Emma looked out the glass window and already found ten Cadmus agents converging on Kara's location. She realized Kara was a priority target, but did not expect to get attacked so soon. The alarms had only just gone off.

Kara struggled to unhook all of the medical equipment from her body. Emma saw this, and didn't know what to do. She had to fend off the oncoming agents, but Kara looked like she was stuck. Eventually, she decided on a course of action.

"Kara, work on unhooking yourself. I'll get rid of the agents." She quickly took off her doctor's coat to reveal a tactical suit inside.

Right as she finished un-holstering her gun, the Cadmus agents burst through the door. She immediately shot down four of them, but the other six converged too quickly on her. She couldn't shoot all of them, they were too close.

She could hear Kara shout her name, but did her best to tune her out. Emma focused solely on her opponents, and her extensive training took charge. She turned her gun around, and smashed the butt of the weapon into one of the other agent's heads. He was down.

Five to go.

She swiftly kneed one of her other attackers in the stomach, and then elbowed him in the mouth, effectively knocking him out. Agent Rose then turned to another attacker and performed a complex Judo throw, successfully incapacitating him and breaking his arm in the process.

Three left.

She ducked under a punch from one of three remaining agents, and kicked his legs out from under. He flailed and knocked over the agent next to him. While they were both dazed, she turned to find her last attacker and came up empty. She couldn't find him.

That could only mean one thing.

Emma whirled around in fear for Kara, only to find the last agent's gun right in her face. As his finger moved to squeeze the trigger, a blur shot across the room and slammed him into a wall. He immediately crumpled and fell to the ground unconscious.

Emma took one second to look at Kara in gratitude, before turning around and finishing off the two dazed agents she had left behind.

Kara ran over to her and hugged her. "I'm so glad you're okay. You really weren't lying when you said you were a badass."

Emma laughed. "Thanks for saving me back there." Kara smiled. "Hey, I'm not the one who took down nine agents by myself."

They basked in their nice little moment before they saw three different aliens approaching. Kara flashed Emma a wide grin. "Looks like we're up."

Emma nodded, eyes hardening once again, ready. "Right behind you."

As soon as the aliens got close, Kara and Emma split off. Emma ran to the extra gun stash they had in the corner of the room, and Kara flew into the fight head on. Seeing Kara fearlessly throw herself into the fight emboldened Emma and she ran harder until she slid down next to the hidden armory.

Kara slammed her fist into the head of a White Martian, dizzying it slightly, while she turned and kicked the K'hund behind her. The third alien, one she had never seen before, snuck up on her while she was occupied with the other two, and smashed her into a wall.

She crumpled to the floor, surprised at the power of this third alien, and reeling from the pain. She stood, dusting herself off, and sped back into the fight. Other DEO agents were arriving with reinforcements, but there was not much they could do against the aliens.

Emma could see Kara struggling to fight all three off at once, and grabbed the closest gun she could see. She immediately aimed and shot, desperate to do anything to help her friend. The blast sent the unidentified alien flying across the room, and it fell unconscious.

Kara tackled down the K'hund, but the White Martian snuck up on the duo and smashed into the Kryptonian. She was sent skidding across the floor, and laid there dazed.

That's when she looked up and saw a flash of green.

J'onn.

He rammed into the White Martian, simultaneously yelling at the other agents to help Alex in the prison hold. Kara thought about Alex and how she was right in the thick of the fight, and left J'onn to handle the Martian. With only the K'hund to fight and no other distractions, she easily smashed into it and sent it through the wall.

Kara motioned for Emma to follow her, so she took as many guns as she could and they both left. Kara led them in the direction of the prison hold, until she abruptly stopped. She fell to her knees, green coursing through her veins.

Emma immediately ran to her side, concerned for her friend. They both looked up to see Lillian holding some kind of device, accompanied by roughly twenty agents. They all had Kryptonite guns trained on Kara.

Lillian laughed maniacally, ready to end this once and for all. "So we meet again, Supergirl. Glad to see you're doing well."

Kara spat in her direction. "You won't get away with this, Lillian." She looked towards the evil blonde, and all she got in return was a smirk. "It's too late, girl. I already have. I've already won, Kara. The exodus ship is just miles out, already loaded with as many aliens as we could find. Once we get you and the prisoners secured, it's over."

Lillian laughed as she watched some of the hope deflate from Kara's eyes. "It's finally time, girl. Your time on this planet is up." She pushed a button on her kryptonite device, and Kara let out an ear-splitting scream, immediately falling to the floor and writhing in pain.

Emma couldn't watch this.

She did the only thing she could think of and trained her gun on Lillian. "Lillian, stop this. Put that down, now. Or I'll shoot."

Lillian just laughed. "I'm not entirely sure who you are, or who you think you are. But if you care to look around, all of my agents are armed to the teeth and ready to shoot on my command. You're highly outnumbered. If you so much as even move, you're dead."

Emma bit her lip, realizing her predicament, but she couldn't stand to see Kara screaming in pain on the floor. Tears came to her eyes, and ultimately decided she needed to stop Lillian at all costs. She looked up, aimed her gun, and shot.

Lillian screamed as she was unexpectedly hit with a bullet in the leg. Upon getting injured, she turned tail and immediately headed for the exit. Emma fully expected to get shot, but she felt no bullets. She looked up tentatively, only to find Jeremiah, Alex, and other DEO agents fighting off and distracting the remaining Cadmus agents.

With chaos happening all around, she stayed low to avoid bullets. She crawled on the floor until she finally reached Kara, panting and sweating on the floor. Her veins were still alight with green, but she seemed to be in less pain than before.

Emma turned her on her back and grabbed her friend's hand. "Kara, listen to me. Lillian's gone, the kryptonite will wear off soon. Just stay with me, okay?" Kara gave a weak nod.

She looked up at her friend's warm brown eyes and gently smacked her arm. "That was so stupid."

Emma gave her a teary grin and stayed with her, until she looked around to see no remaining Cadmus agents left. Alex looked around to survey the room, and her eyes immediately landed on her pained sister, struggling on the floor. She also saw another agent on the floor beside Kara, but decided to ignore her for the time being.

Upon seeing her injured sister, she immediately began running towards the two girls. She almost made it when an opposing agent snuck up behind her and shot her in the left thigh.

She immediately fell to the floor, searing agony spreading throughout her body and couldn't move. Jeremiah screamed out his daughter's name, before turning to the agent and slamming his metal fist into his stomach.

Kara heard her sister moaning in pain, and immediately turned to see what had happened. She had been too distracted by her own pain to notice anything, but as it subsided, she grew more concerned for her sister.

She got up to her hands and knees and began making her way over to her fallen sister, who was profusely bleeding arterial blood onto the floor. The bullet must have landed and hit her femoral artery.

Kara finally made the grueling and painful journey over to Alex, before noticing something was missing.

Someone was missing.

Emma.

She turned around, fearful of what she would find.

And there stood Lillian, balancing almost all her weight on her good leg, holding a gun to Emma's head.
