Chapter 1- The Odd Couples
"Remind me...how we got stuck with the most boring assignment ever," Mara whined to her partner Cami as she absent-mindedly ran her fingers along the solid oak handrail lining the old train's corridor.
"Seriously? Mara, we just graduated from the academy. What did you expect?" Cami said, annoyed that her partner couldn't ever just be content.
As the two Aurors walked the length of the train, young witches and wizards hurried past them in both directions, yelling and laughing. It wasn't that Mara didn't like kids or anything. But one of the main reasons she'd become an Auror was because it was usually fast-paced. There was nothing fast-paced about security duty on the Hogwarts Express.
"So how long before we get to the school?" Cami asked her partner.
Mara looked down at the silver and black leather watch strapped to her left wrist. "Another hour."
Cami glanced out the window. The sun was just disappearing over the horizon, leaving a tiny sliver of orange along the skyline which meant it had finally gotten dark enough that the golden lamps on the inside of the train finally flickered on.
"Well at least we got to take another start-of-term train ride," Mara said and peeked into a nearby compartment where a group of boys and girls sat talking animatedly and occasionally laughing. It brought back memories of her and her best friend at Hogwarts Trisha. They'd planned on being best friend for the rest of their lives. But then Trisha had been recruited by the Montrose Magpies and Mara joined the Auror academy. The two friends had barely spoken in the past two years.
Without warning, the train came to a complete stop. Mara's flashbacks crumbled, and the jerk of Newton's second law of motion took effect, pulling Mara and Cami face-first into the floor. "OUCH!" Cami groaned. All of the lamps went out at once, leaving a half-moon as the only source of light.
Cami rolled over, ignoring the dull ache pounding through her hands and knees and head. (Each body part that had made contact with the ground.) Just as Mara and Cami were getting to their feet, a blood-curdling scream sounded from the front of the train. Cami's stomach dropped. She whipped out her wand, noticing that Mara had done the same just a split second before. Students who'd been out in the corridor fumbled in the dark to get inside a compartment as the pair sprinted in the direction of the scream.
When they'd reached the front of the train, the women looked around, peeking in a few of the compartments, trying to find a panic-stricken teenager. A sudden thud sounded behind the door of the train's cab. Before Mara and Cami could turn around, a man crashed through the closed door, landing just a few inches short of a very surprised Mara.
What the bloody hell?! Mara's thoughts screamed. Her adrenaline was pumping hard, and she couldn't decide whether she was more panicked or excited that this assignment had suddenly become a hundred times less boring.
Without hesitating, the man who'd crashed through the door jumped up and rushed back into the train's cab. Mara followed him with Cami at her heels.
Inside the two women came upon a scene that neither of them could have ever prepared for. It took a second for both of the young Aurors to register what was going on. Under the dim emergency lights, two men were circling a livid Professor Patil.
Against the far wall, Professor Flitwick lay unconscious on the ground. Cami's immediate response was to tend to the victim; she ran the perimeter of the room, never turning her back on the three figures in the center.
To Cami's and Mara's horror, Professor Patil opened her mouth and gnashed a mouthful of enormous teeth. She hissed and a forked tongue at least a half a meter long emerged from between her gasped out loud, and Cami froze momentarily.
That's not right. Mara thought. I've never seen anything like it.
Mara, the top of her class both at Hogwarts and at the academy, mentally searched through all of the creatures filed away in her brain but came up with nothing. Her gut wrenched as she realized that she had no idea what to do. They'd trained her for battle with every creature known in the wizarding world. But what about the creatures that nobody knew about?
Suddenly, the taller of the two men pulled out a water gun. A water gun? Mara watched curiously as the liquid from the gun hit the creature that looked like the Hogwarts transfiguration master.
"Now Dean!" the tall man shouted. The shorter man burst forward and dumped a bottle of the same unknown liquid over the sizzling creature, whose skin began to boil and slough off. Every drop of the liquid acted like acid on the creatures skin.
"Alright. Off with his head!" The shorter man yelled.
His teammate reached into his jacket. "Dammit!" The tall man cursed, "Where's the knife? It's not here." His eyes began searching the floor. But as each second passed, the creature began healing itself, and it grabbed at the shorter man.
