Warning Now, Before you read: Severus's appearance will change - mainly in ethnicity. If you want the FULL reason why, please see the author's note # 5 at the bottom of the chapter. Thank you. :)

"Hey, did you guys hear?"

The golden trio turned to see a young Gryffindor with an excited gleam in his eyes.

"No, what?" Harry asked curiously.

"Someone - that Collins kid, I think his name is - is going to pull a prank on Professor Snape, right in the middle of the Great Hall!"

"What?" All three of them gasped; Hermione from shock, Ron from excitment, and Harry from a combination of the two.

"When?"

"Today, during breakfast."

Apparently they weren't the only ones to know about this, as all four suddenly noticed a stampede of students making their way to the Great Hall, whispering and giggling to each other.

Not wanting to miss out, except for Hermione who was less-than-amused by this, they too ran to breakfast.

Sitting down by their friends, while stilling keeping a side-eye on the teachers' table and Professor Snape, they began speaking in hushed tones.

"What's going on with this prank, does anyone know," Harry asked the group.

"N-not really," Neville had a slight tremble in is voice, probably fearing what Professor Snape would do to the prankster, or anyone else in his house. "I just know that Tom Collins (1) is the one who said he was going to do it."

Hermione decided to question him as well, "What exactly is he going to be doing? He does know that no one has ever been able to sucessfully prank Professor Snape before, right? How does he expect to accomplish this?"

"Wait!" Ron interjected, "Tom Collins, as in 'Tom he-who-is-convinced-that-Snape-is-harboring-a-vampire-in-his-room Collins', is behind this."

"Um, I guess so... And I don't know Hermione, he really didn't us give any details."

Tom Collins is a Gryffindor seventh year who for years has been convinced that Snape had a vampire in his rooms, ever since he was a fourth year and was down in the dungeons past curfew, apparently hearing odd noises coming from Snape's rooms, and then 'a flash of black so quick that it was like a snitch on caffine, but the size of a person' as he put it. Everyone else thought that it was more convincing that Snape was a vampire, or that an actual vampire would be too afraid of Snape to want to be his roomie. Collins was still convinced that he saw a vampire though; everyone wondered what affect that would have on his prank.

In a silent whisper came the spell "Veniecum Sanguinous", (2) as the speaker cut open his own palm - hidden from view under the table. He waited. He would wait for two minutes, if it did not come then he'd have to go through with the dangerous part of his 'prank'.

Even though two minutes went by and there was still no sign of it, there was an air of damp-suspision, or something dark in the air. The castor grinned, it'll come for this one. He knew it would.

This time the spell could not be called out in a whisper, so the young man abruptly stood up, pointed his wand towards the teachers' table and yelled "Morsa Moris - Vam!"(3)

A deadly streak of gold flew across the room, right at Professor Snape, who barely had enough time to widen his eyes in fear as it made its way towards him.

The potions teacher barely registered the fact that someone called out 'Severus'...

Before he found himself on the ground, across the room, with another body shielded over him.

He looked up and into the other's eyes.

"Klaus..."

Everyone else in the Great Hall was in an uproar - panic throughout all four houses, afraid that either Collins had killed Professor Snape, or that he would come for them next.

Several of the teachers sprang into action after Collins unleashed the spell, casting a body bind on his triumphant looking figure.

For anyone looking directly at Severus Snape, they would see an odd flicker in his appearance every few seconds. Although who would really notice that when the odd being over said Professor was currently way too close into his personal space, lips almost touching.

The mysterious man bypassed the lips and went straight to the neck, fangs extending out of his mouth and lightly into Snape's pale neck. The potions professor gasped, but then calmed half a second later - looking as if he had just taken an extra strong calming drought. He sighed, eyes half lidded and whispered something that people further away were unable to hear. The (now obvious) vampire withdrew his fangs and licked the two little bite wounds that were left there.

He smiled and leaned in again, this time brushing his lips against Snapes... and finally sent the glamor spell, or whatever spell Snape had on him, on a seizure-like flicking spree. The vampire kissed him once more, and suddenly the flicker burned out; a slightly different looking Severus Snape was in its place.

