Author's Note:

Hey guys, this isn't the usual RangerOfOlympus, but a close colleague. I'm not a very experienced writer and this is my first piece, so I hope you like it! Give me as much advice for the future as you can. This is for fans of Doctor Who, Supergirl, and of course, PJO!

Publisher's Note:

Hello, dear readers! If this is the first fanfiction you've read that I've written/published, shame on you! You will be very confused during a couple parts of this because it takes place after a few other fanfictions. For example: "Truth be Told" and "Heroes of the Past, Villains of Today." If you follow me, there will be references to the latter in here.

This was actually written by a close friend of mine, but they didn't have a FanFiction account. Please try to contain yourselves if you don't like it. I mean, I'm sure you will like it, it's pretty good, but just in case...Oh, one more thing. I haven't actually written a fanfiction where Doctor Who met PJO, but I read one like that so...yeah. Just read and review. I'm probably boring you.

Kara's POV

It was a normal day at CatCo, and I was sitting in my quiet cubicle outside Cat Grant's spacious office. Winn was busily clicking away at his computer. It was early and Miss Grant's coffee was waiting on my desk, still steaming.

I heard a soft buzzing in my ear. As I shut my eyes, I heard the snide voice of Miss Grant in the elevator. Every week, she had a new rude comment about her elevator.

"This elevator smells like...common people. Ugh. Why should I pay for a private elevator when it smells exactly like every other elevator in the building?" she commented, annoyed.

I stood up, drawing Winn's eyes from his computer. "She's here." Everyone stood, brushing themselves off.

James Olsen took a step in my direction, making my heart beat faster. I quickly pushed my glasses farther up my nose and smoothed my hair. I could already feel my cheeks flushing.

Cat stood in the open space between the elevator doors coyly. As her eyes roved the silent room, I picked up her coffee and began to carry it to her. She sized me up, and snatching her coffee sniffed disapprovingly.

Please like it, please like it. That coffee cost me eight bucks! I prayed. Out loud, I said awkwardly, "National City's finest."

Cat glared at me, as always. She strode to her desk, the sharp clicks from her heels muffled by the thick carpeting. As she continued on to her desk, she dropped the coffee in the trash bin.

The new employee, Harmony, stood waiting for Miss Grant in front of her desk.

"Oh, Harmony," Cat spoke derogatively. But, that was no surprise. "What do you want?"

Harmony had only just begun to reply when the elevator doors dinged open once more. A boy about eighteen years old charged out. The teenager had black hair, sea-green eyes, and was wearing jeans with a faded orange shirt. He held a bronze sword about three feet long that seemed to be...glowing?

"Die, foul beast!" he shouted as he dashed into Miss Grant's office.

As the boy leaped, he swung his sword, literally cutting Harmony in two. Before I could react, the boy jumped out of Miss Grant's and fell to the concrete. Just before he hit the ground, I could've sworn I saw a streak of black swoop beneath him and carry him away.

Miss. Grant called,"Kira!" I rolled my eyes. Would she never learn my real name? "One of my employees was just stabbed in the leg, and I want to know why!' Miss Grant announced.

"What? Kn-knife? Leg?" I asked, my head spinning.

"Yes, you incompetent moron," Miss Grant replied. "Do you not have eyes?"

"Of-of course I do, Miss Grant. I was just confused, Miss Grant. Right away, Miss Grant."

"Stop blabbering and get to work!" she commanded.

"Kara?" James asked me nervously.

"Roof. Now," I said in an undertone.

James, Winn, and I stood together on the roof. James had his ever present camera and Winn was just staring at me with a blank expression on his face.

"Did you not see what happened?" I said incredulously.

"What?" Winn asked. "Harmony getting stabbed in the leg?"

"No, her getting chopped in half like a pineapple," I exclaimed loudly. Now I was just getting frustrated. Our conversation was interrupted by a noisy mechanical whooshing, making my hair blow out of its ponytail.

"Ummm," James mumbled very eloquently.

"Kara," Winn said slowly, looking behind himself, "You may want to look at this."

"Kara," James stated commandingly. Finally I glanced up. I saw a blue box, like the old style police ones. It was normal except… it was flying. Right at us. With a boom the box landed on the nearby helipad.

"What is that?" Winn asked quizzically .

James raised his camera tentatively and I heard a snap as the camera took a picture. I stood unmoving, a creak the doors on the front side opened and a man peeked out. He had brown hair, and wore converse as well as a brown trenchcoat.

"What year is it?" he asked in a British accent. I was surprised by the question.

"Sorry?"James clarified.

"The year," the man demanded impatiently.

"Uhh, 2017," I stammered. Winn ran his fingers along the side of the box.

"Stop touching my TARDIS," the man growled. Winn quickly drew back his hand.

"Did you say TARDIS?" James asked. "Who are you?"

"I," the man started impressively, "Am the Oncoming Storm, Destroyer of the Daleks, The Last Timelord. I am...the Doctor."

"Ugh," a disgusted voice groaned from behind me. "It's you again."

I turned and saw the boy who had killed Harmony astride a pure black horse with…were those wings? The teen was still holding his bronze sword out in front of him.

"You," I growled. My friends were watching him too. "You monster! Harmony is dead because of you!"

"How'd he get that horse up on the roof?" James wondered.

"Can you not see the wings?" I demanded.

"Uh…,"

"She was a monster!" the boy yelled gesturing down to where he had jumped out of the window.

"Monsters don't exist. Aliens on the other hand…" I trailed off.

The doctor looked at me appreciatively and nodded, "Aliens are everywhere. Like me; I'm an alien."

"You're an alien?" I asked incredulously.

"Yes…" the doctor said as if the statement was unimportant.

"Two aliens. On one roof? This is crazy."

"Who's the other one?" the boy asked. I rolled my eyes and neglected to answer his question.

"Is everyone an alien here?" the doctor faced me. I highly doubted the teenage murderer was an alien, so I gave him one of those looks that conveys entire paragraphs. This particular look was something along the lines of:

This teenager seems out of his mind. I don't believe he has either the capacity or the brains to be an alien, like us. The doctor seemed to sympathize.

"Not everything is an alien!" the teenager growled under his breath. "We covered this at Camp Half Blood," he finished glancing at the Doctor. I didn't bother to ask what the camp he had mentioned was.

All I needed to understand was that these two had met before.