Mara shot a glance over at Cami, who was watching the scene while also tending to the unconscious professor.
Unsure of what to do, Mara shot a blast from her wand at the creature. "Reducto!" It went sailing into the corner of the room and out-of-reach of the two men.
"What the hell!?" the short man whipped around. He and the taller man stared at Mara in shock. "Who are you?!"
Mara kept her eyes on the creature. She didn't even bother looking at the men. "Does that really matter right now?"
The Professor Patil monster jumped to its feet and sprang at Mara. Mara ducked, but the move was unnecessary. "Avada Kadavra" A green light erupted in the room and the monster was blasted into the opposite corner.
Cami had deemed Professor Flitwick in stable condition, though he was still unconscious, and she stood to join the fight. Mara looked behind her. "What in the -?" she couldn't even finish the thought as she realized that Cami's killing curse hadn't even harmed the creature.
Cami realized it too. Oh...this is Bad!
Mara yelled at the men, "Whatever you poured on it before...do you have more?"
The shorter man stopped gawking at the two women and focused on the creature once again. "I'm out. Sam? You?"
"I have one more bottle." He held up a black squirt bottle for the group to see. "But we still don't have the knife."
"We can take care of that," Cami assured them rubbing her free hand on the back of her neck.
Mara caught the signal. "Just throw the bloody liquid at it."
And that's exactly what the man did. He ripped the cap off the squirt bottle and threw the contents at the creature. It shrieked as the liquid burned gaping red holes in its skin.
Cami had stepped up beside Mara, and they both raised their wands at the creature. "Diffindo!" they shouted in unison. The monster stopped moving, and its body collapsed as the head rolled a few feet in the direction of the two women.
The two strange man stared up at Cami and Mara, each coming up with his own theory on what they'd just watched these two girls do. Then the two women turned their wands on the men.
"Who are you and what are you doing on this train?" Mara demanded.
The men looked at Mara and Cami in surprise, then at the wands, then at each other, then back at the wands.
Short on patience and extremely overwhelmed by the terror she'd just experienced, Mara blasted a warning shot from her wand at the lamp on the wall behind the men. The lamp exploded, sending bits of gold and glass across the room. "I am ordering you. Answer my question." She glared at the boys.
"I'd suggest you do as she say." Cami's voice chimed in calmly. Cami wasn't a huge fan of Mara's violent methods, but this was not the time to argue over methods...again. It was already taking every last bit of energy that Cami possessed to keep from freaking out. She had not prepared herself mentally for so much excitement on this assignment.
"Alright. Everyone just hold on for a second," the tall man held up his hands in surrender.
"Yeah! Hold on! Because I'm wondering what fucked up universe we just stepped into?" The other man said as he grabbed the handle of a pistol in the back of his jeans. His theory was that these girls were just another type of demon trying to get ahead, and he would kill them in a heartbeat if they threatened him.
"Shut up Dean," the taller man barked. Dean held up his free hand in defense. Then the taller man twisted back to Mara and Cami. "Seriously though. We're not the bad guys. We're hunting the bad guys." His theory was much less cynical; he figured that these girls were just hunters with a unique set of weaponry.
Mara took a step forward, and Dean pulled his gun.
"Expelliarmus!" Mara yelled. The gun went sailing across the room.
Mara smiled. That was fun. "Now, from your partner here, I've gathered that your name is Dean. Dean what?"
Dean refused to speak. In fact he wouldn't even look at Mara, he just stared at his gun, lying on the floor near the creature's dead body.
"Winchester," the tall man answered for him, "He's Dean Winchester and I'm his brother Sam."
"Well, Sam and Dean-" Mara started but was interrupted by the soft chime of her cell phone ringing. She answered without checking the caller I.D.
"Yes?" she answered, making sure to keep her wand aimed at Dean.
Mara listened to the Head of Aurors on the other end ask her about the distress call they'd gotten when the train had suddenly lost power.
"We have the situation under control now Mr. Potter. However, Professor Flitwick was injured and possibly some students, nothing serious. But there is a situation. We will need to have you get someone to get this train moving again from the London station, and we also request that two more Aurors meet us at the school to ensure the safety of the students as they proceed from the Hogwarts Express to the school. Cami and I will need to take care of a few things yet on the train."
