao is light and love, you are dishonoring his true nature by harming others." Kara tried to make him understand. "I stand for hope, for compassion, for love; that's Rao's light."

"My benevolent goddess… I believe a life amongst humans has corrupted you already."

"Stop this Walter!" Supergirl commanded after lost patience, struggling a bit to raise her body and chin, claiming respect. "You speak in the name of Rao as if you were a priest devoted to him, when in real facts you destroy, you kill…" Even her eyes were hard as she spoke. "Let me tell you something, human…" she said it like that to show a fake superiority, "you might be brilliant for sciences; nevertheless, you use them to hurt, to please your own ideologies. Rao… my Rao, must be ashamed to have a being like you speaking in his name. Stop this nonsense before Rao comes to do justice; who do you think you are to use your own hands in the name of Rao's will? You are not dignified for your actions, you are a mere human and as painful as it feels, you are not a Kryptonian!"

Silent was left after Kara's words. She was trembling in anger, regretting what she had just said without putting a filter in her mind; she had let herself be taken by emotions.

Fearing for a vulnerable Lena under a serious Walter, she made the best she could to look powerful.

"Proceed with the attack." Was Walter's order for Tony without taking his eyes from Kara, without blinking, without breathing.

"N-…" Kara was about to say something when Lena's voice broke in.

"I'll help you create the vaccine; in exchange stop the attack."

Finally, the man's eyes went back to her.

"Exchange?" He asked intrigued, a smile of sarcasm on his face.

"You want to save others, don't you?" Lena started to negotiate, buying them time. "You think I haven't seen the trembling, the erratic breathing, your limbs barely noticeable failure, the sweat dampening you face… You need this vaccine as soon as possible, if you want to accomplish your purpose."

"Lena…" Kara didn't want her to be at risk; even more knowing her friend was injured.

"Luthor, we have an agreement." Walter kissed her cheek, making Lena close her eyes and take a deep breath avoiding nausea. "Shall we untie you?"

TBC…