He still had the same features - black hair, dark brown eyes, pale skin - except that instead of looking completely caucasian(4) he now looked mixed with something, possibly something asian. His eyes had a slight squint to them, his face wasn't as sharp, he looked as if he had gotten shorter (although it was hard to tell since he was still on the ground, being held by a vampire), and his nose wasn't big anymore - it was still slightly hooked, but it looked more like a random bump then generally being hooked though. Lastly, he looked younger too, which was odd. (5)

The vampire stroked the side of his face gently, then wrapped an arm around his waist and pulled him up with him. Snape leaned his head on the vampire's shoulder, who in turn smiled softly at him. The vampire then looked into the crowd and glared at Collins with dark, glowing red eyes.

"You best mind your own, damn business next time. Try that again," The vampire flashed his fangs, "and I'll make sure any punishment your teachers give you will be a tickle compared to what I'll do".

Collins couldn't nod because of the body bind, but the look in his eyes made it clear that he wouldn't try anything again.

The rest of the students gulped.

Dumbledore chose this moment to end the 'show' and ordered all heads of house to take their students back to their common rooms until further notice. After, he and Madam Pomfrey took Snape and the vampire away, most likely to the Hospital Wing to make sure Professor Snape was okay.

The Gryffindor common room was surprisingly silent for a while, until Ron decided it was time to break it.

"So, I guess Collins was right then, eh? Scary."

Harry and Hermione nodded in agreement. The Boy Who Lived then thought of something and turned to Hermione.

"What was that spell he shouted before? Collins I mean... It wasn't an unforgivable."

"No, it wasn't. Or at least, not really to wizards. 'Morsa Moris - Vam' is a curse used as a challenge to a vampire; the challenger will use it to harm a vampire's mate-"

Ron gaged, recalling how the vampire had his lips all over the professor.

"The curse can greatly harm a vampire mate, and even kill the mate if they are human - wizard or not. It's only legal because although the curse harms the mate, it's actual intention is towards the vampire. Nothing is more upsetting to a vampire then something happening to its mate, so putting its mate's life in danger forces the vampire to accept the challenge.

"Just like we saw before: if the curse is called out, and the challenge issued, the vampire has to show up and 1) defend its mate, and 2) negotiate with the wizard.

"It's quite cruel, but unfortunately legal, since it's the people with more power and influence in the ministry who use it to make deals with vampires."

"What about Snape's change of appearence?" Harry still wondered about that.

"That, I have no idea. Hopefully Dumbledore will be able to explain it later."

1) 'Tom Collins' Anyone realize where it's from? ... Rent! Yup, I did. Lol, we're doing 'Seasons of Love' in my Music Theater class, which goes w/ the play/movie Rent, which I just saw this Tuesday. Loved it! Tom is awesome, but I Just adore Angel! :D Anyway, Idk why I chose Tom's name, I just Needed to put it in there. Anyone who realized that gets a virtual cookie. =)

2) "Veniecum Sanguinous" I got from 'venient cum sanguine' (Sorry if it's inaccurate, I used Google Translate, but tried to be as exact as I could) which is supposed to be Latin for 'Come with blood'.

3) "Morsa Moris - Vam" is (again like the above, sorry if its inaccurate) supposed to come from 'mors amoris' which is supposed to mean 'death of love', and 'vampir' which is (the Romania version) of 'Vampire'. So it's supposed to be like 'death of the vampire love'.

4) I wasn't sure what to put there to describe the change in ethnicity - I'm not sure what he was to begin with aside from Caucasian/white, so I just put that. If anyone knows any specifics on what his original or perceived ethnicity (Not nationality) is, please let me know - then perhaps I could put more detail into this.

*5) There are 3 things here:

1. I made him secretly be part Asian - Japanese if you wan to be specific - because I've always liked the fact that he had dark eyes and black hair which I perceive as being more Asian than anything. I toyed with the idea and found it fun to do. A little spin on the character. Why he hid it will be discussed later.

2. Another reason for the above, Klaus, the vampire in the story, is his lover... and his seme. I wanted Severus to fit more of the stereotypical uke role.

3. Why he is/looks younger: This will also be brought up later. If you Really wanna know, I'll post spoilers. For now, let's just say it has to do with Klaus's influence. ;) I'll let you think on that a bit.

That's all for now. Anymore questions, don't be afraid to ask. People usually have to question my ideas to get where they came from. :)
