A/N: This is a sequel to Prisoner of Prejudice and Overload and will complete the trilogy.

As Kara flew to the scene she looked round and saw four figures hovering in the sky, all clad in black, their faces covered.

"What do you see Supergirl?" J'onn asked over the comms link.

"Four flying ninjas." Kara said slowing her approach.

"Alien?" J'onn pressed.

"Unless humans have learnt to fly." Kara said before adding "They've seen me?"

"Keep your distance we'll be there soon." J'onn replied.

"That may be a little tricky." Kara said noticing all four of the flying figures were heading towards her.

"Do not engage." J'onn warned.

"What if they attack first?" Kara asked.

"Do your best to keep your distance. You are out numbered against unknown hostiles. We don't know what threat they pose to you."

"Fairly sure I am about to find out." Kara said as she noticed she was loosing the battle to maintain distance between them. "Whoever they are, they are fast. And they have guns."

"Don't get shot." Alex warned.

"Really wasn't planning to." Kara said.

"We'll be there is two minutes." Alex replied, the worry evident in her voice.

Before Kara could reply she felt the all too familiar nausea associated with Kryptonite moments before something ripped into her torso. Before she could even register the blood coming from her stomach she plummeted to the ground.

"Kara!" She heard in her ear as she groaned.

"Ughh." Was all Kara could moan out in response, in too much pain to move.

"Kara, hold on we are almost there." Alex said over the comms link, offering some comfort to Kara who was writhing in pain. She got no respite though as she was hauled to her feet before being flung a few feet in the air, before once again landing with a thud.

"I don't know why people fear you." One of the masked men said approaching her before kicking her in the ribs. "You are so weak and pathetic." He added kicking her again.

"Who….are... you?" Kara gasped.

"We are Earth's saviours, humanity's guardians." The man said kicking her again before pressing his foot down on the wound on her stomach causing Kara to scream in pain, barely able to register him aiming his gun at her head as he said.

"Goodbye Supergirl." Just as she lost consciousness.

"Easy." Alex said gently when Kara's eyes opened.

"Alex? Where am… How?"

"I'm right here." Alex smiled squeezing her sister's hand. "You are back at the DEO. We arrived just in time and managed to get you out of there."

"How? Did you get them?" Kara asked.

"No they escaped. I think they decided taking on the entire DEO was a battle they wouldn't win and retreated." Alex explained as Kara hit the release button on the solar emitters.

"They had Kryptonite." Kara said.

"I know. We extracted the bullet." Alex said carefully watching Kara who grimaced as she sat up. "You okay?"

"I will be." Kara said hopping off the bed only to crumple to her knees. Saved from hitting the ground by Alex.

"Easy. You took a lot of damage." Alex warned as she helped Kara sit back on the solar emitter bed. "It may take longer than normal to recover." When Kara didn't say anything Alex brushed a strand of hair away from her sister's face and asked. "You okay?"

"No. I need a hug." Kara confessed causing Alex to wrap her arms round her sister. "I really thought I was going to die." She whispered into Alex's shoulder.

"You are safe now and we are going to get who did this." Alex promised as she continued to hold Kara. "But you need to rest."

-00-

"How's your sister?" J'onn asked as Alex entered the command room.

"Weak, but okay." Alex said. "I've managed to persuade her to lie under the lamps a bit longer."

"Voluntarily? She must be bad." J'onn said.

"I think it really scared her." Alex said. "I'm also worried that there is something wrong."

"Like what? They got the bullet and the wound healed." Lucy stated.

"I know, but she is really weak. Normally she bounces back really quickly, this time she has powers but she is not one hundred percent. Something isn't right."

"She's been through a lot recently." J'onn reminded her.

"I know. That is why I'm worried. What if she has suffered permanent damage from the Kryptonite exposure and the compound that caused her powers to go crazy?"

"Right now we have no reason to believe that." J'onn said. "She probably just needs rest."

"Which she isn't likely to get with four super powered assassins after her."

"Until she is in top shape she is not leaving the DEO. We'll keep her safe." J'onn said.

"You know you may not win that fight?" Alex asked.

"She can't be worse than you." J'onn smiled.

"I'll remind you that you said that." Alex smiled back before asking. "Any luck figuring out who or what they were?"

"Not yet. But there isn't much to go on." Lucy said, but on noticing Alex's expression J'onn added.

"Unless you have something to bring to the table."

"The man who attacked Kara said they were humanity's guardians." Alex said.

"What of it?" J'onn asked.

"They were the exact words Max used to describe Bizarro." Alex said.

"You think they are Max's experiments?" Lucy asked.

"Big coincidence if not." Alex said.

"That would explain the masks." Lucy said. Noticing the questioning look Alex and J'onn were throwing her she explained. "If they are aliens, why the masks?"

"They could look humanoid and want to keep their identity secret." J'onn pointed out.

"Or they are humans and whoever gave them their abilities don't want us to find out that they are experiments." Lucy countered.

"Last time Lord did this he used coma patients. Let's see if we can find any who match the build of these people." J'onn said.

"What about Max?" Alex asked.

"I'm not going to confront him without proof." J'onn said. "Since he created the anti-Myriad tech he has many friends in high places. If we step out of line and illegally detain him we'll be no closer to truth and will have far fewer resources available to us to find out what is happening. For now we'll keep an eye on him. But we won't talk to him until there is proof." Seeing Alex was about to argue he added. "Alex I promise we will find out who was behind this, but we do it by the book."

"Hey." Alex said as she approached Kara's side a couple of hours later. "How are you feeling?"

"Bored."

"I meant the dizziness." Alex said.

"It's gone." Kara smiled. "I am absolutely fine." She went on, but as Alex silently stared at her she confessed. "Until I move, then it comes back, a bit, but only a bit."

"Then you need to rest,"

"But I'm so bored. Can I go home now?"

"Not yet."

"Why?"

"Kara, something is wrong. You haven't recovered properly. Until we are sure you are okay you are not going anywhere."

"But they are still out there."

"Precisely. That is why you are staying here., where you are safe. You have been through so much recently, let us handle this. You focus on getting better."

"What about work?"

"Cat will understand." Alex said. "If she doesn't I will make her."

"What about my Supergirl work?"

"The city will survive. You need a break."

"But-"

"No buts Kara, you are staying here where it is safe." Alex interrupted. Seeing how upset Kara looked Alex offered. "I will go to your place and get some of your things and we'll have a sisters' night here."

"Really?"

"Really." Alex smiled.
