AN: Happy 2015 to all of you! Wow, it been awhile since the last update, sorry about that!

*AvaLongbottom- I'm glad that you are enjoying this story! I fully intend to continue and finish this story (no matter how long it takes) so I hope that I don't disappoint you! :D

*Vio587- Thank you very much! I'm happy to add a different take on this type of fic :)

*NottDeadYet- I'm proud to help fuel your obsession ;) it is quite an honour for this fic to be one of the best in your opinion!

*Lightning Nova- Aww! You really are too kind! Rest assured there will be no romance between Harry/James and Snape only a growing friendship *tries to stop blushing*

*ibliniy- No, I don't think Harry will tell Lily. Imagine if the guy that's been trying to date you for years suddenly says that he if your son inhabiting his father's body (oh yeah and the two of you got married!). At the best Lily would think it was some sick joke, at the best Harry might get himself committed to St. Mungo's. I do like your theory that this is what caused James to be a better person though!

*Ceti H. Black- Not as soon as I would have liked (sorry) but here you go!

Hope you enjoy this long-overdue chapter!

Severus looked at Harry uncertainly. His gaze still held the traces of panic, and Harry was saddened to see the slightest glistening of tears his eyes. Severus swallowed –Harry could almost hear the gulp in the silence that had taken over the classroom– and nodded. The motion was shaky –as if he expected Harry to suddenly change his mind and run out of the room to report him to the first Professor he could find.

"Severus," Harry said, trying to set his mind at ease. "I'm not going to tell anyone. You didn't mean anything by it, I know you didn't!"

Severus nodded again, but remained silent.

Harry sighed.

"I know that it's not in your nature to trust easily, Severus." Harry said. "So I won't ask you to trust me after only ten minutes of being friends. I'll take an Unbreakable Vow if that's what it takes for you to believe me."

Severus' distrust quickly gave way to his shock. He gaped openly at Harry for a few moments before he found his voice.

"You're serious?" Severus asked.

"I am." Harry nodded.

"You would do that?" Severus asked, his eyes wide.

"I would." Harry's tone held no hesitance. "If that's what it takes."

Harry held out his hand for Severus'. His was wand slightly raised, pointed at his outstretched hand. Harry looked Severus dead in the eye, the serious expression on his face made him look like the man James Potter would one day become.

"We can do it now if you want." Harry said.

Severus took in the image before him. His former long-time enemy, willingly offering to make a vow to him that could kill him if he broke it. The seriousness on his face… all so that he (Severus) would trust him.

Severus shook his head.

"No." He said. "I believe you, James."

Harry's serious expression gave way to a huge grin.

"Thank you, Severus." He said.

"But you leave me in your debt, James." Severus said, a small frown crossing his face.

"Seve-"

"No!" Severus cut Harry's refusal. "I do not like to be in debt, James, not even to friends. Tell me how I can make this up to you."

Harry frowned. Severus thinking that he was in his debt was laughable, but only Harry could appreciate the irony. However, Severus would not be dissuaded. An idea occurred to Harry.

"Alright, Severus." Harry said. "I'll tell you what. You let me help you learn the Patronus Charm. The second you perform a fully corporeal Patronus, your debt with me will be squared."

Severus quirked an eyebrow.

"You really don't give up, do you?" Severus asked.

Harry held out his hand.

"Do we have a deal?" Harry grinned.

Severus smirked. He reach out and shook Harry's hand once.

"Very well, James." Severus said, his tone suggesting bemusement.

Harry just chuckled in reply.

"How long do reckon until Harris comes back?" Severus asked.

Harry checked his watch.

"I'd say about ten minutes." Harry said.

Severus nodded in reply. He went back to lean against the wall, Harry followed suit.

A silence stretched between the two boys. Neither one of them knew what to say the other.

"… I've never heard of that spell you used." Harry said after a while.

Severus stiffened next to him, but Harry persisted –making sure to keep his tone non-threatening.

"Where did you learn it?" Harry asked curiously.

"I-I made it up." Severus said softly.

"Wow!" Harry exclaimed. "By yourself?"

He, of course, already knew that Severus had made up the spell himself, but that didn't mean he wasn't impressed by Severus' accomplishment. Especially considering his age!

Pink tinged Severus' normally pale cheeks.

"Uh… yeah." He said. "By myself."

"That's bloody brilliant, Severus!" Harry exclaimed.

Severus allowed a small smile to form, before he frowned again.

"It didn't work the way it was suppo-"

"I'm sure you just need to tweak it a little!" Harry cut him off. "Although I'd rather not be part of the testing the next time, if it's all the same."

Severus' eyes widened, then he saw Harry's joking grin.

"Git." Severus muttered good-naturedly.

Harry's grin stretched wider.

At that moment, the door to the classroom opened and Professor Harris walked in.

"Mr. Potter, Mr. Snape." Harris nodded to both of them.

"Professor." Both boys greeted him politely.

"Any progress Mr. Snape?" Harris asked.

Severus scowled at the stone floor.

"… No Sir." Severus answered.

Harris raised an eyebrow.

"Look my in the eye, young man." Harris ordered firmly.

Severus raised his head obediently, but when he looked in Harris' eyes, he found some soft, warm, and understanding emotion directed at him.

"Mr. Snape," Harris said. "This spell is not a part of your curriculum, you will not be tested on your ability to produce a Patronus Charm. I, myself, know several fully-grown witches and wizards –powerful witches and wizards, mind you– that cannot produce this particular charm. I merely showed it to you and your classmates for fun. It says nothing about your magical abilities that you cannot produce this charm after only one day of trying."

Severus stared back at him, speechless in the wake of his Professor's speech.

"To tell you the truth," Harris continued, "The only one of you classmates who's Patronus might have actually repelled a Dementor was Mr. Potter's, and even he might be unable to cast it in the presence of a real Dementor!"

Harry nodded gravely, fighting back a smile. He reminded himself that he was supposed to be James Potter. James Potter certainly hadn't learned the Patronus Charm and used it to repel a hundred Dementors at the age of thirteen!

Severus raised both his eyebrows in astonishment.

"Really, Sir?" Severus asked.

Harris smiled.

"Yes, Mr. Snape," he said, "really."

Severus considered this information, then cracked a smile of his own.

"Thank you, Sir." Severus said.

"You're welcome." Harris nodded once. "Now you boys had better be off, or you'll be late."

Both boys' eyes flicked to the clock and saw they had just over five minutes to get to their next classes. They grabbed their bags and hurried out of the classroom with rushes goodbyes to their Professor.

"What class do you have now?" Harry asked as they jogged through the hall.

"Potions." Severus answered. "You?"

"Transfiguration." Harry answered, trying not to chuckle and say 'of course it would be Potions'. "Want to meet outside during Lunch?"

Severus considered the offer, then nodded.

"Alright." He said.

"See you then." Harry said.

If any of the other students on their way to class noticed a Gryffindor and a Slytherin waving to each other as they parted ways, they didn't comment.

AN: TA-DA! What did you think?

I can't promise the next chapter will be up next week. I'm starting my first year at University this year, so updates might not be on a set schedule. I'm really sorry about that, but it really can't helped. I can only promise that I will update when I can. I hope that you will be patient with me, and I really hope that it's worth the wait when I do update.
