Author's Notes:
Harry and Snape angst! Couldn't help it, it's just too much fun when you torture the characters... I was having such a fun time writing (the end of) this chapter that I was having a hard time trying to keep my laughter in! I was writing during class.
Right, so in case there's some confusion as to why I keep switching between Harry and Darron... well, Harry is him in the future, and Darron is him (now) in the past. Harry/Darron himself is trying to separate himself into two, and I'm just trying to show how hard he's struggling with the task through words... doesn't work too well, since sometimes I use Darron when he's being Harry but that's because the people around him believes him to be Darron... does that make sense?
Please read & review!

NOW EDITED!

Disclaimer:
As usual, I own the name Darron... (no, I don't think I'll be giving him a last name) and the plot... Everything else (as in, the original stuff) is owned by J.K.Rowling and related staff and companies, and the movie people, too, I suppose.

Revenge!

The first week of school did not go well for Darron. If anything, he had never had as day as horrible as his first day of classes. Due to his nightmare and grief, he fell back asleep around 4:30 in the morning. Severus, not knowing anything about the new Slytherin's habits, left for breakfast alone. There, in the Great Hall, rumours were flying fast. The news of how Darron had shook hands with James Potter and Sirius Back had spread, plus the fact that these two proclaimed Slytherin-haters even dubbed the newcomer an Honourary Gryffindor. Even the fact that they had spent time together and had kept in touch the week or so before school started became common knowledge.

Severus had snorted to himself when he heard the news. He didn't know what to think of his roommate, from his nightmare last night to him being an Honourary Gryffindor. He made it a challenge to find out all the secrets behind the face called Darron. Now that he was part of the Gryffindor crowd, Severus had no qualms about getting him expelled as well. He received his timetable, glanced at it, and suppressed a groan. First class of the year - and incidentally of every Monday - was Defense Against the Dark Arts with the Gryffindors. Profess Sinadell was a strict but well-knowledgable professor, but highly disliked the students, Slytherins included, even though she was their Head of House. Sighing in defeat, he finished his breakfast and left for class, not realizing that Darron never showed up.

He stepped into the Defense classroom and sat down in his usual seat. Hearing loud, boisterous voices, Severus grimaced. The Gryffindors had arrived. Black shot him a glare before the four flopped down in their seats. Frowning, he wondered why Darron wasn't with them.Scannng the class, he noticed that Darron was nowhere to be found in the room. He was pulled out of his contemplation when Professor Sinadell strode in, exactly on time as always, and slammed the door behind her. The room fell silent - Sinadell was not known to be lenient. Once class started, no one was allowed to speak out of turn. Severus allowed himself to feel a small touch of pity for Darron before returning his attention to class.

(A/N: Sinadell likes to do the register automatically by magic, in case anyone wondered about that, lol.)

Elsewhere in the castle, Darron slowly came to, waking up from a happy dream where he had been practising Quidditch with the rest of the Gryffindor team - Ron as Keeper and Ginny a Chaser. For a while, he laid on his bed, disorientated. The room was pitch black. It was a few minutes before he remembered being sorted into Slytherin and his nightmare just a few hours ago. Grimacing, he groped around blindly, instinctively looking for his glasses before remembering he no longer wore any. He paused, then resumed groping, this time in search of his wand. After tripping over his own shoes, common sense finally returned to his sleep-emptied head.

"Oh, for... Lumos!"

All the room lights came on, as did the tip of his wand. Darron squeezed his eyes shut at the sudden onslaught of light. The regular Slytherins all knew how to control just how much light was needed, or just for their wands to light up. It was another minute or two before he could see properly without squinting. He looked up at the clock and his jaw dropped - it was already a third of the way through first period! Scrambling around madly, he quickly stripped and pulled on his school robes. Dashing out into the hallway, he paused. He hadn't received his timetable yet, so he had no idea what his first class of the day was. Deciding to talk to Professor McGonagall, he took off, feeling a sense of deja vu once again. After all, hadn't he been late for the first class as Harry in sixth year?

He burst through the doors of the Transfiguration classroom, scaring the second year Hufflepuffs. Darron grinned sheepishly before walking up to Professor McGonagall, who looked slightly angry at his interruption. Uncomfortably, he was reminded of Umbridge's inspection in McGonagall's class.

"I hope you have a good reason for interrupting my class, young man," the professor said sternly while taking in his appearance, from his tassled hair to the messiness of his robes, coming to the correct conclusion that he had just woke up and had no idea where to go. "Come here, I believe your professor will give you te proper punishment, so I will not add on to that." She pulled out a blank piece of parchment and conjured Darron's timetable on to its surface before handing it to him. "I hope you have a good day," she dismissed, giving him a pointed look.