Mr. Potter agreed to all of Mara's requests, and then ordered her and Cami report to him the moment they returned to the Ministry.
"Yes sir of course. We will head straight there as soon as we're finished."
Mara hung up and pocketed the small phone.
"Mara," Cami caught her partner's attention, "We should get these men confined."
Mara nodded and moved behind Dean, jabbing her wand into his back.
"Ow!" he complained.
Cami did the same to Sam, but without the physical abuse.
The witches prodded the men along until they found their compartment. Fortunately, it was also near the front of the train. As soon as they were all inside, Mara locked the door and made sure there were no gaps in the curtains.
"Okay. This is ridiculous." Dean cried out in exasperation. "Look ladies. We're hunters. We hunt evil creatures, so unless you're supernatural beings that hurt people, which so far I'm not convinced you aren't, then we're no threat to you."
"And we should believe you because?" Mara challenged.
"Well let's start with because we just helped you kill that thing back there and probably save an entire train full of people," Dean said in annoyance.
Mara frowned, keeping her wand pointed squarely at his chest. "Fine," she admitted, "Maybe you did. But you're still strangers...on a train full of children. So I'll apologize for not being more hospitable."
Cami focused on the man she had at wand-point, hoping that he would be more level-headed than his brother. "Okay then. Sam? You're hunters. So what exactly are you hunting?"
"They're called Leviathans."
"That's not possible. They don't exist," Cami stated matter-of-factly. And she should know, she'd read countless books where Leviathans were mentioned. But none of them contained any creatures that actually existed in this world.
"You'd be surprised at all the creatures out there you thought were only fairy tales or ghost stories." Though Sam had a feeling that these two girls actually did have a good idea about many of the monsters and demons that inhabited this planet.
"Oh you really have no idea how much we'd believe." Cami smirked confirming Sam's suspicions. Cami was baffled by the men. They're speaking as though they... "Oh gosh. You guys have no idea where you are do you?"
Dean sank down onto the bench. "Yeah. We're on a train."
Mara raised an eyebrow, catching on to Cami's train of thought. (No pun intended). Wow! These two are in way over there heads.
"Technically yeah, but-" Cami cut off as the train lurched forward, moving again and the lamps in the compartment flicked back on.
Cami and Mara both lost their balance as the train suddenly picked up speed. Cami went sprawling across the floor between the benches, much the way she had in the corridor earlier.
Mara's fall proved much worse. The young Auror fell forward right onto Dean.
Her knee collided with the bench between Dean's legs, and her ankle twisted just the wrong way. Mara cried out in pain, holding back tears. Without really thinking, she grabbed hold of whatever she could, which in this case, was Dean Winchester. After a few seconds, the pain seemed a tad bit more bearable, and Mara realized where her grip was. She sprung back off of Dean, disgusted with herself. Dean, on the other hand, sported a smug grin.
Sam helped Cami into an upright position and picked up her wand for her. Dean also had a wand in his hands...Mara's wand. The women eyed the men nervously.
After a few seconds of tense silence, Sam carefully handed Cami her wand. He nudged Dean, and Dean reluctantly handed Mara's wand back to her. Sam didn't feel the need to make anymore enemies, and by returning the girls' weapons, he thought that maybe the women would start trusting them.
"Perhaps you could stop threatening us with those," Sam suggested to the women.
"Okay." Mara slowly lowered her wand. However, Cami didn't need to. As soon as Sam had returned her wand to her, she'd kept it at her side. Cami had already decided to try trusting the two Winchesters.
"Are those supposed to be wands?" Sam asked in amusement.
"No," Cami answered him, "They ARE wands."
"And before...you said Expelliarmus." Sam thought aloud.
"Yes," Cami nodded.
"What like the in Harry Potter?" Sam asked doubtfully.
"You're not just on any train. You're on the Hogwarts Express, a train full of witches and wizards."
Mara shot Cami a warning look. Unless in life-threatening circumstances, Aurors were not allowed to divulge information about the magical world to muggles.
