Yaaaaaaaay 12 followers! I'm slightly surprised that I have this many followers for such a particular type of crossover, but nonetheless I'm glad you guys love it! Now on with the story! :D

The Doctor dashed down the hallways in great haste, searching everywhere for a place to hide.

I'm sorry Shawn, I am so sorry…He thought in anguish. His hearts beat wildly as he rounded corners and ran as fast as his legs could take him to the maintenance door that sat in the back of a hallway. Not wasting another minute he unlocked the door and went in, sonicing it behind him.

He slouched down on the back wall and caught his breath, running a hand through his hair he contemplated the situation. Oh how he wished these things would never happen to him, if only everything could be fine and perfect in the universe. He had lost so many friends and companions in his lifetime, so many that sometimes he felt like giving up and keeping to himself to make sure that all those he loved and cared for were safe, but he lost them all anyway. This thought of pity and shame was soon turned to deep anger and determination.

No more, He thought, I will defend Shawn with my life; he will not die because I failed to save him from this.

The thought burned in his mind as he soon found himself pacing around the room in deep thought. Okay, Shawn's been possessed by an evil mastermind, you're stuck in the maintenance closet with Icarus' brute squad searching for you, and he's got at least twenty other prisoners that are currently sedated and in holding chambers…

He paced around faster and faster until he got to the point where he was practically running around the room as his thoughts and worries sped up with his legs. Soon slowing down he came to a dead end in his mind.

He groaned, "If only I could-"

He was interrupted by a gentle rattle that sounded from behind a box filled with cleaners and a faint breeze coming from behind.

"Of course! Oh, I am so thick!" He moved the heavy box to the side revealing a good-sized air vent. "Alright, find Icarus, stop his plan to dominate the world, and save Shawn along with half a dozen other people. What could possibly go wrong…?"

"Note to self, never say 'what could possibly go wrong' ever again."

The Doctor mumbled to himself as he made his way across the tunnels in the ventilation system at an impossibly slow pace. It had been roughly an hour of crawling in the slowly rising temperatures of the shafts. He just hoped that his rough idea of the facility and the air tunnels would help him find Shawn soon and possibly come up with another brilliant idea on how to get Icarus out of his friend's mind.

He sighed and stopped to give his aching knees a rest and wipe the sweat from his brow as he slumped against the wall and let the hot air pass through. How many times have I been in this situation before?

He heard a shuffle come from around the corner to his right and a few low, quiet, gasping breaths. Making nearly no sound, the Doctor held his breath and slowly crept forward, not daring to speak. He tensed, blood pounding in his ears, as he prepared to flee at any moment in full awareness that it could be one of Icarus' puppets come to catch him. The shuffling grew louder as whomever it belonged to came closer, the Doctor reached for his screwdriver. Suddenly, a figure leaped around the corner and punched the frightened Time Lord in the nose. The Doctor grabbed it and shouted a few curses as he tried to soothe it.

"Oh my god! Are you okay? I thought you were one of them."

As the Doctor's vision cleared from the pain, he saw a light blue-haired girl with long arms crawl over to him.

"Yep, I'm fine," he said through clenched teeth and let go of his nose. No blood, good. "But seriously of all things to do you'd punch them in the face?"

She shrugged her shoulders, "Seemed logical to me, here let me see it." She inched forward.

"Nope, no it's fine." The Doctor backed away and slumped back onto the wall, catching his breath. "How did you know I wasn't one of Icarus' guards?"

"If you were, you would have easily deflected the punch and taken me. Most of Icarus' thugs are skilled fighters…which kind of makes sense if you start to think about it…"

"What's your name?"

"People call me Nancy." She sat back and flipped her hair out of her eyes.

"Nice to meet you Nancy, I'm the Doctor." They shook hands and exchanged friendly smiles as he continued, "So…how did you get here?"

She sighed and said, "Long story short, I work for some…agencies and they asked me to take a look down here because they were suspicious. I got caught by the psychopath and he put me under sedation. By the time I woke up, the room was empty and I made my escape through the air vents. What about you?"

"Oh, my friend and I were just traveling, got jumped in the streets, woke up in the main facility, met Icarus and made my escape."

Nancy looked behind the Doctor expectantly, saying, "So where's your friend?"

The Doctor's face fell, "He's been possessed, I'm going to find him." He crawled past the contemplating Nancy and made his way to another opening with her following behind.

"But you can't!" Nancy shuffled after him. "Once one's been taken over there's pretty much no chance of coming back. Not to mention Icarus' guards are all over the place. You go out now and you'll be surrounded in seconds."

"Hush." The Doctor said in a soft whisper as he came to a grate that revealed a bird's-eye view into the main facility below where he was with Shawn not an hour ago. He leaned over and peered in, guards were stationed by all of the entrances and exits. He moved a little to the right to get a better look at the prisoners and gave a quiet sigh of relief, Icarus hadn't done anything to them…yet.

"What's in th-" Nancy's question was interrupted as Shawn's voice called through one of the speakers in the room.

"Ooohh Doctor?" His voice seemed slightly malicious through the intercom, "I'm getting tired of playing hide and seek, why don't you come out along with the other brat who's hiding? Maybe we could share a smoothie and have a little chat."

Nancy and the Doctor exchanged surprised looks.

"Oh yes," He continued, "I'm not such an idiot to not know that both of you are up to no good. It doesn't take a genius to know that you two have found each other already and are planning to stop me. So meet me in the main facility where we left off and no one will get hurt. You have ten minutes, or else…and here's the best part," He chuckled maniacally as if a funny thought occurred to him, "I'll torture Shawn until he begs me for his death. So come with the girl, and we'll make an arrangement."

They heard the faint click of the intercom being turned off. The two sat in silence for a few seconds, running over the message in their minds one more time.

"I have to go." The Doctor said in a low voice.

Nancy's eyes widened and she hissed, "But you can't, we'll be killed on the spot, at best!"

"Yeah, but if I don't, my friend will go through something that no human being should ever have to go through, and it will all happen because of me." He paused and said more to himself than to Nancy, "And I don't think I could live with that."

"Do you think that he will actually let Shawn go if you just agree to his terms?" She scoffed, sitting dumbfounded that he was making that decision. "I know your very attached to your friend, but since he has little chance of coming out of this unscathed or even dead, doesn't mean that you need to get yourself killed or possessed."

"There's a small chance…" The Doctor hesitated, "And that's the only chance I've got." He looked back at Nancy to see her face light up slowly with a small grin.

"Oh Doctor, that's it!" Nancy exclaimed with suppressed excitement, "I have a plan that'll give us a chance…" She scooted forward a few inches, "And I believe it's the only chance we've got."