Darron grinned, "Thanks, professor, sorry, I'll be on my way!"

He waved and left the classroom. Once outside, he glanced at his timetable and groaned; Defense Against the Dark Arts with Professor Sinadell. He took off down the hallway once again, praying madly that he wouldn't be torn to shreds by the professor who seemed to hold a grudge against him since he first woke up. It was like Potions all over again, except it was Defense and with a different teacher, though the feeling wasn't as strong as hate. Taking a deep breath, he knocked on the door, waiting for permission before entering.

The class was completely silent. The Marauders gave him sympathetic looks while the professor glared at him with something akin to utter loathing. After the last five years as Harry on the receiving end of Professor Snape's glares, Darron stared back levelly as he apologized. The class was amazed, no one dared to stare back at Sinadell when she was in a bad mood. The silence dragged on for a few more seconds before the professor spoke up.

"For your tardiness, Mr. Darron," Darron flinched at the name, "I shall have to punish you. Be ready!"

Almost half of first period had passed, he was very late indeed. Darron lowered his bag on to the floor and pulled out his wand. Briefly, he worried about the attack, but soon shook it off. He had faced Voldemort multiple times, survived Avada Kedavra as a 15-month-old baby, successfully thrown off the Imperius curse, suffered through Crucio, and had been casting the Patronus Charm since his third year. Combined with his work as the DA teacher, Darron - after shaking himself out of his "Harry" memories - decided he had nothing to worry about. And he didn't need to.

"Legilimens!"

Darron's eyes merely widened in surprise. Now he was definitely glad that he had mastered Occlumency before he left. This attacked, othing like the ones Snape had cast on him, simply bounced off his mental defences. He couldn't help it - he smirked. Everyone gaped at him, professor included. It was a while before Sinadell finally found her wits and ended the staring contest.

"Impressive," she muttered begrudgingly, "have a seat, Mr. Darron, and take out your books. Twenty points from Slytherin for your tardiness and you better not be late ever again."

"No ma'am!" Darron chirped cheerfully as he slid in beside Severus, the only free seat left in the class.

Professor Sinadell glared at his tone of voice before resuming class. Sirius and James risked getting caught to flash him a thumbs up. Severus ignored him, as did the rest of the class for fear of the professor's wrath. The remainder of class did not improve either, despite the fact that they only went over the NEWT objectives. For each spell mentioned, Sinadell forced Darron to cast it, even though they were supposed to be learning them over the next 2 years. Surprisingly, he already knew a fair portion of the spells - nearing half - but even so, Sinadell made a snide remark every time they came to one he didn't know. Finally, fed up, his stomach growling painfully, he pointed his wand at the professor and summoned his stag Patronus. Bad idea.

Sinadell was shocked. Patronus was such an advanced charm that even first-and second-year Aurors-in-training had difficulties performing. All four Marauders paled at the sight of the stag. Darron realized his mistake too late. Without stopping to grab his bag, he fled the room. After a quick visit to the kitches for some much needed food, he holed himself up in the Room of Requirements, willing it to take on the appearance it did for the DA meetings. In there, he sat without seeing anything. His mind supplied the images, from the first time the DA had met here and came up with the group name and elected him leader, to their first lesson on Expelliarmus, to Christmas and Dobby's decorations, to Patroni, and finally to the lesson when Dobby warned them to leave and hide, leading to Dumbledore disappearing. He, as Harry, hadn't found the time to resume the lessons in sixth year, and this fact depressed him greatly. It was lonely, so lonely, being here and pretending to be someoneelse when all he wanted was to hug his parents, Remus, and Sirius and never let go. It hurt too much, to be all alone after all he had been through at Hogwarts and the friends who stood by him.

When he finally came out of his trance, it was already halfway through lunch. Glaring blearily at his watch, he painstakingly got up and trudged to the class after lunch, Charms. He flopped down in his - Harry's - usual seat and buried his head in his arms. His world was coming apart and he didn't know how to fix it Groaning, he lost himself in his memories again, thinking of first year when Hermioney berated Ron for his pronounciation for Wingardium Leviosa or Seamus setting the feather on fire, or in second year when Ron had snapped his wand couldn't cast a single spell correctly...

