Alex whirled on Lillian as soon as the door shut. "What the hell did you do to Superman?"

Lillian feigned ignorance as she replied,"I have no idea what you're talking about." All the while speaking with a smug grin on her face.

Kara remained silent, trying to reign in her anger and keep it in check. As a result, Alex spoke again while stepping closer to the clear cell. "I swear to God, if you don't tell us right now what you poisoned him with, I will personally go in there and I will-"

Hank smoothly interrupted. "I see you don't have the little Green Bean in here to keep you girls in check like last time. This could get interesting. God forbid you actually decide to come in here. He prevented you from getting your asses kicked last time, but we'll see what happens when the little alien gets beat by me again."

Kara's face contorted in rage as she remembered the amount of times Hank had beaten her, tortured her, left her on the brink of death. She wanted so badly to go in there and beat the living crap out of him, but she knew they wouldn't get any information if that were the case.

Alex, however, did not apply the same rationale.

She opened the cell door with a ferocity Kara had never seen before, and started smashing her fists into Henshaw's face. He was taken by surprise, mostly because he did not expect her to call his bluff, but also because he hadn't realized she was actually skilled in combat.

Once he was knocked to the floor, Alex rounded on Lillian, delivering a ferocious uppercut to her stomach. Lillian doubled over, gasping for air.

Kara had been frozen from shock, but knew this couldn't continue. If she left them in there, Alex would kill them. Then they would have no idea how to help her cousin.

She super sped into the cell and grabbed Alex. She held her older sister's arms at her sides and hugged her, in an attempt to calm her down. Alex was breathing hard, and she was fuming. She had been waiting weeks to do this.

Kara tried to talk her down. "Lex, shhh. Calm down, it's okay... You can't do this, you can't stoop to their level. I know you, and this is not who you are. If you kill them now, you're giving them the easy way out. It won't be sufficient punishment for what they've done if you end them right here, right now. You have to calm down, please. For me."

Kara could see she was getting through to her big sister. "If we kill them both now, we'll have no way to help Superman, and I know that's not what you want. If you kill them, you're getting rid of our only source of information on Jeremiah. As much as I hate to say it, they're too valuable to get rid of just yet."

Alex remained tense for a second longer, muscles taut, before relaxing in her little sister's embrace. "I'm sorry, Kar. I shouldn't have done that. I could have ruined everything... I'm so sorry."

Kara stroked her sister's hair. "Shh, Alex it's okay. What's important is that you didn't."

Alex whispered, tears streaming down her face. "Thank you for stopping me."

Kara just nodded and held her.

Lillian rolled her eyes from the cell, having regained her composure and her breath. "Uh, as touching as this is and all, I personally find it repulsive and revolting. If we could get along with it and have you guys take this somewhere else, that would be greatly appreciated. Perhaps you two could get a room."

Alex stood tall, fists clenched. "We'll leave once we have the information we need."

Lillian glanced over to an unconscious and bloodied Hank. His cybernetics wouldn't work in their power-dampening cell, and he was of no use unconscious anyways. If the sisters decided to attack, there was nothing she could do.

She begrudgingly told them what they needed. "We gave him a synthetic form of kryptonite called Red Kryptonite. We developed it from the blood and DNA samples we took from that thing you call a sister. We weren't sure if it would work the way we wanted it to, but judging by your reactions, it did. He was our first test subject and it turned out to be a success."

Kara was fuming. "Just tell us how to get rid of it. Tell us how we can cure him."

Lillian explained. "The kryptonite causes his frontal lobe to morph temporarily, lowering his inhibitions. He essentially has no filter, and has no idea how to tell right from wrong. We accomplished this by reversing the polarity of the ionic charges in the chemical compound, so you'll need to find a way to change it back. Then a couple hours under some sun lamps should do it."

Kara looked to Alex to see if what Lillian had said made sense. When Alex nodded, Kara turned towards the door. Right as the sisters were about to leave, Lillian called out. "You might need my help with your cure, or maybe some special equipment that only I have access to. I can be of use if you-"

Alex turned back, fire in his eyes. "If you think for one second you are getting out of here, you are horribly mistaken. As long as I'm here, you won't be getting out any time soon."

Lillian resigned herself to her fate for the time being, and the sisters left. They made their way to Alex's lab and got started right away. Kara asked,"Do you know what you have to do?"

Alex slowly nodded, going through a mental checklist. "If I can separate the charges, the ionic bonds will break apart... separating ions... neutralizing kryptonite... Just need to inject to bloodstream... circulatory system will carry... frontal lobe... Yeah, I think I got it. Just gimme a couple minutes."

Kara nodded, not knowing anything about what her big sister had just said. Unable to help, she turned to the TV screen showing the security feed monitoring her cousin's room. He seemed to only be gaining ferocity as the time went by. He could be seen using his heat vision on the glass, trying to use his freeze breath, and even just slamming against it, in hopes of breaking the unbreakable clear glass.

She turned to Alex, worried. "Please hurry, I don't know how much time he has. It might become permanent."

Alex nodded without looking up. As she put the finishing touches, she prodded slightly. "You seemed pretty composed in there, or at least more than me. I'm glad you were able to be so level-headed and calm in their presence. Are you okay?"

Kara shrugged. "I was still pissed, but I'm healing. After the thing with Winn, and actually becoming Supergirl full time and helping people, I think... I think I'm getting there."

Alex straightened and smiled at her little sister. "I'm glad you're doing better. They changed you, but it wasn't the worst. You ended up okay, I guess... But of course, only mediocre at best."

Kara playfully protested. "Hey! I am far past mediocre. If anything, you're the mediocre one here."

Alex got back on track. "Mediocre, my ass. I just finished the cure." She quickly grew serious. "Let's go fix your cousin then, shall we?"

Her little sister nodded back at her and they rushed over to Clark's holding cell to administer the cure and end his rampage once and for all.
