Kara had no idea where she was. All she saw was a cage like cell with the Daxemite known as Mon-El in the cell next to hers. Well, she had no idea as she had just woken up. Around her was metal bars and a dimly lit blue light surrounding them.

"Mon-El, what happened?" Kara asked as she rubbed her temple.

Her head was pounding, and she felt like she had a headache. Of course, this wasn't a headache. She was indestructible. She was invulnerable. No way would she call this a headache. It couldn't possible be a headache.

Maybe Hank Henshaw had hit her harder than she thought he could. Kara let out a breath to tell herself she was perfectly fine.

"You were beaten up by the real Hank Henshaw, and we were both dragged to Cadmus. How are you?" Mon-El asked her.

"Well, now I know how it feels when I pummel the bad guys." Kara said.

"What is this place?" Mon-El asked.

"Cadmus. It's an organization where its goal is to wipe out every alien on Earth one way or another." Kara explained.

"And we're the first ones?" Mon-El looked out her from the other side of where he sat in his cell.

"I don't think they're ready yet. They still need more time." Kara took a breath in. "Is anyone else captured or hurt?"

"They have J'onn." Mon-El said.

Kara sighed. How was she going to explain this part to him? Truth be told, she didn't know how to say it where it did make sense.

"J'onn took the image of Hank Henshaw after the real Hank supposedly died. It was his way of staying under the radar, but now he's alive and a cyborg apparently." Kara explained.

"They tricked me. We were the only ones, then." Mon-El explained.

"Why?" Kara asked.

"I have no -."

"Ah, I see you're awake Supergirl or should I say Kara Zor-El." Lillian Luthor walked into the room.

"What do you want with us?" Kara asked her.

"It's not what I want with the both of you. It's what I want with you, Kara Zor-El." Lillian said. "The Daxamite was just here as bait for you."

"And that is?" Kara asked.

Lillian Luthor came up to Kara's cell-cage, and hissed, "I want your blood."

Lillian Luthor looked over at a man with black hair, grey eyes, and a goatee. She nodded her head at him and he came up to the cage and led Kara away to one of the labs.

"Why do you need my blood?" Kara asked as Lillian turned on a switch.

"Because of things I can't tell a superhero." Lillian said.

"I'm-I'm indestructible. I can't draw blood." Kara breathed.

"Unless you release solar flares through your heat vision." Lillian said as one of her scientist brought out a helmet.

"What is that?" Kara asked.

She felt herself getting more weak. She didn't know what it was, but she suspected that some kind of a small amount of kryptonite was in this room. It was making her weak. It wad the only explanation.

"It's a special device to get you to solar flare." Lillian explained.

"And why do you think I'll do what you want?" Kara exclaimed.

"Because I'll end your Daxamite friend, and I have the perfect weapon for the job." Lillian smirked.

Weapon? What weapon did she have in mind to end a Daxamite?

"And if that part won't work, then I'll just send Cyborg Superman after that Agent Danvers." Lillian threatened.

Kara threw a punch at Lillian, but Cyborg Superman stopped the punch. He threw her back.

"Don't you dare touch Alex!" Kara hissed as a scientist helped her off the ground.

Lillian handed the scientist the helmet before smiling. "I won't unless you don't comply."

Kara nodded her head, and they put the helmet on her head. She was doing this for the safety of Alex. For the life of Mon-El. For the continuous saving of the people of National City. For the protection of everyone.

She shot her heat blasts out of her eyes, and she felt herself grow weak. She felt someone take her blood from her arm. Lillian Luthor took the helmet off her head before having someone drag her back to the cage.

"Where's Mon-El?" Kara asked.

"Right here." Mon-El jumped down from the ground and punched the guard.

The gaurd lost his balance and fell onto the ground. In that moment, Kara Zor-El jumped into action. She swung her body away from the guard and threw a punch. She wanted the punch to hit the guard, but he dodged it.

Mon-El was busy defend himself from the other guards that were coming. The guard grabbed her arm and tossed her over. Kara groaned as she landed on a desk. She hopped up from the desk, flew at the guard, and punched him.

The guard fell limply to the ground. More guards descended upon them and the room they were in. The next thing they knew was that someone was blasting down the guards. Kara looked over her shoulder to see someone she never thought she would see again.

He was dead. Or at least everyone thought he was: Jeremiah Jones.

"Jeremiah?" Kara questioned.

"Come with me." Jeremiah told them.

Mon-El looked at Kara wondering who this person was. Perhaps there would be some sign on Kara's face to let him know who this was. Jeremiah Danvers led them away from the room, and went down a hall before turning towards Kara.

"Go straight through that door and you'll be out." Jeremiah said.

"No, no, no. You have to come with us. You need to see Alex, Eliza. They would want to see you again." Kara denied.

"I'm sorry, Kara, but I need to stay here. Just for a little longer. Please, just go through that door, and I'll stay here and make sure no one goes after you." Jeremiah said.

Kara hugged her adoptive father one last time, and she and Mon-El ran through the door. She didn't feel sunlight. In fact, she didn't feel anything that the outside world would have given her. She walked around aimlessly confused.

"Kara?" Mon-El said.

"What?" Kara snapped at him.

"I think you might want to see this." Mon-El said.

Kara turned around to see the Daxamite looking at a pod. But it just wasn't any pod. It was a pod with a boy inside. The words Project Kr were written in big black letters. But there was one thing Kara was sure of.

Cadmus had imprisoned a Kryptonian.

Chapter 2 will be out on Friday, September 28th, 2018.