Severus had finished his lunch early and came into the classroom. Upon seeing Darron in his seat, he paused, startled. Quickly, he snapped out of his stunned state of mind and sat down in the seat beside the boy curled up on the desk. Deciding that it was a good time to confront the amnesia fraud, he cast a quick charm to warn him of anyone coming and turned to prod his roommate.

"Go away, Ron," Darron was in Harry-mode, stuck in his memories.

Severus grinned, he had heard the name last night, and ignored the order - after all, he wasn't Ron - and continued to prod, feeling a sense of twisted glee.

"Ron! Bugger off! I'm trying to think!"

Severus had no idea what Ron's voice was like but tried anyway, "about what?"

Darron was too lost in his own mind to notice the difference, "just stuff."

"What stuff?"

"Ron..." Darron groaned.

"Come on, you can tell me," Severus took a risk, "I'm your best friend."

"Where's Hermione?" Severus had heard that name last night, too.

"In the library?" he chanced.

Darron snorted before sighing.

"Well?" Severus tried again.

"Nothing!"

"There's got to be something."

"Ron!" Darron - Harry, he didn't even know anymore - exploded, "Leave me alone!"

"No," Severus smirked, so close.

"Ron!" Darron finally lifted his head up, "you won't und..."

Severus' smirk grew bigger at Darron's pale and horrified face, knowing that his fellow Slytherin knew his secret had been found. Darron, for his part, groaned. He hadn't even lasted 24 hours with the students and he had already been caught. How hopeless, he could trick even Dumbledore, but not Snape, never mind that it was the 16-year-old version of the man he knew.

"I knew it!" Severus had the same triumphant gleam in his eye the same night he had caught Sirius in Harry's third year. "You are faking your amnesia!"

Darron groaned once more and buried his head again. He made an accurate guess that Severus had heard him talking in his sleep and came to the conclusion.

"How Slytherin of you," Severus' tone was the same as when he blamed Harry for being Gryffindor in the future, "fooling even Dumbledore."

Darron flinched - the tone brought back unhappy memories. He was having a hard enough time separating his memories from his present reality, and as usual, Snape wasn't helping things.

"I can go and tell Professor Dumbledore right now and get you expelled. Even better, I can talk to Professor Sinadell."

It was too much in one day. All his previous dislike and loathing for the hated Potions Master swelled up in Harry. For all the times he wanted to hex the man, he could now. The current Severus Snape stood at his height and lacked the experience aura of striking fear and terror into those around him that he carried twenty years in the future. A vindictive grin came to Darron's face as he wished that Ron was there with him, as well as poor Neville. Whipping his wand out, he let lose his emotions and fired every single jinx, hex, and curse he knew at the unsuspecting Severus.

Feeling supremely elated and satisfied when he finally finished - five years of grudge had been repaid, he grabbed his bag and ran for it, but not before Professor Flitwick rounded the corner and saw his disappearing form. Worried, the professor hurried into the classroom only to find the unrecognizable Severus. Shocked - Darron had never shown such violent tendencies during the weeks before school - the tiny Charms professor stood rooted at the doorway for a good five minutes before the noise of students coming towards the class returned him to reality. Severus was soon flooed to the hospital wing followed by his bag.

News travelled like comets streaking through Hogwarts. Even James and Sirius combined hadn't done such damage to the unpopular Slytherin. Everyone was disturbed but agreed that Darron had been rightly placed in Slytherin. Darron was caught that night as he tried to sneak into the kitchens after missing dinner. He wasn't expelled, although it might've been an easier punishment. Instead, his wand was temporarily confiscated and he was suspended from doing any magic for a week. A month of detentions with Sinadell and Filch alternatively plus a professor escort between classes and a 24-hour curfew summed up his "vicious attack". Apart from classes and meals, Darron wasn't allowed to leave the Slytherins' dormatories at all.

Severus took a good six days to heal. He was tempted to blow Darron's cover, especially when Dumbledore had questioned him alone, but feared a second attack. When he finally saw his roommate after leaving the hospital - he was surprised to find that Darron tried to visit him but was banned by Madam Pomfrey - Darron hadn't said anything. Neither spoke to each other for a very long time after that, until the early hours of the morning after a fateful full moon night.

End Notes:
Hope you liked the chapter! You can probably make a good guess as to what the next chapter will be about. Now, how to go about writing it... Anyway, is this a good pace or are you all impatient for Harry and Severus to get together? Oh yeah, another thing, usually, when I use "Snape", I mean the professor and "Severus" refers to the current 16-year-old boy. Not sure how I'll get them together, since I've never really tried writing romance stuff before. Hmm...
Ah, yes... please read & review! It makes me very happy!