Cami rolled her eyes. "What? They just killed a supernatural creature, and they knew what they were doing."
"Fine. But if anybody finds out, you're the one headed to Azkaban.
Dean shook his head. "Man! Why are all the hot ones crazy?!" he complained to himself. And he couldn't deny that the women were quite good-looking. Now that the lights were back on, Dean had noted to how each girl looked. The tall one, Cami, was full-figured with dirty-blonde hair, which she kept up in a ponytail, and pronounced facial features, including big blue eyes. And the short one, Mara, was slender, with long brown hair that had been curled and fell past her shoulders, and she had green eyes.
"But it's a story...a child's book. It's not possible," Sam feebly tried to reason.
"Something tells me you've seen more than one impossible thing in your lifetime," Cami smirked.
Mara collapsed on the bench across from the men, now drained from putting on a tough front and in a great deal of pain from the beating she'd took just moments before."Look, you guys can believe what you want, but don't say we didn't warn you. This place is real, and we are REAL witches."
Cami took a seat next to Mara, and the four sat there in silence. The sound of the train speeding over the tracks and the air rushing overtop the train had a very calming effect that allowed the group to sort out their thoughts.
"Okay. Fine. I'll go along with this." Sam finally broke the silence. "So what are you're plans now then?".
Mara put up a finger. She silently cast a Muffliato spell then turned to whisper in her partner's ear. Cami nodded, and whispered back.
After she'd lifted the silencing spell, Mara answered Sam's question. "Well, we have a problem. And since you two seem to know some things we don't, we'd like to see if we could work together. This is all circumstancial of course. We still have to report back to our superiors."
"And why would we help you?" Dean asked, though his words were much less harsh this time.
"Because if that really was a Leviathan in there. Then it is our responsibility to find and destroy any more that might be roaming around. If you're hunting them too, then we'd probably have more success working as a team."
"Sorry Lady," Dean said mildly, "But we don't play well with others."
"Well that's obvious." Mara said with a hint of amusement. "And my name is Mara, by the way. But admit it. If Cami and I hadn't showed up when we did, chances are one or both of you would have been lunch for that monster."
"And thanks for that," Sam cut in, "But my brothers actually right...in this case. We can't risk either of you, or anyone else, getting hurt under our watch. I don't think it will work."
Mara frowned because she didn't want to have to resort to threats, but it was protocol. "Fine, but either way we're taking you into the Ministry and turningyou over to the Head of the Auror Office. So it's up to you if you want to help or not?"
Dean jumped up, pulling yet another pistol from the inside of his coat.
"Impedimentia" Cami grumbled and flicked her wand, "Will you please stop with the crude weapon-wielding threats?"
Cami's curse blew Dean back into his seat with such force that the gun fell to the floor. Mara bent over and picked up the gun, unloading the bullets into one hand. Her eyes grew wide and her color faded. "You were going to shoot me!? With real bullets!?"
Dean didn't answer. He was too stunned as he realized that these women may actually be telling the truth, that they might actually be witches. Though the whole Harry Potter thing...that's taking it a bit too far.
"Look, you can't turn us in...to anyone. We have to stay off the radar," Sam urged Cami and Mara, "These Leviathans have people in high-places. The moment our names or faces resurface, they'll be on top of us like that." Sam slammed his hand against the wall.
Cami and Mara jumped.
"Then we'll make sure you stay hidden...if you agree to work with us." Cami folded her arms across her chest. She'd had even more time over the last few minutes to think about it. And if Mr. Potter did assign them to find more of these Leviathans, if that's what they really were. Then they needed these two men.
Sam understood all too well when he was being black-mailed. And though it was low, he and Dean couldn't risk being exposed. They'd come too far to get caught now. Besides, these girls might really make all the difference. Sam looked over at his brother. Dean didn't say a word which Sam knew meant that Dean couldn't think of a good enough argument.
"Fine," Sam conceded, "We'll try working together...for now."
A quick word to my reader's. I'd had this crossover swimming around in my head for awhile, and I think I wrote the first chapter over about four different times. More than anything right now, I need some feedback on what you think about this storyline so far. Can't wait to hear from you all. :)
