After work, Kara brought Clark out to see her Fortress of Serenity, just as she'd promised.

"Okay, your place is way cooler than mine." Clark said and Kara shrugged.

"What can I say, my parents didn't want me to hide in the Arctic all the time." Kara said, giving her cousin a hard time.

"I do not hide up at the fortress of Solitude." Clark said.

"Uh, it has the word Solitude in it. I think that means that you prefer to be alone." Kara said.

"Okay, are you done making fun of me Kara?" Clark asked.

"For now." Kara said as Kelex entered the room in the Fortress.

"Mistress Kara, who is this intruder?" Kelex asked, preparing to terminate Clark.

"Stand down Kelex. This is Kal-El, my cousin and the last son of the house of El." Kara said.

"Scanning to confirm identity." Kelex said as he scanned Clark and then quickly stood down.

"Identity confirmed. My apologies Lord Kal." Kelex said.

"It's fine Kelex." Clark asked.

"Oh Kelex, while you're here, I need you to access every single bit of data in both your memory and fortress's archives on the project Medusa and erase every last bit of it, nothing is to remain." Kara said.

"As you wish." Kelex said as he floated away.

"What's Medusa?" Clark asked.

"It's a virus my father created on Krypton as a defense protocol in case of invasion. The virus was designed so that an invaders would be wiped out while leaving the people and infrastructure unharmed. It's too dangerous a weapon to risk falling into the wrong hands." Kara said.

"You're right about that. I'll have Kelex at the Fortress of Solitude erase all the data on the virus from it's databanks as well." Clark said and Kara nodded, right as her phone rang.

"Hey Alex, what's up?" Kara asked.

"Winn has determined that Lena Luthor was not the mastermind behind the Venture explosion, she was the target. We're still working on determining who is behind it, but you and Clark need to keep an eye on her until we find out." Alex said.

"We're on it." Kara said as she hung up and looked at Clark, who nodded as they flew out of the fortress.


"Should be a smooth flight, Ms. Luthor." the pilot said to Lena as they got in a chopper and Lena was honestly counting down the seconds until Corben tried to kill her again.

"I hate flying. I know statistically, it's the safest way to travel, but still," Lena said as the drones appeared and set their sights on them. "What the hell?"

Right as the drones open fired, Supergirl and Superman appeared right in front of the chopper, blocking the bullets.

"I thought you two might show up. You spoil all the fun." A voice said from the drones.

"You know, if you were expecting us to show up, you really should've brought something a little more powerful." Superman said.

"I did. I brought my wits. I've drones planted throughout the city, targeting civilian populations as we speak. Your choice, aliens. Innocent civilians or the chopper?" the voice said.

"Go. I got the chopper." Supergirl said to Superman, who nodded as he flew off.

The drones began circling the chopper, though Supergirl blasted them as fast as she could trying to protect the chopper until fired a missile at her, just like he did before, but this time, rather than putting herself in between the missile as a human shield, Supergirl simply used her freeze breath to slow the missile down and cause it to fall harmlessly out of the sky before she used her super strength to ram through the last drone and destroyed it before helping land the chopper.

"You're safe now." Supergirl said as he looked inside the chopper.

"What the hell was that?" Lena asked.

"Someone's trying to kill you." Supergirl said bluntly and Lena didn't even seem to look surprised by that.
